South tidal river network area water flow and water quality coupling simulation system

Abstract

The invention provides a south tidal river network area water flow and water quality coupling simulation system, which comprises three modules: a data input module, a model base and a data output module, wherein the model base comprises a water flow mathematical model and a water quality mathematical model. The water flow mathematical model can be used as a separate module, carries out analysis calculation on input terrain, water intake engineering data, hydrologic data and the like, adopts a flexible user interface so as to conveniently carry out secondary processing, required by a user, on the data, and provides a basic data support for the water quality mathematical model. The water quality mathematical model is organically combined with the water flow mathematical model, so that simulation on river water quantity of a large-range river network area on the basis of the water flow mathematical model is implemented; moreover, a gate dam, water intake and drainage and the like can be flexibly set, so that practicality and applicability of the system are reinforced.

Description

technical field [0001] The invention relates to the technical field of water environment mathematical models, and more specifically, to a water flow and water quality coupling simulation system in a southern tidal river network area. Background technique [0002] With the rapid development of urbanization and the rapid growth of urban population, the demand for urban water supply continues to increase, coupled with the massive discharge of industrial wastewater and domestic sewage, making the already prominent contradiction between supply and demand of water resources and water pollution problems more severe. How to draw water scientifically and rationally and discharge pollutants has become an urgent problem to be solved for the sustainable utilization and development of water resources and the protection of water environment. [0003] The mathematical model of the water environment is to describe the hydrodynamic problems and the migration and transformation of pollutants ...

AI Technical Summary

Problems solved by technology

The internal structure of the tidal river network is intricate, and the water flow and tide reciprocate, which makes the equations discrete and very difficult to solve. This is a major difficulty for people to study river network problems for many years, and therefore many mature water environment mathematical models are often no longer applicable.

Moreover, the existing domestic related technologies mainly focus on theoretical research, lack of necessary investment in the development of models and software, and have few achievements that can be used in actual operation.

In addition, in the design process of the model, factors such as complex river topography, initial boundary conditions, and tidal fluctuations are ignored, resulting in poor stability and drawability of the model and overly complicated use; in addition, in a small number of operating systems, the main The simulation of water flow and water quality for a single river or a small-scale watershed is relatively common, but it is not applicable or has low accuracy for the simulation of water flow and water quality in a large-scale complex network of river areas; , such as the construction of sluices, dams, bridges, water intake projects, etc., which affect the hydrodynamic process of the river, it is difficult to meet the current new situation and the frequent occurrence of new problems in the development and utilization of water resources and the protection of the water environment
