ABSTRACT:
Detailed rainfall and runoff recorded information, from different plot sizes, constructed in natural hillslopes, was analyzed to obtain the “apparent infiltration” values. These values demonstrate an increase of the apparent infiltration rates at high rainfall intensity segments. The purpose of this study is to quantitatively understand runoff generation, on natural slopes, by combining detailed rainfall intensity information with surface characteristics, which are the main control of rainfall-runoff relations. The concept of looking at any unit area as a dynamic mosaic of contributors and sinks is the main idea of the proposed model. The model helped to explore sets of stable infiltration parameters, which depend mainly on surface characteristics and rain intensities. They varied little throughout the 2 years of the study. Measured and calculated runoff compared very well.
