The Xiaoqing River is an important regional channel and also a part of the layout of the “one vertical and three horizontal” inland waterway in Shandong Province.The restrictive factor of the re-navigation project of the Xiaoqing River lies in whether the shipping water resources can be guaranteed.Aiming at the problem of shipping water resources in the Xiaoqing River,this paper analyzes the current situation of water resources in the Xiaoqing River,obtains the guaranteed rate of 95% ~ 98% of the designed flow for many years,and then draws the conclusion that the existing water resources of the Xiaoqing River basically meet the requirements of water consumption of the supporting ship locks along the route by comparing the water consumption of ship locks along the route.Considering the uneven distribution of water resources in the Xiaoqing River within a year,in order to improve the navigation guarantee rate of the Xiaoqing channel and meet the multiple functional requirements of farmland irrigation and ecological landscape,a water replenishment scheme based on water diversion from the Yellow River and supplemented by the Dongping Lake was proposed,providing necessary technical support for the re-navigation project of the Xiaoqing River.
