River channel water volume prediction method

Abstract

The invention relates to the technical field of hydraulic engineering, in particular to a river channel water volume prediction method which is mainly used for predicting the river channel water volume. The method is used for predicting the water volume based on a meteorological model, a hydrological model and a hydrodynamic model, and comprises the following steps of S1, constructing the meteorological model to calculate meteorological data of a riverchannel research area, S2, constructing a hydrological model, and calculating flow data of the riverchannel boundary through the meteorological data, and S3, constructing a hydrodynamic model, and calculating river channel water volume data through the flow data of the river channel boundary. According to the method, the flow data of the river channel boundary are determined through coupling of the meteorological model and the hydrological model, the hydrological model provides the flow data of the river channel boundary for the hydrodynamic model through coupling of the hydrological model and the hydrodynamic model, and then future flow data on the model boundary are provided for predicting the future river channel inflow. And the hydrodynamic model can predict the future water volume.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a method for predicting the water volume of a river, which is mainly used for predicting the water volume of a river. Background technique [0002] The accuracy of the forecast of water flow in the upper reaches of the river can greatly improve the scientific nature of small hydropower generation scheduling, thereby improving the utilization rate of water energy, improving power generation efficiency, and increasing economic benefits for hydropower station owners; at the same time, it is conducive to scientific planning of ecological flow and the enthusiasm for ecological water release. Reducing the impact of small hydropower on the ecology will bring important social significance to the improvement of the downstream ecological environment. At present, the most widely used method is to use the hydrodynamic model to simulate the historical situation of the river wate...

Problems solved by technology

The data collection process in this patent is relatively complicated, and the complexity of the ecological environment in different regions is different, which has caused certain difficulties in the collection of corresponding regional environmental data

Moreover, due to the different ecological environments, the fusion of data in each region also needs to be carried out in a targeted manner, resulting in a large amount of pre-simulation workload.
