Real time flood monitoring system based on the technique of double close_loop

The paper presents the principles, functions and implementation methods of the real time flood monitoring system based on the technique of double close-loop control. In the practices of developing the Heilongjiang provincial flood control decision-making support system, a technical scheme of expanded double close-loop control is introduced. Based on this scheme, the functions of safety assessment for dams and dikes can be embedded into the real time flood monitoring system with an integrated GIS environment. The capability and practicability of real time monitoring, real time analysis and real time warning of the system is greatly enhanced, while the characters of real time, reliable and easy use are still ensured.
