黑龙江省拜泉县新义水库设计洪水推求

Xinyi Reservoir Design Flood Calculation of Baiquan County in Heilongjiang Province

新义水库位于黑龙江省拜泉县长春镇新义村,在乌裕尔河一级支流宝泉河上游,属于小(2)型水库,集水面积为5.30 km^2。根据附近流域水文站友爱站和克山站洪水实测资料,利用图集法,参证站参数修正法以及水文比拟法推求单站设计洪水及新义水库设计洪水,得出:流域面积<20 km^2的小(2)型水库设计洪水成果采用水文比拟法的设计成果。

Xinyi reservoir is located in Xinyi Village of Changchun Town in Heilongjiang Province,on the upper reaches of Baoquan River,the primary tributaries of Woer River,belonging to a small（ 2）type of the reservoir,and the collection area is 5. 30km2. According to the observed flood data about Youai station and Keshan station near the river basin,atlas method,reference station parameter correction method and hydrologic analogy method were used to calculate single station design flood and Xinyi reservoir design flood,the results show that the design flood results of small（ 2） type of reservoir with river basin area less than 20km2 are suitable to adopt the design results obtained by hydrologic analogy.
