Abstract:
In the context of global climate change and rapid development of economy, the contradiction between water supply and demand was sharpening. The project of Interconnected River System Network (IRSN) can change the connectivity of nature water system to develop the large-scale and inter-basin water resources allocation framework, redistribute water resources in time and space, and then realize the multi-source complementary and high and low water adjustment, therefore IRSN strategy has become a new approach to solve the water resources allocation issue in China. Compared with the traditional water resources allocation, water resources allocation base on IRSN emphasizes the inter-basin water resources utilization, which involves a larger area and benefit group. Based on the characteristics and principle of the water resources allocation through IRSN, a new water resources allocation mode - Rights Protection and Balanced Development Mode is proposed in this paper, and the main techniques and methods of water resources allocation through IRSN are discussed, including the inter-basin water cycle simulation, analysis of synchronous-asynchronous encounter probability in the water division area and intake area, and the calculation method for available water supply in the water division area.
