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. TDB_15_2_BasinDimensions.png shows the dimensions of the experimental entrance condition, and orients the coordinate system. TDB_15_2_RunTimeConversions.xlsx shows the conversion between run hours and run cycles.
