Description :
This study investigates the effect of rainfall intensity (RI) and soil surface cover on losses of sediment and the selective enrichment of soil organic carbon (SOC) in the sediment by surface runoff occurring under different RI and soil surface cover percentages. The AA. also tried providing an insight into the temporal changing patterns of sediment, nutrient discharge and changes of sediment particle size distribution as well as their relationship in order to better understand the dynamic pattern of nutrient concentration and load. They hypothesize that increased residue cover and decreased rainfall intensity will reduce soil and organic matter loss in runoff. Results of the laboratory rainfall simulation experiments and discussion.
