Abstract

The invention discloses a dual-varying-slope erosion groove and interflow determining instrument and a determining method thereof. A model fixing support formed by welding a lower soil erosion groove, an upper soil erosion groove and a steel frame is arranged, and the upper and lower bottom ends of the model fixing support are each connected with a lifting device. The upper soil erosion groove and the lower soil erosion groove are connected through a plastic transition belt. The soil erosion groove is divided into a left part and a right part through a soil erosion groove partition plate, and the lower soil erosion groove is connected with an interflow collector and a surface flow collector. The invention further relates to the determining method adopting the dual-varying-slope erosion groove and interflow determining instrument in the soil water erosion process; by adopting the instrument, slope surface micro-topographies of different concave-convex forms can be constructed; by determining interflow, surface flow, sediment, slope surface erosion morphology, the number and sizes of rills and other important parameters, quantitative analysis can be performed on the rules of occurrence and development of soil water erosion in the whole precipitation process, and the application range is wide.

Description

technical field [0001] The invention relates to soil erosion monitoring, more specifically to a measuring instrument and a measuring method for a double variable slope erosion tank and soil flow. Background technique [0002] Slope soil erosion process and hydrological characteristics are one of the essential contents in the study of soil and water conservation. However, the relative importance of different runoff components in the slope water erosion process has not attracted enough attention. The traditional slope soil The measurement of erosion process mostly focuses on surface erosion and rill erosion, and mainly focuses on the hydrological process of surface runoff, ignoring the influence of soil inflow on the erosion process. Soil midflow can affect soil shear strength by affecting soil pore water pressure. The hydraulic gradient potential difference in the process of seepage measurement can change the resistance of soil particles to break away from the soil matrix, an...
