摘要：

This paper presents a methodology to study the amount of information on spatial heterogeneity present in hydrological systems which is needed in order to obtain the best possible output of a rainfall-runoff model. Results of different runs of a distributed rainfall-runoff model, using different amounts of spatial information of a number of hydrological parameters and variables, are compared. Preliminary results show that for a 114 km(2) vegetated catchment in East-Flanders, Belgium, effects of spatial heterogeneity on catchment runoff are negligible. (C) 1999 Elsevier Science Ltd.
