Abstract:

Distributed hydrological model is currently the hotspot of watershed model research. In this research, the data storage, physical realization and message communication of distributed hydrological model in Web-based GISframework are discussed through integrating distributed hydrological model with Web-based GIS technology. A complete scheme of integrating distributed hydrological model with Web-based GIS is designed, based on which the network computing service of CREST (Coupled Routing and Excess Storage) model is accomplished. The results suggest that the integration of distributed hydrological model and Web-based GIS technology expands the scope of the application of distributed hydrological model.
