预报最小流量对于水利灌溉和水电站的管理运用具有十分重要的意义。特別是一个沒有水庫調节的水电站,如能尽早的預知最小流量及其持續时間便可以预知其最小出力,从而妥善的安排其运营計划。最小流量一般出現在没有地面徑流,河流依靠地下水补給的时候。在枯水季节由于讯后河川流量的递减趋势、降水量少,地面徑流几近蚔?每月的最小流量多发生在下旬。許多流域面积較小季节性的河 It is of great importance to forecast the minimum flow of water for irrigation and management of hydropower stations. In particular, a non-reservoir hydropower station, as early as possible to predict the minimum flow and its duration can predict its minimum output, so as to properly arrange its operating plan. The minimum flow generally occurs when there is no surface runoff and the river relies on groundwater recharge. In the dry season, due to the declining trend of the post-river flow, the precipitation is low and the ground runoff is almost 蚔 The monthly minimum flow occurs mostly in late. Many catchments are smaller seasonal rivers
