Researches for urban rainfall-runoff simulation are inseparable from the hydrological information. However, this information is always composed of large amount of multi-source and heterogeneous data, which will bring significant difficulties to the information organization and management systems. In this paper, Geographical Information System (GIS), a specialized information system for the spatial information is introduced into the studies of urban rainfall-runoff simulation (URRS), in which a series of applications are presented. In these applications, hydrological information in urban region is collected, stored and processed by the spatial data storage, analysis and visualization abilities of GIS. The applications show that the integration of GIS and hydrological information is feasible in URRS and has achieved remarkable results, which can provide a strong data support to the simulation and control of urban storm water disaster.
