Description
Technical Field
The invention relates to the technical field of water environment management, in particular to a watershed water environment business operation management platform.
Background
The watershed water environment management belongs to the key and difficult points of water environment management in China, and is also one of key factors for limiting long-term development of environment coordination and social economy in China. With the continuous development of computer technology and information technology, the informatization level of water environment management also makes great progress, and environment management departments in many regions also establish corresponding water environment management application platforms which are mostly oriented to common water environment management personnel. Therefore, the functions of the management platforms are usually limited to the functions of acquisition and entry of water environment monitoring data, water quality evaluation and water quality exceeding alarm, and the water quality condition known by managers is only limited to a few points of a monitoring section. However, many managers are concerned about water pollutants, and particularly, when a sudden water pollution accident occurs, how the pollutants are transported in a river or a lake (reservoir), when the pollutants can reach where, what the concentration is when a certain section is reached, is less. These problems can be solved by constructing a hydrodynamic water quality simulation model and performing numerical simulation on the pollutants. At present, the development of hydrodynamic water quality model simulation technology is relatively mature, and the technology is gradually developed from an initial zero-dimensional model to one-dimensional, two-dimensional and three-dimensional models. Particularly, the hydrodynamic water quality models such as MIKE11, delft3D, EFDC, WASP and the like are widely applied, so that a good technical support effect is provided for understanding the migration and diffusion processes of pollutants in a water body, and the models develop independent processing interfaces and display interfaces. However, users of these hydrodynamic water quality models are usually professional researchers, and have little application in the actual management of water environment, because these models require a profound background of professional knowledge and rich application experience, which are difficult for ordinary environmental managers to learn and use. In recent years, according to the requirement of water environment management, some systems or application platforms are embedded with hydrodynamic water quality models for simulating pollutants, so that the complexity of the model use is simplified and certain effects are achieved. However, the embedding method is usually implemented by professional hydrodynamic water quality model modelers and then integrated into a system or a platform, and the application of the model by environment managers can only be limited by the implemented model. If an environmental manager wants to custom simulate a body of water of interest, a professional modeler is required to re-model, which is time consuming, labor intensive, and not sustainable.
