Embodiment Construction

[0036] Combine below Figure 1 to Figure 8 , the present invention is further described:

[0037] A soil tank that can 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 different underlying pads in the rainfall process on a large scale The response relationship of surface, slope, rainfall intensity and previous soil moisture content to soil moisture migration.

[0038]As shown in the accompanying drawings, the experimental equipment that can observe the migration of the soil wetting front and collect the soil flow in layers mainly includes: the bottom waterproof device 6, the tempered glass 2 on the side, the fine gauze net 9, the iron net 10, the soil flow Layer collection device 7 and flow guide device 4.

[0039] Among them, (1) the waterproof device 6 at the bottom of the soil tank can prevent the soil moisture from leaking downwa...

Abstract

The invention relates to devices for collecting interflow. The devices comprise soil bins loaded with soil, the multiple devices for collecting the interflow are inserted in the soil to collect soil moisture at different points, and the moisture of soil, which cannot be seen by naked eyes, inside the soil bins is subjected to data collecting and analyzing. The devices for collecting the interflowcan be buried in the soil, can collect the soil at different depths and can analyze the water content of the soil, and thus the transfer situation of the soil wetting front and the response relationship of the soil wetting front to rainfall are reflected more objectively.

Description

technical field [0001] The invention relates to the technical field of hydrology experiment research, in particular to a device that can observe the movement of soil wetting fronts and collect soil flow in layers, which can be used to study the effects of soil moisture content on different underlying surfaces, rain intensities, and slope gradients. Responses to transport conditions. 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. Theref...
