For measuring the volume of flowing water and wash away the soil on the front wall of hydrolock installed stock-receiving equipment 17. Over hydrolocked mounted sprinkler 18 with a system of nozzles for dozirovannym way.

In accordance with the program of studies hydrolock give a certain longitudinal slope of the lifting frame 6 by the hydraulic cylinder 7 and is fixed by a screw mechanism 8. Then the hydraulic jacks 5 creates the transverse slope of the catchment. Modeling of rough terrain, forms both slopes (convex, concave, complex, direct) is achieved by the injection of gas or liquid in the cell filled with elastic elements 9. The required volume filled elastic element is fixed overlapping of the three-way valve 11. After the formation of the surface model of the catchment with a given shape of the slopes from soil 16 include a sprinkler.
