Open publisher page 1 citations

Abstract

Applying modified Green-Ampt equation and kinematic wave equation and using observed rainfall and runoff data,hydrology model of uniform loess hillslope was built up and validated.Results showed that relative effor of runoff volume was under 20% and predicted runoff hydrograph accorded well with observed runoff hydrograph,which means that hydrology model on loess hillslope brought out by this thesis can be used in simulating hydrology processes produced by natural rain on uniform loess hillslope.At the same time,it was pointed out that hydrology prediction model of complicated hillslope should be studied and that hydrology model of loess hillslope should be improved.
