FIELD: construction.
SUBSTANCE: method involves installation of waterproof cross fencing in winter in the pre-selected place on the bed of mountain river. Dam, forming the upper pool in front of it, is constructed above the fencing down-stream, from which short-term water discharges are executed at negative air temperatures. Each of the discharges is interleaved by pause in time until the freeze of the discharged water and water on the surface of the upper pool, forming two ice-catchment basins, lying on the ground of the river bed. One of the basins is located above the fence, and the other - above the dam. Cycle of basin formation is repeated for several years until the thickness of the ice in basins reaches the value greater than 80 m. Ice-catchment basins in the southern latitudes of the Earth are formed at the altitude greater than 2500 m above the sea level.
EFFECT: irrigation of lands on piedmont territories throughout the spring-summer period.
