Abstract

A simplified theoretical model of storm runoff has been combined with analysis of rainfall records to improve understanding of dryland runoff processes in the Guadalentin catchment of SE Spain, and in particular the decrease in runoff fraction with increasing slope length or catchment area. A modified Green-Ampt equation is applied here to give storm runoff estimates for conditions of constant effective rainfall intensity. The rainfall data can then be combined with a Hydrologically Similar Surface (HYSS) analysis of the soil/land use response, and analyses of catchment network morphology and connectivity to forecast the heterogeneous distribution of ephemeral stream runoff
