Real-Time Flood Forecasting and Regulation System of Poyanghu Lake Basin in China

Abstract

The design and development of Flood Forecasting and Regulation System (FFRS) is an important part of non-structural measures for flood mitigation, and Browser/Server (B/S) system based on WEB technology is one of the main directions of the system development. The framework of FFRS based on B/S system is introduced in this paper, which includes four levels, i.e. the database level, application support platform level, the application level and the user level. The framework can provide several functions, such as flood situation analysis, flood forecasting, flood regulation and system management, which has been used for the FFRS development of Poyanghu Lake Basin in China as technical support for decision making of local flood control. Currently, the system covers almost 102 flood forecast points and 37 reservoirs, for which flood forecasts and regulations are accessible online. This work would also be demonstration for other locations.
