Design And Implementation Of Tianjin Flood Preventing Decision Support System

Construction of flood preventing decision support system (DSS) in Tianjin is based on"the general plan of Tianjin flood preventing information system construction"and"the general plan and study of management software development and application for Tianjin water maneuvering center's water system projects". The purpose is to develop and apply advanced technology and study, adopt scientific methods, and with various display methods, accurately as well as vividly show river paths, reservoirs and gate stations'status and project graphs of the river net, which is located at the lower reaches of Haihe and is known as"lower reach of nine rivers"; to show real time data of raining and water status and real time graph of secondary planet nephogram; to provide scientific proof for leaders regarding modern project management, water resources maneuvering and flood preventing decision making; and to provide meeting coordination information service for directing organizations and water managing and water maneuvering departments'decision making.Tianjin flood preventing decision support system (DSS) is based on both abroad and domestic development experience of similar systems, starting on a high level and develop a most effective and suitable system with the shortest time, most reasonable investment with advanced technology. With application of this system, relevant leaders could be provided with scientific, obvious and accurate flood preventing rain, water, project status information and environment for their flood preventing directing, decision making and maneuvering; it can also provide advanced methods for Tianjin's flood preventing, water providing and water resource utilizing, maneuvering and management. It changes the traditional methodology on decision-making, applying computer communication and network technology into water system project's management, improving the level of modern management. This system is practically meaningful for Tianjin city safely going through flood period and water resources utilization. It can enhance effectiveness, advance forecast time, realize scientific maneuver and improve economic and social benefit at the maximum.Tianjin flood preventing decision support system is a systematic research and development of Tianjin flood preventing decision making information system. By application of various kinds of scientific methods and techniques, the research and development of the project established and integrated subsystems consists of comprehensive database of flood preventing information, reception and process of information, information enquiry and display, real time flood forecast of Ji Yunhe Canal and dispatch simulation, etc.
