Abstract
Based on the equations of continuity and motion for sediment transport and the dynamic equation of spatially varied open channel flow, a computer simulation of erosion is developed. The water source for the erosion simulation may be rainfall or snowmelt. To provide snowmelt a computer simulation giving the rate of snowmelt from limited climatic data has been adapted to work conjunctively with the erosion model to provide a dynamic solution to erosion and overland flow, from precipitation and other limited climatic data. The computer simulation model has been tested using climatic data at and near the phosphate mine in Southeastern Idaho and calibrated from Forest Sciences Laboratory field erosion plot data at a spoil dump at the Wooley Valley Mine area. Good agreement exists between the erosion predicted by the model and the measured amounts over a season’s time, but not on an individual storm, or day of heavy snowmelt basis.
