The Design And Achievement Of Prefectural Mountain Flood Disaster Warning System Which Is Based On WebGIS

Mountain flood as a geological disaster occurs very frequently and badly in our country.Mountain flood, debris flow and landslip are caused by the rainfall in each year. It not onlythreatens the safeties of our lives, but also restricts the economic developments of the massifareas. It’s difficult for us to prevent those torrential floods because of its multiple, randomnessand destructiveness. In China, the rainstorm-areas, flood-areas and living-areas are alwaysoverlapped, it makes the loss of national lives much more severe.To build a Mountain floodmonitoring and warning system is the most important part of the Non-engineering measuresof Mountain flood disaster defense.In this dissertation, the summaries of Mountain flood disasters have been introduced.The implementation methods of the WebGis technique has been summarized through theresearches of the Mountain floods disaster prevention-control and the warning systemconstruction presented both by domestic and overseas. A system which is provided withMountain floods database, the application software of the prefectural monitoring and warningplatform, phone-fax warning issue, system integration and some other functions have beenbuilt completely based on the SuperMap IS.NET platform which belongs to SuperMapSoftware Co. Ltd. It includes advanced computer methods, the RIA （Rich InternetApplication） and Remote Sensing technologies, the professional functions of the flash floodwarning, the combination architecture of B/S and C/S systems.The system aims at the need of the Mountain flood disaster prevention and control, itachieves the real time monitoring, Internal warning, warning issued, emergency response andother functions. Additionally, the system provides the ports to the corresponding monitoringand warning equipments, it makes the system could connect with the remote-measuring andwarning system of rainfalls, reservoirs and dams. The system Improves the veracity and thetimeliness of the monitoring inquires, the transmission sharing and the warning analysis of theMountain floods disaster data. It also improves the decision rationalitiy of Mountain floodsdisaster defense. It provides more accurate flood informations to governments, flood controlheadquarters and disaster reduction organization. The system helps them to make the correctearlier decisions and the earlier arrangements before the terrible flood calamities occur. Mountain flood...
