摘要

The mode of mixed runoff yield with runoff yield under saturated storage and under excess infiltration has been brought forward, according to great varieties of the precipitation distributed both in the time and space, flood level quick rise and fall in the arid and semi-arid area, that the characteristic is different with the wetness and semi-wetness area. The double excess runoff yield model that is runoff yield under excess infiltration and the soil moisture under excess saturated have been developed based on the models of both domestic and overseas. At the same time the paper has made suggestions to enhance the planning and constructing of the rain gauging station net, and establishing reasonable hydrological station net to meet the need of making flood forecasting project, parameters calculation and flood forecasting. The paper also has been suggested to increase the simulation unit of runoff yield and concentration flow in order to more rationality and veracity.
