Abstract: The dual drainage system and urbanization makes the study on urban flooding more complicated than that of rural areas. This paper reviews literatures on urban flooding study, discusses the methedology for urban flooding analysis and modeling, and puts forward a series of GIS approaches to these problems. It covers several GIS and hydrologic areas, e. g.,extraction of hydrologic parameters for urban areas, distributed rainfall-runoff model based on GIS grid model for urban areas, flood routing model, integration of hydrologic models and GIS, and visualization of urban flooding process using GL and Explorer modular. These metheds have been applied to the modeling of urban flooding process of May 3, 1994 in Sanming city, Fujian province.This study has achieved a satisfactory result and will be of wide application value and theoretical significance to urban flooding simulation, GIS system integration, and visualization of environmental processes.

Key words: Urban Flooding, GIS, Distributed Hydrologic Parameter Model
