摘要

应用Green-Ampt修正方程及运动波方程，构建了天然降雨条件下的黄土区均匀坡面水文预报模型，并利用野外天然降雨径流实测资料进行了验证。结果表明，总径流量预报相对误差在20%以下，预报径流过程与实测径流过程吻合很好，坡面水文模型可以较好地模拟黄土地区天然降雨条件下的均匀坡面水文过程。同时也指出，应深入研究复杂坡面上的水文预报模型，进一步完善黄土区坡面水文模型。

Abstract

Applying modified Green- Ampt equation and kinematic wave equation and using observed rainfall and runoff dat a

hydrology model of uniform loess hillslope was built up and validated. Results showed thatrelative effor ofrunoff volume was under 20% and predicted runoff ydrograph accorded well with observed runoff hydro-g raph

which means thathy drology model on loess hillslope broug htout by this thesis can be used in simulating hy-drology processes produced by natural rain on uniform loess hillslope. Atthe same time

it was pointed out thathy-drology predictiveon model of complicated hillslope should be studied and thathydrology model of loess hillslope should be improved.
