Abstract

The embodiment of the invention provides a water quality simulation method for river basins. The method comprises the following steps: dividing a river basin into a plurality of sub-basins, and acquiring data of each sub-basin in a specified time range; Taking the rainfall capacity and the potential evaporation capacity of each sub-basin as first input parameters, determining the effective rainfall capacity of each sub-basin through a nonlinear module of the hydrological model, taking the effective rainfall capacity of each sub-basin as second input parameters, and determining the non-point source runoff of each sub-basin through the linear module of the hydrological model; And taking the non-point source runoff volume, the temperature, the water quality detection value and the river hydrological data of each sub-basin as third input parameters, and obtaining a water quality simulation result of the river basin through a water quality analysis model. The embodiment of the invention further provides a water quality simulation system for the river basin. According to the embodiment of the invention, the influence of non-point source pollution on river water quality is considered in water quality simulation, and the accuracy of water quality prediction is improved.

Description

technical field [0001] The invention relates to the field of water quality simulation, in particular to a water quality simulation method and system for river basins. Background technique [0002] River water quality prediction is an important means to understand the trend of river water quality pollution, and an important means of river water quality pollution and its control and management. In order to clarify the ins and outs of the water quality pollution caused by river daily or accidents, predict the pollution situation that may be caused by the sewage discharge after the construction of the proposed factories and mines, calculate the capacity of the water environment, determine the discharge standards of water pollutants, and predict the water body after the implementation of water pollution prevention and control measures The possible improvement of water quality and the distribution of water quality require the establishment of a comprehensive and scientific method ...
