Develop methodologies to quantify soil surface boundary conditions and erosion processes.
Current Research Projects: Develop sediment mass balance relationships and revise current erosion process model concepts.
Develop sediment mass balance relationships and revise current erosion process model concepts.
Development of a Multiple Box System:
Single-sized plot box or field plots:
Qs = Fn (Rain, Runoff, Slope,
Surface condition, etc..)
"Total sediment delivery"
Multiple boxes or field plots of different lengths:
Qs(x) or d(Qs)/dx
"Erosion / deposition processes
occurring on the surface"
Erosion by an interrill-type surface scour. Sediment regime is detachment limiting due to high soil strength or low soil erodibility.
Severe rilling occurred. Sediment regime is transport limiting due to low soil strength or high erodibility.
