Problems solved by technology

[0005] Although the existing device that directly observes the movement of soil moisture through a glass window makes the observation more intuitive, the movement of moisture inside the soil is more complicated. The glass window only reflects part of the facts, and cannot accurately understand the inside of the soil layer that is invisible to the naked eye. Demonstration of the soil wetting front

Embodiment Construction

[0046] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] combine Figure 1 to Figure 4 As shown, a soil tank can be used to observe the migration of the soil wetting front and collect the soil flow in layers. The length, width and height of the soil tank in the experimental design are 5m×2m×1.3m, which can simulate the rainfall process on a large scale. Response relationship of different underlying surface, slope, rainfall intensity and previous soil moisture content to soil moisture migration.

[0048] The experimental equipment that can observe the migration of the soil wetting front and collect the soil midflow in layers mainly includes: the waterproof device 6 at the bottom, the tempered glass 2 on the side, the fine gauze 9, the iron net 10, the layered collection device 7 for the soil midflow, and the guide. flow device4.

[0049] Among them, (1) the waterproof device 6 at the bottom ...

Abstract

The invention discloses a control method of a device for collecting the subsurface flow through vertical extrusion. The device for collecting the subsurface flow through vertical extrusion can be buried in the soil and can collect and analyze the moisture content of soil at different depths, thereby being capable of more objectively reflecting the movement of the soil wetting front and the response relation thereof to rainfall.

Description

technical field [0001] The invention relates to the technical field of hydrology experiment research, in particular to a control method of a device for collecting soil midflow through vertical extrusion. Background technique [0002] Under the dual influence of climate change and human activities, the evolution of water cycle in the basin is undergoing profound changes. Climate change affects the hydrological cycle by changing precipitation, temperature, sunshine, wind, relative humidity, etc., and then changes the temporal and spatial distribution of precipitation, runoff, evaporation, soil moisture and other hydrological elements. Human activities affect the hydrological cycle process by changing the underlying surface of the basin and the spatio-temporal distribution pattern of water. Therefore, the response relationship between soil moisture change and runoff during the rainfall process, or the response relationship between different slopes, rainfall intensities, and un...
