Method and device for measuring silt deposition amount of silt dam, computer and storage medium

Abstract

The invention provides a method for measuring the silt deposition amount of a silt dam, and the method comprises the steps: constructing an initial empty channel model based on a plurality of solid empty channels, simulating the construction of the silt dam in the initial empty channel model, and obtaining a plurality of target empty channel models; performing sediment deposition process simulation of different sediment deposition depths on the plurality of target empty channel models, determining multiple groups of sediment deposition areas and sediment deposition volumes, and obtaining a deposition sample set; fitting the deposition sample set to obtain a target relational expression of sediment deposition area-sediment deposition volume; obtaining the sediment deposition area of the to-be-measured silt dam; and according to the silt deposition area of the to-be-measured silt dam and the target relational expression, the silt deposition volume of the to-be-measured silt dam is obtained, and the silt deposition amount of the to-be-measured silt dam is obtained according to the silt deposition volume. The invention further provides a measuring device for the silt deposition amount of the silt dam, a computer and a storage medium. The defects of efficiency, cost, precision and the like of a traditional method are overcome, and the applicability is wider.

Description

technical field [0001] The invention relates to the technical field of water and soil monitoring, in particular to a method, a device, a computer and a storage medium for measuring the sedimentation volume of a check dam. Background technique [0002] Check dams refer to dam structures built for the purpose of retaining mud and silt in all levels of ditches in soil erosion areas. They play an important role in maintaining soil erosion, reducing sediment in the Yellow River, and developing agricultural production. Obtaining information on the amount of sediment deposited by check dams is of great significance for evaluating the effectiveness of check dams, studying soil erosion, and predicting changes in water and sediment in the Yellow River. [0003] At present, the methods for estimating the amount of sedimentation in check dams at home and abroad mainly include the following: (1) monitoring data derivation method, based on the construction design data of check dams and fi...
