Study And Application Of The Model Of Real Time Monitor Decision Support System For Water Amount And Water Quality Of Taihu Basin

To know the information of water amount and water quality is the key to carry out rationally exploiture and protection of water resources. Therefore, it is very indispensable to real-time monitor water amount and water quality and to develop decision support system of water amount and water quality in order to manage and protect water resources effectively. Our country began to investigate the decision support system of water resources since the 1980's, but there isn't a decision support system whose core is the optimal arrangement and management system will serve the turn of the whole country because of the range of the system development was limit in certain area or river basin and the research of water resources decision support system which is based on the real time monitoring of water amount and water quality is still on the elementary phase, especially in the area of plain river net. The research of decision support system of water resources in developed countries is earlier than our country. They have set up comparatively self-contained decision support system using modern information technique and obtained tremendous social economic benefit.In this thesis, hydraulic model and water quality model was respectively established by IWRS for Wangyu river. They read the data which stored in system database and the telemetry data which is manually imported automatically, and compute water information in system by using the RS2000 which is the key process of IWRS after dealing with these data. Water quality simulation run at the same time based on the hydraulic simulation. Then the real time monitoring decision support system will be set up by using FloodWorks combined with IWRS for Wangyu river. This system will carry out real time monitoring at every observation station to obtain the water information and pollutant information, and forecast the water information and pollutant concentration based on the hydraulic model and water quality model which have been set up.
