T1 - Towards the use of catchment geomorphology in flood frequency predictions
AU - Beven, Keith
PY - 1987
Y1 - 1987
N2 - A further development of a topography‐based model of catchment hydrology (TOPMODEL) is described and applied to the problem of predicting flood frequency characteristics. The model can simulate infiltration excess, saturation excess, and subsurface runoff contributions to peak flows. Catchment geomorphology plays a central role in predicting the nature of the hydrological response. Using stochastic rainfall and initial condition inputs based on measured data, the model satisfactorily reproduces the mean hourly flow flood frequency growth curve for the Wye catchment, but not the mean number of peaks greater than 3mm h−1 each year. Suggestions for further improvements are made.
