Hazard research on reservoir flood limit water level adjustment by flood prediction model

Flood control forecast dispatch is a scheduling mode of flood resource utilization based on the preflood forecast information, Improved flood Criterion of original plan and Advance pre-discharge realization, thereby raising the flood limited level of the reservoir [1-4]. Since Flood forecast information exists forecast error, whether will the reservoir and its upstream and downstream flood risk increase after using Flood control forecast? Whether can the increased risk be acceptable? This is the key to the implementation of flood control forecast, but also the focus of attention of scheduling decision makers.
