Caribbean Migrations' foundational Jamaica Returned Migrants Study (CM-JRMS) is the first of a broad programme of research to be developed, exploring the health, well-being of people from the Caribbean and Caribbean Diaspora. For the Jamaica Returned Migrants Study, rigorous behavioural science methods were used to collect data on the psychological, social, and health issues associated with the diverse patterns of migration that Jamaica and the broader Caribbean is experiencing - types that are not recorded in traditional migration literature that tends to focus on longer periods of residence in countries.
Water motions at the shoals of Cape Canaveral were measured. Several acoustic Doppler current profilers (ADCPs) were located during thirteen deployments intermittently between September 2013 and September 2016.
This is a page for the the delta flume at the Earth Surface Dynamics Laboratory at the California Institute of Technology, where a long narrow section flows into a large ocean basin. Here, we build deltas with subcritical flow and backwater lengths of ~1m. Sediment & water feed rates are precisely controlled at the upstream end of the narrow section such as to build a normal flow reach in the river section with a specific depth (~1cm) & slope (~3e-3). Water level in the basin is controlled with an adjustable weir at the far downstream end of the basin. We use overhead cameras to create a timelapse planform delta evolution, & laser & ultrasound altimeters to measure bed & water surface topography.
The Eel River CZO is a multi-disciplinary research collaborative based at the University of California, Berkeley. Our research focus it to explore how biotic and abiotic factors interact in the near-surface environment (from bedrook to tree tops) and how these relationships impact environmental processes.
The Sediment Experimentalist Network (SEN) aims to to facilitate broad collaborations within the Earth-surface community to determine, address, and promote responses to our needs as scientists and educators for best practices in experimental methods and in the storage, archiving, and dissemination of experimental data.
This project space includes data from a set of flume experiments run in 2014 at Arizona State University investigating sediment transport and turbulent structures downstream of a 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. Sediment transport data was 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 was also recorded to refine fluid velocity measurements.
Data included in the this project space includes:
(1) Raw bedload images
(2) Raw PIV images
(3) Processed PIV .csv files
(4) Sediment transport .csv files
(5) Sediment time series (both downstream and cross-stream) .csv files
(6) Sediment Tracking Videos
