Slope interflow simulation device and method for simulating interflow

Abstract

The invention provides a slope interflow simulation device and a method for simulating interflow. An existing interflow simulation device is difficult to really reflect the actual migration conditionof the interflow. In the invention, the above problem is solved. The device comprises a foundation groove and a slope control groove. The slope control groove is located above the foundation groove and sleeves the outer side of the foundation groove. A sealing component is arranged between the foundation groove and the slope control groove. The left end of the slope control groove is hinged to thetop of the left side surface plate of the foundation groove. A right arc surface plate matches with the right side surface plate of the foundation groove. A front sector plate and a rear sector platematch with the front surface plate and the rear surface plate of the foundation groove. The slope control groove can move up and down on the outer side of the foundation groove around a rotating shaft under the effect of an angle adjusting device so as to adjust a simulation slope. The two grooves adopt a transparent hard material and are provided with observation scale nets. A soil structure filled with the device is the same with an actual slope, and the structure with a thick soil layer in the upper portion of the slope and a thin soil layer in a lower portion is presented, which can trulyreflect the actual migration condition of the interflow.

Description

technical field [0001] The invention belongs to the technical field of soil moisture migration research, and in particular relates to a soil flow simulation device on a slope and a method for simulating soil flow. Background technique [0002] Soil middle flow is a kind of water flow movement in porous media. It is the water flow flowing laterally on the interface of the soil surface or layered soil layer. It is an important part of runoff. Because soil moisture is affected by the natural environment, the change is relatively However, soil midflow plays a very important role in watershed runoff regulation, water conservation, sediment migration, nutrient loss, and calculation of watershed hydrological cycle. Therefore, the study of soil midflow is particularly critical. [0003] As for the monitoring method of soil inflow, it was firstly used in the field of hydrology and hydrogeology, mainly by speculating and calculating the change of runoff in different rainfall processes...

AI Technical Summary

Problems solved by technology

[0004] However, there are still the following problems in the existing simulation of soil flow: 1) The overall thickness of the soil layer of the simulator is basically the same, and the bottom of the simulator will affect the actual movement of the soil flow in the upper part of the slope; The soil tank is inclined, and the upper and lower baffles of the soil tank are inclined accordingly, and the entire soil structure will be subjected to the tilting force, which will also affect the migration of the soil midflow on the slope; 3) lack of soil moisture during the formation of the soil midflow Dynamic monitoring of the migration process of soil and soil

The above problems will have a greater impact on the authenticity of simulated soil flow by those skilled in the art, and the reference of the research results is poor
