Abstract :
This study uses remote sensing and raster GIS technology to establish a network-based hydrologic modeling system. The key phase of the model is built on IBM personal computer with WINDOW platform (as client) and networked with workstation system (as server) through computer networking. The basic framework is to extract hydrologic parameters via computer networking from a watershed geographical database and the HEC-1 input data file can then be constructed automatically. Finally, by routing from the upper subwatershed to the outlet for various rainfalls, the output runoff hydrographs can thus be produced
