General Functioning Design of Flood Control and Disaster Reduction System in Coastal City

In this paper,the importance of flood control and disaster reduction in coastal city is described.The general countermeasures of flood control and disaster reduction in coastal city and the basic task of flood control and disaster reduction system in coastal city are suggested.The general plotting of flood control and disaster reduction system in coastal city is designed in accordance with the purpose and principle of design of flood control and disaster reduction system in coastal city.The main functioning components of the system include eight subsystems,namely,GIS;information consulting;automatic measuring,forecasting,receiving and display of hydrometric and meteorological data;the forecasting of flood,warning and communication; the managing of reservoir,pumping statiom for waterlogging prevention and detention basin;legistration,execution and planning;emergency; water and soil conservation.The technical structure design of the system and the design of data base system,model base system and knowledge base system are described.
