Description

Technical Field

[0001] The utility model belongs to the field of soil and water conservation and desertification prevention and control, and particularly relates to a soil erosion ditch section measuring device. Background Art

[0002] Gullies are linear, trough-shaped depressions. They primarily develop on loose sedimentary layers in semi-arid climate zones. In gently sloping areas with sparse vegetation, gullies can develop rapidly, severely fragmenting the terrain, encroaching on arable land, damaging roads, and causing massive soil and water loss. In the process of managing gullies, it is necessary to measure their gradient, depth, width, and catchment area, and to draw gully planes and cross-sectional diagrams. The irregularity of naturally formed gullies increases the difficulty of measuring catchment area. Therefore, in order to improve the accuracy of measuring gully catchment area and drawing gully planes, it is necessary to use soil gully cross-sectional measurement devices that are convenient for field measurement to improve the scientific nature of soil and water conservation, gully restoration, and construction volume calculations.
