| Abstract: | The Yellow River Delta area is located in the east of sandong Province east of China. Floods in this area are caused by two hydrological conditions. One is the rairstorm in the late summer and early fall, and another is the ice run in the winter. In the past more than 130 years, the floods happened about fifty times (including serious ten times) in the delta area. The flood risk will continuosly exist if the water and ice regimet and silt deposit can not be changed basically. So the WIRWIS has been established by using ARC/INFO GIS. It is very important for developing agriculture, oil industry, and protecting ecologic environment in the delta area.The design of the WIRWIS is first topic. This topic describes a goal and application modules of the WIRWIS. According to the goal, the display module of maps and geo-data, the module of map query, the analytical module and the evaluation module of flood loss have been designed.The second topic is data organization. It is crucial for establishing database of the WIRWIS. So, the database is divided into some layers. They are terrain, water, Yellow River course, landuse, residence, oilwell, and factory etc. Each layer stores only one type of geographic information and related attribute information. In this way it is easy for maintaining and using.The third topic is the establishment of the WIRWIS method. Data collection is a basic step of this topic. By using ARC/INFO GIS, all geographic and stat istical data have been input into-the computer. In order to build the database, geographic attribute information has also been input after coverages (files in ARC/INFO) processed.Finally some application study has been done. From a 3-D DTM the best flood discharge route has been found. After a flood discharge zone created, submerged loss can be evaluated. So a rescuing plan can be made soon. |
