Research on Applying RS and GIS Technique in Big Reservoir Flood Prevention Control

摘要

In July, 2005, eighty-nine police soldiers died directly owing to one big reservoir dam collapse in a heavy rainstorm day in FuJian province, China. In 1975, the dam of ZuMaDian Reservoir collapsed, and then over 260 thousand people died. In 1979, the dam of Manzu2 Reservoir in India collapsed, and then about 5000 people died. In 1889, the dam American Johnston Reservoir collapsed, and then about 4000 people died. Frequently, it was supervisor's wrong reservoir flood prevention control that resulted in dam collapse. Reservoir flood prevention control is very complicated that it's necessary to apply information technique to support flood prevention control decision. Informationization of Big Reservoir Flood Prevention Control mainly includes the following contents: (1) acquiring basal reservoir data or flood data by full-digital photography and measure technique, remote monitoring, remote sensing, geographical information system, GPS, etc; (2) constructing digital reservoir flood prevention control management information system and three-dimensional virtual reservoir environment; (3) simulating and analyzing the scheme of reservoir flood prevention control based on massive history data analysis and scientific calculation according to professional reservoir flood prevention mathematic models; (4) providing flood prevention control suggestions for reservoir supervisor. By introducing the research and software development of "TingXi Reservoir Flood Prevention Control Management Information System", this thesis gives a detailed explanation about how to apply Remote Sensing and Geographical Information System technique in Big Reservoir Flood Prevention Control.
