Problems solved by technology

When measuring the soil erosion rate in the existing wave tank experiment, the soil vertical erosion measurement under the action of waves and currents usually uses methods such as measuring the critical flow velocity near the bed and the erosion depth. beach, which cannot be applied to the front of salt marshes (swamps) with a slope close to vertical, that is, there is no measurement method for the lateral erosion rate of the vertical surface of the soil caused by waves in the prior art

Embodiment Construction

[0025] In order to make the objects, technical solutions, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] See figure 1 , figure 1 The flow chart of examples of the soil transverse erosion quality measurement method of the present invention includes:

[0027] S101, collect soil samples by sampling tubes.

[0028] It should be noted that the soil sample is taken from the slope close to the vertical salt (swamp) front edge. In order to keep the soil samples in the erosion process, the present invention employs a PVC tube as a sampling tube, low price, easy to obtain, quality, convenient field sampling; at the same time, considering the sample amount of the soil sample, the sampling tube The diameter is 15 cm, the columnar soil sample that can be collected is greater than the preset depth, the preset depth is preferably 15 cm, but is not limited thereto.

Abstract

The invention discloses a method for measuring soil lateral erosion quality, comprising: collecting soil samples through a sampling tube; There is a side opening connected with the bottom opening; a soil lateral erosion quality measurement device is arranged, and the sample tube is placed in the soil lateral erosion quality measurement device, and a pressure sensor is arranged under the sample tube; the sample tube is controlled by the soil lateral erosion quality measurement device The soil samples in the test are subjected to wave tests, and the continuous pressure information during the wave test is collected in real time through the pressure sensor; the soil lateral erosion rate of the soil samples is calculated according to the continuous pressure information. By adopting the invention, the accurate quantification of the soil lateral erosion rate under the action of waves in coastal wetlands and reservoir areas can be realized.

Description

Technical field [0001] The present invention relates to the field of ecological engineering, and in particular, to a method for measuring soil transverse erosion quality. Background technique [0002] Under the action of strong hydrophilic factors such as waves, the leading edge of the coastal wetland and the reservoir lakeside belt forms a step-shaped steep slave. As the dynamic factors continue to function or enhance, the steep kangee sediments will have an enrichment or even collapse, causing the overall enrichment of vegetation, threatening the safety of the coastal and inland waters. Sediment erosion means the reduction in vegetation area and the loss of ecological service functions. The mature planting of coastal wetland has an important ecological service function such as surrell increasing and maintenance of biodiversity. The stability of the reservoir belt is important for maintaining the safety of the reservoir. Therefore, the stability of the deposit under wavy wash, a...
