The questions of processing technology of dam channels using appropriate mechanisms are presented taking into account the requirements of modern engineering hydrology. Channel profiling with the best quality and performance can be carried out by means of mechanization at the expense of working tools, able to process not only longitudinal but also cross-sections of channels. According to calculations, there was established, that the best condition for moving soil on the channel slope in front of the passive knife, is an equable distribution along the slope. It was marked, that the strength of the soil pressure is most affected by the installation value of the trowel knife and the thickness of the loosened soil layer to be compacted. Recommendations on increasing the active working body stability of the dam profiler are given.

The article describes the technology of laying a film covering with a specially selected perforation of holes on the laid groove with fastening the edges of the covering along its entire length. Calculations of the irrigation rate are given, which must be strictly observed for economical water use when irrigating along furrows. The use of a perforated polyethylene film screen will provide the required moisture capacity throughout the season. Stabilization of the irrigation regime will ensure high yields while complying with the requirements of the law on environmental protection. The most effective agrotechnical conditions are proposed and recommendations for the growing season are given.
