FIELD: construction. ^ SUBSTANCE: invention relates to melioration, particularly to operation of drainage-irrigation systems. Method of struggle with spring flood includes opening cavity in snow cover of meliorative channel along its axis by means of snow compaction and movement, drainage of spring flood along channel. Cavity in snow cover is opened from surface, compacting snow by means of its simultaneous movement in directions towards bottom and channel slopes. Cavity that geometrically comply with channel cross section is formed. Temporary protective coating is formed in process of snow compaction at the bottom and slopes of channel. ^ EFFECT: invention makes it possible to improve reliability of the system due to preservation of throughput section formed in snow fill of meliorative channel, and to protect channel bottom and walls against excessive washing. ^ 2 dwg |
