Advance state-of-the-art in the use of acoustic techniques to characterize fractional rates of suspended sediment and bedload transport, relate acoustic signatures to properties of sediment loads and sediment deposits behind dams, and soil piping and pore water content in embankments. Utilize physical models and field sites to evaluate and develop key relationships related to sediment transport, deposition behind earthen spillways and embankment erosion. Data from experimental studies and from the literature will be used in the development of predictive tools of the spillways and embankment erosion process. Collaborate with other ARS locations, the National Center for Physical Acoustics and the National Center for Computational Hydroscience and Engineering at the University of Mississippi, and other university cooperators to meet the research objectives.
