Abstract

The invention discloses a drainage basin water environment simulation and prediction method and device based on multi-model coupling, and relates to the technical field of environmental water conservancy and computational mathematics. Comprising the steps of obtaining input data of a to-be-predicted drainage basin; inputting the input data into the water environment prediction model; and based on the input data and the water environment prediction model, obtaining a water environment simulation prediction result of the to-be-predicted drainage basin, and completing dynamic simulation of the water environment of the to-be-predicted drainage basin from the drainage basin to the water body to the ecology. By forming a multi-dimensional nested land hydrology, hydrodynamic force and water environment coupling simulation framework, dynamic simulation of a water environment from a drainage basin to a water body to water ecology can be realized.

Description

technical field [0001] The invention relates to the technical field of environmental water conservancy and computational mathematics, in particular to a method and device for simulating and predicting water environment in a basin based on multi-model coupling. Background technique [0002] The hydrological model is the simulation and generalization of hydrological processes in nature. It is useful for the development and utilization of water resources, regional resource planning, water demand for ecological environment, flood control and disaster reduction, reservoir scheduling, point source and non-point source pollution evaluation, climate change and human activities. It plays an important supporting role in many aspects such as the impact on the watershed ecosystem. While pollutants generated by land units are discharged through point sources, rainfall runoff carries and exchanges soil water channel water into rivers and lakes. The quantitative description of the migrati...
