Slope water balance field observation device and observation method applying same

Abstract

The invention relates to the technical field of soil erosion and forest hydrology, and discloses a slope water balance field observation device. The slope water balance field observation device comprises an isolation side wall, a header tank, a retaining wall and a collecting device, wherein the isolation side wall is arranged on the bed rock face of a slope, the header tank is arranged corresponding to the isolation side wall, a surface layer flow guide pipe and in-soil flow guide pipes are arranged in the retaining wall, the surface layer flow guide pipe is arranged corresponding to the header tank, and the surface layer flow guide pipe and the in-soil flow guide pipes are communicated with the collecting device. As the surface layer flow guide pipe and the in-soil flow guide pipes are arranged in the retaining wall, the slope water balance field observation device can observe interflow of soil in layers and verify a water balance equation well to comprehensively observe the slope water process; the slope water balance field observation device has the advantages of being simple in structure, facilitating observation and the like.

Description

technical field [0001] The invention relates to the technical fields of soil erosion and forest hydrology, in particular to a slope surface water balance field observation device capable of observing the slope water balance process and an observation method using the device. Background technique [0002] Water balance is the basis for the analysis and research of hydrological phenomena and hydrological processes, as well as the basis for the calculation and evaluation of the quantity and quality of water resources. Slope water balance field is a common method to study the water balance process and soil erosion process of slope under natural rainfall conditions. The traditional research method is to establish a runoff test plot. The design principle is to simulate the natural slope, and collect the runoff and sediment on the slope through the collection tank, so as to study the hydrological process and soil erosion process of the slope under natural rainfall conditions. The ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the traditional slope runoff plots cannot observe the soil infiltration process and soil flow process, and in order for the runoff to not overflow in the collection system, it is often necessary to build a huge one-stage or multi-stage diversion system. The diversion facilities not only increase the project cost, but also the work of drainage and sand removal is labor-intensive and time-consuming
