Study of combined flood control forecast operation manner and limited water level in reservoir group;

The present article aims to introduce the authors research on the method of flood control forecast operation a reservoir can actualize in a flood season.

To improve the floodwater resources utilization by the reservoir operation and the researching reservoir flood regulation method considering rainfall and runoff forecast information,an operation chart for reservoir flood control is put forward by using 3-hour flood forecast information on the basis of analyzing flood course and reservoir flood control characteristics.

To develop the multi-reservoir flood forecasting and dispatching system that has high generality and strong extensibility, the difficulties are the design of architecture, the integration of multi-reservoir and alternative management, making alternative lack of rainfall data, real-time co-correction, future flood situation analysis, multi-reservoir operation and decision-making and so on.

WebGIS based Basin Flood Management System is an advanced high technology based platform for supporting the large river conservancy commission in flood forecasting and warning,emergent operation of flood works,flood damage assessment,flood water utilization,and decision making for flood fighting.
