The invention belongs to the technical field of water resource management, and in particular relates to a method for regulating the operation process and identifying risks of a water network water resource system. It is characterized in that, based on real-time perception information, it provides irrigation water demand information for the regional multi-water source optimal allocation model, and the real-time water allocation decision-making model determines the real-time water demand; the medium and long-term runoff forecasting model is used to predict the monthly runoff of the watershed in the future; downscaling climate The model provides input for the short-to-medium-term hydrological forecasting model; the groundwater simulation forecasting model is used to regulate the groundwater level; the multi-water source optimization dispatching model for coupled forecasting combines all the above-mentioned information to realize joint dispatching of multiple water sources; the multi-water source dispatching model provides daily runoff water allocation decisions, Water delivery is carried out through the water resource transmission automatic control unit to achieve precise distribution. The technical scheme of the invention can be widely applied to the management of water resources in river basins (regions), especially the high-efficiency utilization of water resources in irrigation districts. The provided method has clear implementation steps and is easy to implement.
Description
[0001] Patent field [0002] The invention belongs to the technical field of high-efficiency utilization and management of water resources based on a network of water networks, and in particular relates to a method for regulating the operation process and identifying risks of a water network water resource system. Background technique [0003] Water resources and their efficient use are issues of widespread concern around the world. At present, my country's water resource utilization efficiency is low, and water shortage and water waste coexist. The utilization efficiency of agricultural irrigation water is only 40% to 60%, which is far lower than the 70% to 80% in developed countries; the benefit of water resources (unilateral water GDP) is only 1 / 5 of the world average. Therefore, the improvement of water resource utilization efficiency, especially the efficiency of agricultural water resources, has become the key to ensuring my country's water security, food security and e...
