Description

one

The invention relates to agriculture, and in particular to the study of erosion processes that occur on the surface and in the first soil

The purpose of the invention is to increase the reliability of research in modeling soil erosion processes, which are dependent on the flow of snowmelt snow nods.

Fig, 1 shows the installation, side view; in fig. 2 is a section A-A in FIG. one.

The installation for modeling erosion processes of the soil arising from the runoff of snow melt water is fixed on frame 1 and consists of a heat-insulating mobile unit 2 with iridescence 3 for changing the angle of inclination and lysimeter vessels in the rolls of hydraulic trays A with soil located in the zone of action beam generator

6 heat. Along the length of the hydraulic tracks 4, there are installed transverse movable walls-limiters 7. At the bottom of the heat insulating unit 2, a perforated plate 8 and thermal elements 9 are mounted with an automatic regulator 10 for changing the intensity of heat energy transfer by the soil monolith. The heat insulating unit 2 on the side of the ice trays A is equipped with removable cassettes 11 for loading snow and a freezing chamber 12 with the possibility of alternating disconnection and separation from the block 2. Sensors 13 for soil temperature and humidity are installed at different depths from the surface of the hydraulic trays 4. In the bottom of the block 2 mounted drainage 14 subsurface flow, and in the end part - drainage 15 surface runoff.

The installation works as follows.

An agraphone is created on the surface of the soil in each hydrotour 4, and along the length of each hydrotray 4 a transverse moving wall limiters corresponding to the simulated slope are installed at a given length. Using tool 3 to change the angle of inclination of the Z block with hydro 10

trays 4 give the slope of the surface corresponding to the studied slope. Then the soil moisture in hydrolowers 4 is adjusted to the specified parameters. On the surface of block 2, a freezer compartment 12 is hermetically sealed, which brings the temperature of the soil to a predetermined freezing depth. The soil freezing process is monitored by sensors 13.

After that, the freezer compartment 12 is turned off and disconnected from unit 2. Removable cassettes 11 are placed on the surface of the hydraulic tracks 4 with the soil, into which individual portions of snow are loaded by weight. Then the beam heat generator 5 and the thermal elements 9 are turned on. After the snow has been compacted, the cassettes 11 are removed.
