Description

technical field [0001] The invention belongs to the field of environmental water conservancy and computational mathematics, and in particular relates to a fast water quality simulation method and system based on a water environment coupling model. Background technique [0002] Under the situation of rapid social and economic development, strong human activities have accelerated the rate of change of the water environment, and also increased the complexity and uncertainty of the factors and directions of water environment change. A single water quality model has been unable to describe the impact of multiple pollution source variables on the water environment. The complex migration and transformation process cannot meet the high-precision requirements of water quality simulation. [0003] Realize high-level integration and coordinated development of the whole process of hydrology-hydrodynamics-water quality through multi-model coupling, and take into account the whole process...
