Abstract

The invention relates to the technical field of geographic data processing and modeling, hydrodynamic simulation and water conservancy forecasting, and discloses a watershed water level and waterlogging forecasting method based on weather forecasting and hydrodynamic simulation. The method comprises the following specific implementation steps: S1, determining a research area according to researchrequirements, and planning a watershed boundary of a researched water area; and S2, determining a research riverway, delimiting riverway boundaries according to requirements, and correcting the riverway boundaries. The method comprises a whole river channel and urban area modeling process and simulation steps as well as a simulation adjustment and correction method. The method is based on comprehensive application of a computational fluid mechanics method. The steps combined with the actual situation are described in detail; the method further comprises a geographic information technology, a weather forecast technology, an automation technology and the like, the problem that urban inland inundation and river flow velocity and flow distribution need to be actually displayed at present is actually solved, the capacity and precision of water conservancy simulation forecast are improved, and technical combination with water conservancy related professions is developed.

Description

technical field [0001] The invention relates to the technical field of geographic data processing and modeling, hydrodynamic simulation and water conservancy forecast, in particular to a water level and waterlogging forecasting method based on meteorological forecast and hydrodynamic simulation. Background technique [0002] In the past, there were many problems in the process of hydrological forecasting, due to the high cost of finite element modeling and the excessive calculation time of high-precision modeling. With the rapid development of Internet of Things technology and the rapid popularization of high-performance computing, the problem of calculation volume has been greatly alleviated. In the context of severe water conditions and urgent demand for machines in the flood season of 2020, how can the real river course be carried out in a short period of time based on accuracy? The simulation and forecast of water regime has become the top priority of water conservancy m...
