CHANNEL CLEANING METHOD Russian patent published in 2006 - IPC E02B3/02 E02B15/00 

FIELD: hydraulic equipment, particularly to clean channels of silt.

SUBSTANCE: method involves cutting down unnecessary trees, bushes and weed vegetation along irrigation channel berms and slopes; removing the cut down trees, bushes and weed vegetation; treating stubs of the trees and bushes and stubble remaining after weed vegetation removing. The stubs and stubble treatment is performed after hydraulic cut down trees, bushes and weed vegetation washing down to channel bottom. The stubs and stubble are trimmed for maximal possible height, the grinded fraction, silt, mineral and other waste is washed down to channel bottom. Water level in the channel is raised for height equal to 1/4-1/3 of channel depth and then decreased. Coarse fractions are removed from blocking grid surface. Fine fractions are trapped by meshed networks.

EFFECT: reduced power and labor inputs for channel cleaning and increased channel throughput.
