Abstract

The invention relates to a portable slope runoff water and sand collecting tank. The portable slope runoff water and sand collecting tank comprises a rain shielding plate, a beam flow plate, an anti-splash plate, a low roughness plate, a backwashing sealing plate, a lower baffle plate and a water outlet pipe. The rain shielding plate, the beam flow plate, the low roughness plate and the lower baffle plate form a closed triangular water and sand collecting tank, runoff of a runoff plot is quickly collected to the water outlet pipe, and the runoff volume and the sediment concentration are collected in real time by a sensor installed at the lower end of the water outlet pipe; and the portable slope runoff water and sand collecting tank is built at the downstream of the runoff plot, the anti-splash plate is flush with the lower edge of the runoff plot in spatial arrangement, the low roughness plate is in smooth transition with the ground of the runoff plot, and the gradient of the low roughness plate is slightly larger than that of the runoff plot. The portable slope runoff water and sand collecting tank is suitable for newly building and rebuilding a water and sand collecting device of a fixed runoff plot, and is also suitable for collecting runoff sediment in a field temporary runoff test, the accuracy of measured data of the slope runoff sediment can be improved, and the what you see is what you measure the runoff sediment in the slope runoff is achieved.

Description

technical field

[0001] The invention relates to a portable slope surface runoff water and sand collection tank, which belongs to the technical fields of water and soil conservation and hydrological experiments. Background technique

[0002] Rainfall runoff and sediment production is an important research content in the field of soil erosion and slope hydrology. Reliable measured data of runoff and sediment production is the key to understanding the mechanism of soil erosion and slope hydrology. The runoff plot is the main experimental facility for studying the mechanism of rainfall, runoff and sediment production. The runoff is collected by the water and sediment collection device arranged at the lower edge of the plot, and then real-time data such as runoff and sediment are collected, and the real-time data of runoff and sediment are used to represent the actual runoff plot. Flow and sand production information. This requires that the water collection and sediment collecti...
