Abstract

Flume experiments simulating concentrated runoff were carried out on remolded silt loam samples to measure the effect of rainfall-induced soil consolidation and soil surface sealing on soil erosion by concentrated flow for loess-derived soils and to establish a relationship between soil erodibility and soil bulk density. Soil consolidation and sealing were simulated by successive simulated rainfall events alternated by periods of drying. Soil detachment measurements were repeated for 4 different soil moisture contents. The results suggest that the compaction of thalwegs where concentrated flow erosion often occurs might be an alternative soil erosion control measure
