英文摘要	Hydrological forecasting in semi-arid and semi-arid areas is always the focus problem for hydrologists, and the watershed hydrological model is an effective tool for simulating and forecasting hydrological processes. The double excess watershed model (DEWM) was proposed by the Chinese hydrologists in Shanxi Province and was widely used in local reservoirs. Practical application of reservoirs for many years shows that there exist certain problems in the structure of model. Therefore, we modify the structure from three aspects: 1.Employ new infiltration formulas, 2.Simplify filling container structure and proposes a curve of the underground infiltration capacity, 3.Modify the evaporation simulation. Floods of Zhangfeng reservoir are used to verify the applicability of the modified model (MDEWM). Use the SCE algorithm to calibrate the model parameters. and compare the flow processes of calibration period and validation period with the measured values respectively. The flood peak pass rate are 83.3% and 91.7% in calibration period, and peak current are 50% and 100% in validation period of MDEWM, which results arc better than DEWM or equal to it, The research of this article can provide a certain theoretical significance and practical value for flood forecasting, reservoir scheduling and water management in semi -arid and semi- humid areas,
