Description :
Data for three representative storm events are described for a small 0.30 km2 erodible semiarid catchment. The mean grain size and sorting of sheetwash sediments were significantly different from fluvial suspended sediment for individual storm events. Sheetwash sediments were coarser and more poorly sorted than fluvial suspended sediments. Enrichment radios indicated selective erosion and transport of silt and clay, and preferential deposition of sands.
