Abstract:Jinan Jin Xiuchuan Reservoir is a high-altitude mountain reservoir with insufficient infrastructure and great flood control pressure. To ensure flood control and the safety of public life and property, the Jin Xiuchuan Reservoir Service Office of Hydraulic Engineering Service Center of Jinan Municipality, together with scientific and institutions such as Shandong Huate Smart Technology Co., Ltd. and University of Jinan, has jointly built a digital twin platform for the Jin Xiuchuan Reservoir Basin. A preliminary "four-forecast" system for the basin has been formed, which has effectively improved the rainfall perception capability of the basin, realized precise dispatching of the basin, and optimized the flood control of the basin. This has shown significant benefits in promoting the coordinated progress of social economy.
