Abstract: TDB-15-2: Fan-delta experiment performed in Tulane University Delta Basin. Experiment evolved under constant sea-level rise rate of 0.25 mm/hr, and variable forcings of water and sediment. After run hour 300, water discharge alternated between 0.14 L/s and 0.45 L/s, and sediment discharge alternated between 0.00014 L/s and 0.00045 L/s. Prior to run hour 300, water discharge was 0.17 L/s, and sediment discharge was 0.00017 L/s. Experiment used a strongly cohesive sediment that had a wide grain size distribution with a median diameter of 65 microns. Total experiment run time was 733 hr, variable discharge began after hour 300. Experiment was paused every 1.1 hours for data collection. After variable flow was initiated, the following data were collected during each 1.1 hr cycle: -Overhead photo during low flow conditions -Overhead photo during high flow conditions -Overhead photo during experiment pause while delta top was dry. -Topographic scan during high flow conditions. -Topographic scan during pause/dry conditions. Data Files: Folder "TDB_15_2 Original Data" contains overhead raw overhead photographs (.jpg) and scans (point cloud .xyz). Each row of the point cloud contains the following data: [row col X Y Z R G B]; Folder "TDB_15_2_Results and Processed Data" contains overhead photograph and scan data gridded to a 5mm x 5 mm grid. Gridded data begins at hour 535, after the final scanner physical location was established. RGB color data included in the "Scans_Gridded" folder was collected with the scanner, at the same time as topographic (Z) data. All length data (X, Y, Z) are in meters. All colors (R, G, B) are in intensities from 1 to 255. Colors in gridded data sets may be non-integers because of the interpolation process. A value of NaN indicates no data in that grid cell.

Title: Steady and transient sand bedform evolution at Clear Run, North Carolina, September 2009
Persistent ID: http://doi.org/10.5967/M0GM85FG
Creator(s) Raleigh L. Martin
Abstract: The evolution of sand bedforms through time was observed through time-lapse overhead camera imagery at Clear Run, a small, sand-bedded stream in Wilmington, North Carolina, USA. These observations were made as part of a larger study of "hyporheic" (i.e., surface-subsurface) solute and fine particle exchange through the injection and tracking of tracer solutes and particles in the stream channel. In particular, two scenarios were considered for observing hyporheic exchange and associated bedform evolution: (1) steady background "base" flow conditions, and (2) time-varying "flood wave" conditions associated with the opening of an artificial dam upstream of the observation section on the stream. The overall study is described in Harvey et al. (2012, Journal of Geophysical Research 117, G00N11, doi:10.1029/2012JG002043). This dataset contains processed images for the steady and transient bedform evolution observed at Clear Run on September 18, 2009. The images provided here were captured with a Nikon D5000 camera looking downward from approximately 2.5m above the stream bed. Time-lapse images were captured every 30 seconds. The images were rotated to align with the stream channel geometry and cropped to remove the stream banks and other non-bedform components of the image. Steady-flow images were further processed to normalize for variation in lighting. Specific details for each set of images are provided here: (1) Steady base flow observations (individual .jpg images contained in folder "ClearRunSteady_CroppedRotatedNorm") Images numbered 12 to 588 (577 total images, numbers increasing through time) were captured at 30-second intervals during steady base flow conditions on 18 September 2009, starting at 11:00:32 AM local time (Eastern Daylight Time). In all images, flow is from left to right. The vertical (spanwise) extent of the images is 2664 pixels (175.0 cm), and the horizontal (streamwise) extent is 1520 pixels (99.9 cm), based on a conversion factor of 0.0657 cm/pixel. (2) Transient flood wave observations (individual .jpg images contained in folder "ClearRunFlood_CroppedRotated") Images numbered 1 to 300 (300 total images, numbers increasing through time) were captured at 30-second intervals during the artificially-induced dam-release flood wave on 18 September 2009, starting at 4:08:32 PM local time (Eastern Daylight Time). In all images, flow is from left to right. The vertical (spanwise) extent of the images is 2904 pixels (201.8 cm), and the horizontal (streamwise) extent is 1612 pixels (112.0 cm), based on a conversion factor of 0.0695 cm/pixel. An additional metadata file ("ClearRun_metadata.xlsx") provides timing information for each of the photos in the steady and transient flow collections.
Title: Transient Flows Unimodal sediment
Persistent ID: http://doi.org/10.5967/M0S180MK
Creator(s) Colin B. Phillips
Abstract: Sediment transport experiments with variable water discharge conducted at St. Anthony Falls Laboratory, University of Minnesota. These experiments explore the effects of flood hydrograph shape on bed-load transport dynamics. The dataset is composed of over 200 individual experimental runs with varying discharge and sediment feed rates for a unimodal sediment mixture with a median size of 7 mm. Raw data included in this data set for each experimental flood includes time series of varying water level and force on the load cell due to the accumulating sediment flux. These data are processed into time series of water depth, dimensional and dimensionless stress, sediment mass, and sediment flux for each run. Accompanying these data are topographic scans of the sediment bed of 1 mm vertical and spatial resolution.

Title: Flood Intermittency and Delta Islands
Persistent ID: http://doi.org/10.5967/M0BZ645X
Abstract: This experiment is part of a larger ensemble exploring flood intermittency and delta island growth. They were conducted in the Surface Transport and Earth-surface Processes (STEP) Basin, located at the Morphodynamics Laboratory at the University of Texas at Austin. The experimental domain is 1.85 m x 2 m with a water depth of 50 mm over a 50-mm thick sediment bed. The bed is composed of the same grain size as the input sediment: fine quartz sand, with a D50 of 171 µm and a density of 2650 kg/m3. A computer controlled pump and auger feed the sediment and water (0.355 l/s at a concentration of 1:100) mixture into a bucket with an Arduino-controlled knife valve that connects to the domain inlet by a 2 inch PVC pipe. The water level in the STEP basin is maintained by a computer controlled weir, constraining water level within 1 mm of the 50 mm above the initial sediment bed height. The tank does not recirculate, and all the sediment from the flows remains in the domain during the experiments. The experiments were recorded with overhead time-lapse imagery, a photo taken every 15 seconds. The overhead images were preprocessed, correcting for lens distortions at the edge of the frames.
Title: Canopy Data and Applications Rescue Effort
Persistent ID: http://doi.org/10.5967/M04J0C60
Abstract: These materials document a 'data rescue' effort undertaken as a collaboration between the leaders of the original research projects, students and staff at TESC, and the SEAD DataNet project. This effort involved gathering and organizing the existing materials, and a significant effort to annotate materials to enhance reusability. The effort's scope included preserving the projects' web documentation, image archive, software products (executable and source) including a database generation tool and visualization software, paper publications, and the field study data recorded using databases generated using the projects' database generator tool. In addition to preserving the original database files, the rescue effort converted all databases into a standard format (Software Independent Archiving of Relational Databases, http://www.eark-project.com/resources/specificationdocs/32-specification-for-siard-format-v20) and experimented with capturing a full virtual machine to provide a general mechanism to support live queries of the databases in the future. The included poster from the 2015 AGU conference describes the early parts of the effort. Our team wishes in particular to acknowledge the contributions of Michelle Wallace and Sharon McIntee, who had the primary responsibility for assembling materials, organizing them in SEAD, adding formal and informal (tag) annotations, and generating the SIARD and Virtual Machine forms of the databases.

Creator(s) Van Pelt, R., and N. M. Nadkarni
Abstract: The goal of the Evergreen-DNR Leave Tree Project is to help forest managers use results from forest canopy research to help determine which trees to leave when harvesting a stand of trees. This project hopes to articulate how statements of policy that determine which trees to leave, e.g., "leave those trees that increase wildlife habitat", might be made more specific, and to refine definitions terms used when specifying leave tree requirements, such as: complex structure, broken tops, large branches, crown gap, continuous crown. The Leave Tree Project is currently gathering and analyzing data on how experts categorize crown shape and what they mean by certain commonly used terms such as "wildlife tree". We hope to develop an understanding of how crown structure relates to ecological values such as wildlife habitat. We are distributing a questionnaire and tree structure catalog to a panel to experts. The answers from the questionnaire will help us to determine commonalities that might be used to query our database for trees that satisfy certain structural features that, in turn, equate to particular ecological values.

Title: Videos of lofting and ground-hugging turbidity currents
Persistent ID: http://doi.org/10.5967/M0Z0368W
Abstract: Videos from experiments performed in 2015 at the University of Texas at Austin. These lofting videos are of experimental turbidity currents with light interstitial fluid, achieved by heating interstitial fluid to 31 deg. C and keeping ambient tank water at 23 deg. C. Sediment concentration is varied between 1.5%, 2%, and 3% in these flows. Ground-hugging flows have the same density (i.e. temperature) interstitial and ambient water and have 1.6% sediment concentration. See the table included with this dataset and Steel et al., 2017 for all experimental conditions and results. These videos are meant to supplement results published in Steel, E., Buttles, J., Simms, A.R., Mohrig, D., and Meiburg, E., 2017, The role of buoyancy reversal in turbidite deposition and submarine fan geometry: Geology, 45(1), 35-38. doi: 10.1130/G38446.1

Abstract: This dataset includes data from flume experiments run in 2014 at Arizona State University investigating bedload transport and turbulent structures downstream of a 3.81 cm backward-facing step. Two high-speed cameras captured bedload motion and motion of neutrally buoyant particles in the flow at 9 different distance downstream of the backward-facing step. Bedload transport data were collected using manual particle tracking techniques on the bedload images. Neutrally buoyant particle images were run through Particle Image Velocimetry algorithms to generate a two-dimensional field of fluid velocity vectors. Acoustic Doppler Velocimetry data were also recorded to refine fluid velocity measurements.

Title: Sand on Salt - dune subsidence into a mobile substrate (PDMS)
Persistent ID: http://doi.org/10.5967/M09K487M
Abstract: This collection contains time-lapse photographs from experiments conducted by A. Piliouras and W. Kim, the results of which are published in Piliouras et al., (2014) in Lithosphere: http://dx.doi.org/10.1130/L323.1. More detailed methodologies can be found in the manuscript. Seismic data from the Gulf of Mexico showed evidence of large lenticular sand bodies (linear dunes) partially subsided into the underlying Louann salt. The dunes were preserved after a marine transgression, and they had variable preserved topographies. We performed experiments to determine what controlled dune subsidence rates and the amount of subsidence, such that we might produce variable subsided dune topographies. The dune here is intended to be a cross section through a linear dune, so it is essentially a triangular pile of sand (silica) deposited relatively instantaneously on top of PDMS (polydimethylsiloxane), which we use as a proxy for salt (see references within Piliouras et al., (2014)). Run 1 has a sand to salt thickness ratio of 1 (sand thickness = salt thickness = 14.5 cm), while Run 2 has a ratio of 0.5 (sand thickness = 7.5 cm, salt thickness = 14.5 cm). Here we supply the original time lapse images and corresponding movies, as well as images corrected for camera lens distortion. Run 1 time lapse photos were every 5 minutes, and Run 2 time lapse photos were every 3 minutes. The lens corrected photos have 1 pixel = 1 mm. Flume dimensions can be found in the manuscript listed above to resize and/or process the raw photos.

Fluvial bevelling of topography controlled by lateral channel mobility and uplift rate. Nature Geoscience., 9(9), 706-710, doi:10.1038/ngeo2773. For each experiment photographs were taken at regular intervals with a 10.5-mm, f/2.8 fisheye lens mounted on a DSLR camera. Fisheye distortion was removed using the inbuilt lens correction in Photoshop CS6 and were tilted such that the average slope of the alluvial fan is horizontal. Photos taken while the water was not running or when the dye feed was interrupted were not used. Moreover, for Run 4 only photographs from the first 25 h of runtime were processed and uploaded to the repository. All raw unprocessed images can be obtained upon request. Topographic data of the basin were acquired using a custom built laser scanner that was programmed to cover the entire basin except for its upper ~5% (~25 cm), in six swaths. The scans are provided as .dat file and have 4672 by 3001 mm2 sized pixels. To open the datafile in MATLAB : id=fopen(‘filename’,'r') A=fread(id,[4672 3001],'float'); fclose(id); The Metadata for the experiments is summarized in an excel spreadsheet. For each run there are entries about the input parameters as well as the timing of uplift events and the timing of topographic scans. In addition, timelapse videos of each run are included. For each run, the frame rate is 24 frames per second. With 1 minute between each picture, there are 24 min of real time in one second of the video.

Abstract: This collection includes data developed and used for the analysis of the Birds Point-New Madrid (BPNM) Floodway activation in 2011. The data collection includes 10 items, all of which present the processed and derived data. The processed differential LiDAR is the 2005 (pre-flood) LiDAR subtracted from the 2011 (post-flood) LiDAR and corrected for flight line errors. The original LiDAR data were obtained from US Army Corps of Engineers. There are 5 simulated maximum velocity data items from HydroSed2D at two locations (O’Bryan Ridge and Ten Mile Pond) and 2 simulation cases (vegetation and no vegetation). The maximum velocity data for the entire Floodway is for the vegetated case. The NASA AVIRIS dataset is classified into classes representing woody vegetation and bare soil. The soil dataset (K/T) is an erodibility index derived from USDA SSURGO data. Additional data for this study was provided by the USGS, and is available along with the report at the following site: http://pubs.usgs.gov/pp/1798e/. This data includes ADCP (Acoustic Doppler Current Profiler) flow measurements from the inflows an outflows of the Floodway, and HOBO depth sensor measurements from various points within the Floodway. This data were used to validate the HydroSed2D simulations.
Title: Landscape evolution experiments - hillslope process control on drainage density
Persistent ID: http://doi.org/10.5967/M09P2ZM3
Abstract: These data are the raw and processed digital elevation models for the sandbox experiments detailed in "Experimental evidence for hillslope control of landscape scale" by K.E. Sweeney, J.J. Roering, and C. Ellis, which was published in Science in July of 2015. Landscape evolution theory suggests that climate sets the scale of landscape dissection by modulating the competition between diffusive processes that sculpt convex hillslopes and advective processes that carve concave valleys. However, the link between the relative dominance of hillslope and valley transport processes and landscape scale is difficult to demonstrate in natural landscapes due to the episodic nature of erosion. Here we report results from laboratory experiments combining diffusive and advective processes in an eroding landscape. We demonstrate that rainsplash-driven disturbances in our experiments are a robust proxy for hillslope transport, such that increasing hillslope transport efficiency decreases drainage density. Our experimental results demonstrate how the coupling of climate-driven hillslope- and valley-forming processes, such as bioturbation and runoff, dictates the scale of eroding landscapes.
Title: Streamlab 2006
Persistent ID: http://doi.org/10.5967/M02B8W0V
Abstract: StreamLab06 was a multiphase research endeavor involving academic researchers, federal agencies and stream restoration practitioners. This ongoing project is being conducted in the Main Channel at the St. Anthony Falls Laboratory in Minneapolis, MN. The StreamLab program brings together a spectrum of research expertise (stream ecology and biology, engineering, hydrology, hydraulics and geomorphology) to conduct focused studies on a laboratory controlled, field scale, indoor stream environment. The first phase of the StreamLab06 project was completed in late March, 2006, and was focused on testing several existing and one new technology for sampling bedload transport. Technologies were tested in separate sets of sand and gravel trials. For the former, the channel was pre-loaded with sediment consisting of nearly uniformly sized (approximately 0.8mm) sand. Transported sand was captured in the channel's weigh pans, weighed, and recirculated. The water discharge varied (from trial to trial) between 2.0 and 3.6 cubic feet per second. Three standard "manual" samplers were tested: a 3" Helley-Smith, a 3" BL84 and an Elwha Sampler. For each, samples were taken at a fixed lateral position in the flow, just upstream from the weigh pans. Samples were taken over times varying from 15 seconds to one minute to see what sample-time would be necessary to capture natural variability in the sediment transport. In addition to these samplers, two (1200 and 600 kHz) Acoustic Doppler Current Profilers (ADCP) were installed and tested. These units just touch the water surface, and have the potential to deliver non-destructive information on sediment transport. For this experiment, researchers concentrated on the zones just upstream and downstream of the unit. In the downstream zone, which was just upstream of the weigh pans, a velocimeter (16mHz Micro ADV) provided a velocity profile of the flow, which will be used to calculate bed stresses. Finally, a 100 frame-per-second digital video camera capable of resolving individual grains captured the flow as it passed through the downstream zone. For the second set of trials, the sand was cleared from the channel, replaced with gravel, and several runs with varying discharges (up to a maximum of 5.5 cubic meters per second) were conducted.

Abstract: This is the SRTM dataset. The Shuttle Radar Topography Mission (SRTM) obtained elevation data on a near-global scale to generate the most complete high-resolution digital topographic database of Earth. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000. SRTM is an international project spearheaded by the National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration (NASA). --- Obtained on 5/30/2007 from: 30m US: ftp://e0srp01u.ecs.nasa.gov/srtm/version1/United_States_1arcsec/1arcsec/ 90m World: ftp://e0srp01u.ecs.nasa.gov/srtm/version2
Title: XES Basin

Abstract: The XES facility is a large experimental basin (13 m x 6.5 m), developed and built with funds from NSF and the University of Minnesota , that permits the formation of stratigraphy through the use of a flexible subsiding floor. The goal is to reproduce the real-world (i.e. spatially variable) kinematics of subsidence, as determined by geophysical modeling and backstripping of real basins. The floor is a honeycomb of 432 independent subsidence cells (Fig. 1) through which a gravel ""basement"" is slowly removed to provide accommodation space for deposition. At the beginning of an experiment, the basin is filled with dry, well sorted commercial gravel. The top of the gravel is covered with a thin rubber membrane. The experimental deposit is formed on top of this membrane. Subsidence is induced by withdrawing gravel from the bottoms of the hexagonal cells. Each hexagon forms the top of a cone that tapers into a standard elbow pipe (Fig. 2). The gravel in the cone rests at the angle of repose in this elbow. Subsidence is induced by firing a pulse of high-pressure water into the gravel in the elbow. A small volume of gravel is knocked out of the elbow and falls into an exhaust line, where it is transported out of the system and stored for later reuse. Each subsidence cell has its own sealed pressure tube that drives the pulses via a computer-controlled solenoid valve. We have refined and calibrated the pulsing so that each pulse produces about 0.12 mm of subsidence: the ""earthquake slip"" in the experiments. This is about equal to the resolution with which the basement elevation can be read (described below), and also to the typical grain size of sediment in the experiments. Hence the subsidence is effectively smooth and continuous in time. The subsidence is also spatially continuous. The cells are separated only at floor level, so the gravel can flow laterally to accommodate differential subsidence with no breaks at the cell boundaries. Firing a single cell, for instance, produces a smooth bowl-shaped subsidence pattern that extends over the six adjoining cells. Extensive testing has shown that the underlying honeycomb structure is not imprinted on the subsidence at the surface until the rubber membrane (the top of the basement) has been lowered to within about 0.2 m of the honeycomb. This leaves about 1.3 m of usable accommodation space in the basin. As long as the gravel basement is loaded, lateral slopes of up to 60 can be produced between adjoining cells Premixed sediment and water can be fed from anywhere along the perimeter of the basin, and the level of standing water is independently set by a computer-controlled head tank mounted outside of the basin. Thus, base level (in effect, eustatic sea level) can be raised or lowered independent of events within the basin. During an experiment, the surface flow pattern is recorded using video and still cameras. In addition a topographic scanning system, based on the design of Rice and Wilson (1988) and Wilson (1990), allows us to document separately the 3-D evolution of the surface topography during the run for later comparison with the surface-flow images, the preserved deposits, and theoretical predictions. Once the experiment is complete, the tank is pumped dry and the resultant deposits are cut in a series of precise parallel faces, beginning near one edge. Each face is then photographed. At greater intervals, a peel is taken of the cut face. This serial microtome process allows us to build a 3-D image of the deposits by stacking the sequence of photographed slices.
Title: Riparian Vegetation and Braided Stream Dynamics
Persistent ID: http://doi.org/10.5967/M05M63MB
Abstract: Goal: 1. To study and quantify the interactions between riparian vegetation, channel morphology, and flow dynamics. 2. To investigate how river systems self-organize as a result of these interactions. 3. To investigate spatial and dynamic scaling in braided rivers with and without vegetation. Reseachers: Michal Tal, Chris Paola, Elizabeth Tilman (Water Resources, Univ. of MN), Efi Foufoula-Georgiou (Civil Engineering, Univ. of MN) Result: Ongoing experiments at the St. Anthony Falls Laboratory are designed to isolate the effects of vegetation on braided stream dynamics. These experiments show how a fully braided stream with a noncohesive bed transitions to a single-thread (meandering) system when continuously forced with vegetation. Time-lapse photography and measurements of bed topography, flow depth, sediment output, and flow velocities enable us to study and quantify the morphodynamics of the system associated with this change.
Title: Delta Basin
Persistent ID: http://doi.org/10.5967/M0Q23X66
Abstract: The Delta Basin is a square flume measuring approximately 5 meters by 5 meters, and is 0.61 meters deep. The exact experimental configuration may vary depending on the scientific objectives - the specific scheme at right represents that for the DB03-1 and DB03-2 experiments. A mix of sediment and water are introduced at a single infeed point in one corner of the basin. This produces a radially symmetrical delta-like deposit. A syphon-based ocean controller at the opposite corner allows for precise base-level manipulation, and specifically for the creation of accommodation space via a slow base-level rise. Data Topography on the fluvial surface is measured using a laser-line system: laser lines (three are shown in the schematic) are projected onto the fluvial surface, and photographs taken at regular intervals by a camera on a fixed mount. Surface processes are recording using the same camera in time-lapse mode. Stratigraphy is recorded by slicing the resulting deposit and photographing the faces (with the same camera). "Peels" are also taken of the faces. By using the same camera in the same position, image data from all three data sets may be directly compared. --- DB03-1 Corrected surface images Images of the fluvial surface taken during the DB03-1 High Frequency Topography. See project description for details. The original images were taken every 15 seconds of run time and stored in Nikon's NEF format. These images have been corrected (for lens distortion and perspective) using Andromeda Software's Lendsoc Photoshop filter, and saved in JPG format. Images are stored in folders by calendar date. The file names are of the format "Ryyyy-mm-dd-hhmmss.jpg" where "R" stands for "run" (vs "T" in other experiment images for "topography") - note that the date/time is calendar not runtime - images with the runtime in the file name are elsewhere in the archive. DB03-1 Deposit Face Images Images of the DB03-1 Deposit stratigraphy. The deposit was sliced at the 1.5, 1.75, and 2.0 meter downstream transects, corresponding to the locations where surface topography measurements were taken. Another set of images is of a stream-wise face approximately at the center of the delta. Images are in Nikon's proprietary NEF format, and are uncorrected. DB03-1 Elevation Data These Excel workbooks contain fluvial surface elevation data from the DB03-1 experiment. See the readme. In the "cleaned_and_renamed" folder, the data have been cleaned up (redundant data removed, out-of-range data removed, worksheet names corrected, etc) but otherwise are unaltered. The "runtimetablefinal.xls" workbook has a table for converting the topo image file names (built from calendar time) into experiment run time. Data records pixels-above-bottom-of-image. Bottom-of-image is common to the topo images, surface images and deposit face images for correlation purposed. The data was created by analyzing the topo images (see project description) and establishing a weighted average elevation of the topo line at each point. Read the readme document for more information. DB03-1 Topography Data with event data This folder contains cleaned up elevation data from the DB03-1 experiment, plus aggradation and erosion event data. The main folder contains the elevation and event data workbooks: one Excel workbook per run day, and three sheets per workbook corresponding to the three topo lines, plus worksheets of event counts and durations. All elevation data is in pixels-above-bottom-of-image. The data was collected by analyzing images of laser lines (see project description) - note that the laser-line images were all corrected based on the calibration grid for the middle (x=1.75 meters) line, which may introduce minor errors in the data for the other two lines. In addition to the basic elevation data, the workbooks contain Event data (Aggradation and Erosion) for each day, plus the Excel macros that created the event data There are two workbooks with combined results - see the readme file. DB03-2 Final Deposit Images These images are composite images of the deposit. For each cross-stream transect, a series of overlapping images were taken, and these were stitched together to create these composites. The original images are elsewhere in this archive.

Abstract: NCED is currently involved in researching the effectiveness of anaglyph maps in the classroom and are working with educators and scientists to interpret various Earth-surface processes. Based on the findings of the research, various activities and interpretive information will be developed and available for educators to use in their classrooms. Keep checking back with this website because activities and maps are always being updated. We believe that anaglyph maps are an important tool in helping students see the world and are working to further develop materials and activities to support educators in their use of the maps. This website has various 3-D maps and supporting materials that are available for download. Maps can be printed, viewed on computer monitors, or projected on to screens for larger audiences. Keep an eye on our website for more maps, activities and new information. Let us know how you use anaglyph maps in your classroom. Email any ideas or activities you have to email@example.com Anaglyph paper maps are a cost effective offshoot of the GeoWall Project. Geowall is a high end visualization tool developed for use in the University of Minnesota's Geology and Geophysics Department. Because of its effectiveness it has been expanded to 300 institutions across the United States. GeoWall projects 3-D images and allows students to see 3-D representations but is limited because of the technology. Paper maps are a cost effective solution that allows anaglyph technology to be used in classroom and field-based applications. Maps are best when viewed with RED/CYAN anaglyph glasses!

Title: Illgraben bedrock erosion samples
Persistent ID: http://doi.org/10.5967/M0XG9P4P
Abstract: Erosion marks on marble and granite bed samples in the Illgraben Torrent (2006-2007). When studying bedrock erosion by a debris flows event, rarely do we know the detailed initial topography of the bedrock channel. This makes it impossible to measure the volume loss due to single debris flow events. To overcome this challenge, we placed initially flat stone samples of marble and granite in the Illgraben torrent, Switzerland, a location frequently scoured by natural debris flows. At the Illgraben, there are typically several events per year, due to the high availability of source material in the upper catchment that fail during summer rain storms (e.g. McArdell et al., 2007; Badoux et al., 2009, Berger, 2011). The stone samples captured groove and impact marks on the stone samples caused by the debris flows.

Title: William Brownlie Alluvial Channel Data
Persistent ID: http://doi.org/10.5967/M0028PFT
Creator(s) National Center for Earth Surface Dynamics
Abstract: In recent years, attempts have been made to develop numerical models for unsteady flows in channels with sediment transport. This work was conducted to analyze two essential ingredients of any numerical model: the relationship between the hydraulic variables (slope, depth, and velocity), and the predictor of sediment concentration. Report KH-R-43A (not in this archive) presents a detailed analysis of the two components and examines their role in numerical modeling. Six hydraulic relationships and 13 sediment concentration predictors are examined and compared. New relationships are then developed which appear to be more accurate than the existing techniques. Finally, the new relationships are utilized in a numerical unsteady flow, moveable bed model which uses a four-point implicit finite difference solution scheme. The data base associated with this report (presented originally as Report KH-R-43B) contains 7,027 records (5,263 laboratory records and 1,764 field records), in 77 data files. The data are provided here as two spreadsheets â€“ field data and laboratory data. Not all records were used in the final analyses, but they have been included in an attempt to provide a historically complete set of alluvial channel observations. The material presented in these reports is essentially the same as the thesis submitted by the author in partial fulfillment of the requirements for the degree of Doctor of Philosophy. A common list of references, with data sources separated from other references, has been included in both reports.

Title: Eel River Flipchart
Persistent ID: http://doi.org/10.5967/M07S7KRN
Abstract: This is a 34 page flipchart of the Angelo Reserve. Each page is an 8.5x11 map of a river segment. The maps show the location of the highest accumulated streamflow (using DEM) as the river, even though the channel is wider, and use the vegetative canopy DEM colored by vegetation height. Note the decision to use canopy instead of the traditional bare-earth is to provide visual references while out in the field. Bare-earth provides little help when maps are zoomed in this close. Laminated versions will be availible at the ACCR Science Center to be used during field sampling. Sampling sites can be drawn directly on the maps with a sharpie then removed later using alcohol. Marked up maps are to be either copied using the xerox machine, or scanned. Scanned versions can be sent to Collin Bode to convert the points into a GIS coverage.
Title: Eel River Steelhead Study
Persistent ID: http://doi.org/10.5967/M0125QK6
Creator(s) Power, Mary E.
Abstract: Throughout the world, historically large populations of native anadromous salmonids are in severe decline or extinct. In the United States alone, twenty-six Evolutionarily Significant Units of Pacific salmonid are currently threatened or endangered. These declines are most commonly attributed to degradation of spawning and rearing habitat resulting from increased loading of fine sediments. Although excessive loading of fine sediments into rivers is well known to degrade salmonid spawning habitat, its effects on the demographically critical rearing juveniles have been unclear. We experimentally manipulated fine bed sediment in a northern California river and examined responses of a juvenile salmonid. Increasing concentrations of deposited fine sediment decreased growth and survival of juvenile steelhead trout. These declines resulted from a shift in invertebrates toward burrowing taxa unavailable as prey and from increased steelhead activity and injury at higher levels of fine sediment. The relationship between deposited fine sediment and juvenile steelhead growth is linear. This suggests that there is no threshold below which exacerbation of fine sediment delivery and storage in gravel bedded rivers will be harmless, but also that any reduction will produce immediate benefits for salmonid restoration.

Abstract: Cantelli, A., Paola, C. and Parker, G., 2004, Experiments on upstream-migrating erosional narrowing and widening of an incisional channel caused by dam removal, Water Resources Research, 40, W03304, doi:10.1029/2003/WR002940 The present paper reports on a laboratory investigation of the erosion of a deltaic front induced by the removal of a dam. We built a laboratory model of a dam, and observed both the sedimentation in the reservoir due to the downstream propagation of a delta front and the erosion of the delta front during dam removal, including measurement of channel morphology and flow field. Based on an analysis of bank erosion two principal erosive trends were detected: during the initial stage of erosion the width of each section quickly decreased to a minimum value, after which the section widened. Undistorted Froude similitude is used to scale the results up to field dimensions.

Title: Density Current Confluence Velocity Data
Persistent ID: http://dx.doi.org/10.5967/M0WH2N0V
Abstract: Data collected and processed by H. Ismail et al during density current confluence experiments at the University of South Carolina Hydraulics Lab (2013-2015). In all files, x, y, and z denote down-stream, cross-channel, and vertical coordinates, respectively. The origin is the upstream junction point on the flume bed. u and v denote velocity in the x and y directions, respectively. U and H are depth-averaged velocity and current thickness, respectively. "vertical-profiles-u.xlsx" contains down-stream (u) velocity versus distance from the bed at 9 locations along the main channel centerline. "horizontal-u.xlsx" and "horizontal-v.xlsx" contain measurements of down-stream (u) and cross-channel (v) data at 3000 data points located on five horizontal planes in the vicinity of the junction in the main channel. "layer-averaged.xlsx" contains computed depth-averaged velocity and current thickness for each profile defined by the data in "vertical-profiles-u.xlsx".
