Start Date: Sep 01, 2013
End Date: Aug 31, 2018
Develop and execute novel experimental programs to understand the processes leading to the initial growth and development of rills and gullies under varying hydrologic and topographic conditions. Define the key pedologic, hydrologic, and hydrodynamic parameters that control the magnitude, morphology, and rate of soil loss, gully erosion, and landscape degradation due to gully development. Develop theory and equations to predict soil loss and gully erosion on hillslopes and agricultural fields under different management practices and integrate these into USDA watershed and soil erosion models.
