A simple model for flow on hillslopes

A simple hillslope hydrological model predicting water movement on sloping shallow soils is developed. Unlike existing hillslope models, the new model can be used to predict flow for long records of climatological data and it can be easily extended to include preferential flow. It compares favorably to other models with more restrictive input requirements. Its application is illustrated for experimental data collected for an homogeneous hillslope at the Cooweeta Hydrological Laboratory.
