摘要: GAMES, the Guelph Model for evaluating effects of Agricultural Management Systems on Erosion and Sedimentation, has been developed as a screening tool watershed management. The basic philosophy behind model is estimation soil erosion by Universal Soil Loss Equation percent field loss delivered to downstream fields stream micro-delivery ratio function which incorporates surface roughness, land slope, hydrologic condition length overland flow path. accommodates spatial units variable size shape. time frame separates seasonal changes in erodibility, rainfall characteristics management conditions. output generated each within are potential erosion, rate, delivery adjacent field, stream, sediment load yield rate. application small agricultural shows fluvial sources and...
