| Abstract: | Based on the conventional hydrological computation and the latest digital hydrological model, in this paper, the digital catch- ment production, space analysis and policy-making process are integrated into the information computation flow. Then, the key technolo- gy and theory of application of the geographic information system in the hydrological design are described in terms of the extraction of the catchment characteristics of catchment area, river length, storage capacity curve, etc. , building of the digital catchment model and map- ping of isoline, and selection, planning and simulation of 3D panoramic site. It expects that the study in this paper can provide catchment planning, engineering design and flood predication with new concept and basis. |
