the flood control of reservoir

Flood control requires the reservoir maintain low levels of water to allow for the inflow of flood waters, while power generation requires high levels of water in the reservoir.

抵御洪水需要水库保持低水位运行，以容纳洪水的流入，而水库只有保持高水位才能满足发电的需要。

Combined with precipitaton forecast and flood forecast, the upper bound ofdynamic control on limit water level of Huanren Reservoir in flood season was determined.

在此基础上，联合降雨预报和洪水预报确定了桓仁水库动态控制汛限水位的上限。

The paper explains even the environmental evaluation content of reservoir dam, flood control project, irrigation and drainage project.
