Predicting Particle-Size Composition of Eroded Soil

ABSTRACT ASET of equations was developed for predicting particle-size distribution of eroded soil, based on soil surface area and texture and con-sidering organic matter enrichment and the tendency of a soil to rill. Three parameters—particle-size distribution of the matrix soil, organic matter, and water content at -15 bars pore pressure gave a good estimate of the expected particle-size distribution.
