SIMULATION ON SLOPE RUNOFF AND SOIL EROSION IN A RAINING EVENT
坡面降雨径流和土壤侵蚀的数值模拟

The paper deals with the model of runoff and erosion in slope land. The solution to the one dimensional hyperbolic runoff equations and sediment equation are obtained respectively by using the characteristics method and finite difference method. The simulation calculations were conducted for real rain processes and compared with experimental data of field test. The results show that the model and the program are reasonable and practical, and they are useful in the study of the soil erosion.
