Discussion on hydrological forecasting technology in the Qinhuai River Basin based on a general model platform
The Qinhuai River Basin is located in the lower reaches of the Yangtze River,with mountainous areas in the upper reaches,plains in the middle,and tidal river networks in the lower.The trunk and tributary rivers in the basin are connected by veins,and there are numerous water projects such as reservoirs,enclosure region,dams and floodgates making rapid online rolling flood forecasting challenging.Based on the intelligent decision-making system platform for the early warning and regulation of flood control and drought relief in Jiangsu Province,this paper studies various general models and algorithms such as rainfall runoff,flood routing in river sections,and reservoir flood regulation,which can consider the influence of large and medium-sized reservoirs in the upper reaches of the basin and their scheduling impact,divide the distributed forecasting unit suitable for the characteristics of the Qinhuai River system,and construct and propose a flood forecasting model which is verified by the heavy rain and flood event in July 2024 with the control section of Qiancong Village.The results show that the online general model algorithm can realize the construction of rapid flood forecasting scheme and its simulation calculation with good accuracy,and can provide strong technical support for flood forecasting and scheduling decision-making in the Qinhuai River Basin.
