FIELD: hydraulic equipment, particularly means for stream regulation, for instance breaking up subaqueous rock, cleaning the beds of waterways, directing the water flow.
SUBSTANCE: method involves cutting saplings, bushes and weed vegetation in area along irrigation channel berms and slopes; removing the cut saplings, bushes and weed vegetation and treating stumps and stubble; washing off the cut saplings, bushes and weed vegetation with water to bed bottom before stumps and stubble treatment; milling stumps and stubble so that final stumps and stubble have heights of 4-6 cm; washing off grinded fraction, silt, mineral and other rubbish with water to bed bottom; elevating water level in channel to height equal to 1/4-1/3 of channel depth; lowering water level in channel; removing coarse fractions from protective grid surfaces; gathering fine fractions by cellular meshes.
EFFECT: increased channel throughput and pumping installation capacities.
