FIELD: agriculture, in particular, gully erosion preventing equipment, which may be used as hydraulic structure for suppressing energy of falling water.
SUBSTANCE: apparatus has overhanging overfall formed as converging chute with branch pipe formed as crank and fixed at rear converged end of chute. Round opening of branch pipe is directed downward. Energy suppressor positioned under round opening in water splitting pit is formed as floating sphere connected with anchor post fixed in water splitting pit bottom by means of rope and adapted for self-centering under the action of stream flow. Guiding posts-tree cuttings are planted around sphere at distance making 0.5 of its diameter. Diameter of sphere exceeds that of outlet opening of branch pipe by more than three times. Sphere and overhanging overfall are of black color. Sphere may have conical lower part.
EFFECT: increased efficiency in controlling of gully erosion and wider operating capabilities.
