Characteristics of Nonpoint Source Erosion from Burned Mountain Basin

Article Preview

Abstract:

A drastic change of hydrological characteristics of a deforested basin causes severe runoff, sediment yield, and environmental contamination. In these days, many forest suffered from more frequent wildfires than before due to the climate change and human activities in Korea. A bared soil surface caused by wildfires results higher peak discharge and serious erosion over the basin. Ultimately, the increased sediment erosion results the nonpoint source contamination of water and soils of the basin. Systematic researches on sediment yields had been carried out with a mountainous watershed which had been suffered from wildfires. The experimental watershed has being operated with six standard plots and one sedimentation chamber last four years. The cover management factor of RUSLE and the characteristics of SDR (Sediment Delivery Ratio) for burned mountain basin were suggested from the field investigation.
