Abstract

The invention discloses a project scheduling and tidal river network pollutant transport process coupled numerical value simulation method. The method comprises the following steps of: establishing a tidal river network one-dimensional hydrodynamic force-water quality model; establishing a project application model to realize accurate and quantitative description of a project type and an application manner; solving the tidal river network one-dimensional hydrodynamic force-water quality model and the project application model by adoption of a finite difference format and a four-cascade solution; and establishing a gate pump group multi-target optimal scheduling model through aiming at targets of flood control, flood drainage and water quality improvement and project constraint conditions. According to the method disclosed by the invention, the accurate and quantitative description of interaction of a hydrodynamic process, a pollutant transport process and project scheduling is realized; and on the basis of simulating the project scheduling, the established gate pump group multi-target optimal scheduling model is utilized to obtain a gate pump group combined optimal scheduling scheme, so that the practical application value of the project scheduling simulation can be remarkably improved.

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...
