摘要

The emphasis in this section is placed on two approaches that inevitably should be used in the study of runoff in urban areas, namely, the physically based modelling of the runoff process including the simulation of surface flow by solving mass and momentum conservation equations, and using GIS-based tools for preparation of good quality input data. Some results of originally developed tools based on GIS operations have been presented here. The advantage of the physically-based modelling over standard hydrological models is wider applicability of physically based parameters than those of the conceptual models. Obvious benefits of the GIS tools over the manual preparation of data are the time savings, high resolution and quality of information.
