Interrill Soil Erosion – Part II: Testing and Use of Model Equations
ABSTRACT LABORATORY measurements were made of interrill erosion as affected by varying overland flow discharge and slope steepness. Soil detachment and sediment transport capacity relations were then evaluated using experimentally obtained information. The model equations were utilized to further characterize interrill soil erosion. The overland flow region over which the model equations are applicable for a disturbed Nunn clay loam soil was determined from laboratory tests and critical shear stress analyses. The influence of slope length on interrill erosion was also examined.
