Embodiment Construction

[0018] The terminology used in describing various examples in this disclosure is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, there may be one or more elements. In addition, the term "and / or" used in the present disclosure covers any one and all possible combinations of the listed items.

[0019] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0020] The present invention firstly discloses a method for predicting river water flow generated by precipitation runoff in a region. The above-mentioned region refers to a specific two-dimensional region in geography, and the region can be in various shapes such as circle, square, trapezoid, etc. two-dimensional area. The above-mentioned area includes the land part and the river part, and th...

Abstract

The invention relates to a device and method for predicting river water flow generated by rainfall runoff in a region. The method comprises the following steps: segmenting the region into a plurality of grids; obtaining rainfall data, a vegetation interception water amount and a soil infiltration water amount in the grids; determining the rainfall allowance of each grid according to the rainfall data, the vegetation interception water amount and the soil infiltration water amount; determining surface runoff in the region according to the rainfall allowance of the plurality of grids in the region; and determining the river water flow according to the surface runoff and the river characteristics in the region. According to the method disclosed by the invention, the absorption of vegetation and soil in the region on precipitation and the surface runoff from each grid to the adjacent grid are accurately considered, and finally, the water flow of the river channel is calculated. According to the method disclosed by the invention, each geographical factor influencing the river water flow in the to-be-predicted region is comprehensively considered, so that the calculated river water flow is more accurate.

Description

technical field [0001] The invention relates to the field of hydrological models, in particular to a method, device, electronic equipment, non-transient computer-readable storage medium and computer program product for predicting river channel water flow generated by precipitation runoff in a region. Background technique [0002] River and coastal flood prediction is a major research topic in current world water resources management. Drainage and river flood protection are major issues to be considered comprehensively in important decisions concerning the construction of reservoirs and water conservancy facilities, etc. At present, many researchers are trying to find better ways to analyze and predict this natural phenomenon, so as to effectively assess the risk of river flood events, and to take appropriate and effective measures to prevent or reduce the damage and adverse effects caused by river floods. [0003] However, the methods currently used to assess or predict riv...
