Design and Development of GIS-Based Distributed Hydrological Model System |
|
| Abstract: | In recent years, alona with the development of computer science, Geographic information systems (GIS) and Remote sensing (RS) technology, the study of Distributed Hydrological Model (DHM) has also made quick progress. First the applications of GIS in DHM were introduced, and four different approaches widely used to integrate GIS with DHM were addressed. Based on the analysis of the advantages and disadvantages of these approaches, the author developed the GIS-based Distributed Time Variant Gain Model (DTVGM) system by coupling mechanism of water cycle with system theory, which integrate GIS and DHM by means of loosing coupling. The system was proved valid and efficient by the case study in Gansu province Banqiao basin. |
