Description

technical field [0001] The invention belongs to the technical field of water conservancy project dispatching and numerical simulation, and in particular relates to a numerical simulation method for coupling engineering dispatching and pollutant transfer process of a tidal river network. Background technique [0002] The Pearl River estuary area is a region with rapid economic and social development in China, and has a pivotal strategic position in my country's economic construction. With the rapid development of social economy, the problems of water environment pollution, water supply safety, flood control (tide) and drainage in the Pearl River estuary area are becoming more and more prominent. The main factors causing these problems are excessive / insufficient hydrodynamic force and tidal river water body wandering back and forth. . Using sluices, pumping stations and other water conservancy projects to regulate the hydraulic regulation of tidal river networks is a key meas...
