Location: Watershed Physical Processes Research
Project Number: 6060-13000-029-031-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: Sep 16, 2023
End Date: Aug 15, 2027
Objective:
To develop regional and national relationships between legacy sediment stored in reservoirs and climate, landscape and reservoir attributes.
Approach:
Using a combination of echosounders determine sedimentation rates of reservoirs constructed as part of USDA Watershed Programs across a broad range of geographic, climate, topographic, land use, soil, and reservoir parameters following the procedure of Moriasi et al. (2018). Collect cores for grain size analysis, N and P concentrations, and sediment dating. Combine these new data with previously published studies (e.g., Bennett et al., 2013) into a comprehensive database of small reservoir sedimentation. Use this database to develop regional and national relationships between reservoir sedimentation and climate, geography, topography, soil, land use, and other parameters.
