The purpose of this study is to consider sediment deposition in large reservoirs with high suspended sediment inflows. A characterising feature of this kind of reservoir is the existence of turbidity currents due to density differences between inflow and ambient waters of the reservoir. Therefore, two major parts can be found in this study: firstly, experiments and analysis of the …

This paper will focus on the erosion (soil loss) portion of the study. A total of 15 study plots were created at the site. All plots were seeded with Elymus glaucus (blue wild rye), a local native grass, at a rate of 40#/acre. A total of 12 different blankets were installed in October 1998 by Shasta College faculty and students.

The deposition rates of suspended cohesive sediment and the patterns of bed erosion have been studied to a lesser extent. For the experimental range the erosion rates were found to be independent of the shear strength of the bed and the concentration of suspended sediment. They depend strongly on the bed shear stress.

In this study, we investigated sediment delivery during rill erosion in purple soil. We used the volume-replacement method to measure the volume of eroded soil and hence estimate the mass of eroded soil.
