Embodiment Construction

[0023] Combine below Figure 1 to Figure 4 , the present invention is further described:

[0024] An experimental equipment that can observe the migration of soil wetting fronts and collect soil flow in layers. The length, width and height of the soil tank designed for the experiment are 5m×2m×1.3m, which can simulate different subsurfaces during rainfall on a large scale The response relationship of surface, slope, rainfall intensity and previous soil moisture content to soil moisture migration.

[0025] 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.

[0026] Among them, (1) the waterproof device 6 at the bottom of the soil tank can prevent the soil moisture from leaking downwards...

Abstract

The invention relates to an experiment instrument capable of observing the migration condition of a soil wetting front and performing layered collection on interflow. The experiment instrument comprises a soil bin, wherein a waterproof device (6) is arranged at the bottom of the soil bin. The experiment instrument is characterized in that a protecting net for preventing soil from side leakage in a rainfall process is arranged on one side surface of the soil bin; multiple interflow layered collecting devices (7) are connected with one side, located in the soil bin, of the protecting net; multiple flow guide devices (4) are connected with one side, located outside the soil bin, of the protecting net; each flow guide device (4) and the corresponding interflow layered collecting device (7) are arranged correspondingly; the other side surfaces of the soil bin are assembled by steel plates (1) and tempered glass (2). The experiment instrument can be used for collecting overland runoff, interflow at different heights of the soil layer and groundwater runoff in the rainfall process and observing movement of soil moisture through the tempered glass (2).

Description

technical field [0001] The invention relates to the technical field of hydrology experiment research, in particular to an experimental equipment that can observe the migration of soil wetting fronts and collect soil flow in layers, which can be used to study the effects of different underlying surfaces, rain intensities, and slopes on soil moisture content. Response relationship for moisture transport. 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 patte...
