Abstract
Soil losses from a level surface of four Illinois soils under simulated rainfall were measured in the Hydraulics Laboratory of Agricultural Engineering Department of the University of Illinois at Urbana-Champaign. Several variables affecting soil loss have also been measured, including soil moisture content, bulk density of compacted soil sample, soil aggregate stability; and basic variables for calculating rainfall energy (i.e., raindrop fall velocity, drop size and distribution). Based on these results, the mathematical relationships of soil loss as a function of kinetic energy for Tama, Catlin, Cisne and Plainfield soils were developed. A general prediction model of raindrop erosion as a function of kinetic energy, as a function of kinetic energy and soil clay content, and as a function of kinetic energy and organic matter content are proposed.
