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.
