Abstract

This paper describes the application of the revised parabolic transmissivity profile form of TOPMODEL, leading to a second-order hyperbolic base flow recession curve, to four years of 18 minute data from the 36 ha Ringelbach research catchment in the Vosges, France. The model is completed by evapotranspiration, snowmelt and runoff routing components. As far as possible the parameters of this form of the model, or their ranges, are estimated a priori. Results are given that compare the original and revised forms of TOPMODEL, with and without optimization. One particular feature of this catchment is the availability of measurements of saturated areas. These are taken into account by using a modified distribution of the soil-topographic index, in a first attempt to relax the assumption of uniform transmissivity in the catchment. It is shown that the reasonably good results obtained with the original model are improved with the revised model, particularly in the simulation of dry weather flows, and that further improvements are obtained with the modified soil-topographic index distribution.
