R‐5 revisited: 2. Reevaluation of a quasi‐physically based rainfall‐runoff model with supplemental information

In this paper a new set of infiltration data for a small rangeland catchment, described in the companion paper (Loague and Gander, this issue), is used to reexcite and reevaluate a quasi‐physically based rainfall‐runoff model that was previously tested by Loague and Freeze (1985). The rainfall‐runoff model is an event‐based simulator of the Horton overland flow mechanism. The performance of the model is shown to be somewhat improved in this study with the supplemental information over the original study. However, the model does not fully approximate the rainfall‐runoff processes for the catchment, a combination of Horton and Dunne overland flow, and therefore the new data do not lead to an overwhelming improvement in the model performance.
