Description

Technical Field

[0001] The invention relates to the field of water diversion projects, and in particular to a dynamic water diversion method for water diversion projects within a river basin. Background Art

[0002] Water diversion projects are a means for each river basin to balance water use. Water from water-rich areas is transferred to water-scarce areas to achieve inter-regional water balance and an important measure to solve the water resource demand in water-scarce areas. In the prior art, water diversion projects are generally divided into two types: one is a cross-basin water diversion project, and the other is a water diversion project within a river basin. Water diversion projects within a river basin generally involve areas with large basin radiation areas and complex water resource utilization. Compared with cross-basin water diversion projects, water diversion costs within a river basin are low. In view of the imbalance of water storage within a river basin, it is necessary to formulate and plan a detailed water diversion path. Generally, areas close to rivers in a river basin are easy to obtain water, and water can be easily supplied through some small tributaries and water seepage. However, for areas far away from the river basin, the supply of water by gravity is small, and often cannot meet complex water demand requirements. Therefore, it is urgent to propose a dynamic water diversion method for water diversion projects within a river basin. Summary of the invention
