禹门河水库死水位泄流规模论证

Demonstration of Discharge Scale Under the Dead Water Level of Yumenhe Reservoir

介绍了禹门河水库的基本情况,采用实测资料分析、造床流量计算、水库冲刷指标分析等方法,结合水工建筑物布置情况,对禹门河水库死水位的泄流规模进行了论证,最终确定死水位泄流规模为549 m3/s。采用该数值进行水库运用,有利于保持水库的有效库容,长期发挥水库的反调节作用。

Based on the analysis of the field data, calculation of the regime discharge and investigation on the scouring index, the Yumenhe Reser- voir was introduced and its discharging capacity at the dead water level was studied together with the consideration on the layout of hydraulic con- structions. The resulted discharging capacity is 549 m3/s. This discharging capacity has the benefit of maintaining the effective capacity and keep- ing the reregulation capacity of this reservoir for the long term.
