Embodiment

[0058] Table 1 shows the relationship between the silted elevation and the silted storage capacity of check dams with different dam heights:

[0059] Table 1 The function relationship between the silted elevation and the silted storage capacity of check dams with different dam heights

[0060]

[0061]

[0062] According to table 1 Figure 1(a) ~ Figure 1(g), obtain the relationship curve between the silted elevation and the silted storage capacity of different dam heights. For the 35 check dam samples modeled in Figure 1, establish the functional relationship of the above formula 1 respectively, calculate a and b, and establish a , b relationship scatter plot, such as figure 2 shown.

[0063] In this embodiment, 5 check dams located in Shanxi Province are selected, the total dam height H and total storage capacity V of each check dam are known, and the silted elevation is determined by actual measurement and calculation, see Table 2 for details. The total dam height ...

Abstract

The invention discloses a quick calculation method for deposited reservoir capacity of an above-medium-sized warp land dam. The method is implemented specifically according to the following steps of 1, collecting deign files of multiple above-medium-sized warp land dams in a research region, and fitting a deposited elevation-deposited reservoir capacity relationship; 2, for the sample relationshipobtained in the step 1, establishing a function relationship; and 3, for the function relationship obtained in the step 2, fitting a mathematic relationship to obtain the deposited reservoir capacity. The problems of difficult calculation of the deposited reservoir capacity due to missing of the design files of the warp land dams, high estimation workload and low precision in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of geography and soil and water conservation monitoring, and in particular relates to a method for quickly calculating the accumulated storage capacity of a check dam above a medium size. Background technique [0002] The check dam is one of the main soil and water conservation engineering measures in the Loess Plateau, and it has played an important role in reducing the flood, cement and sediment problems in the Yellow River and ensuring the safety of the Yellow River. Determining the sediment retention capacity of a check dam is of great significance for evaluating the sediment retention benefit and retention potential of the check dam, analyzing the sediment reduction contribution rate of each underlying surface factor, and predicting the future sediment flow of the Yellow River. [0003] The current methods for estimating silted storage capacity at home and abroad mainly include the following: (1) the da...
