ResumoThe control of the Aley River flow-off by the releases from the Gilyovskoye water-storage reservoir is based on studying the effects of run-off redistribution on the downstream water regime of the river. The average water level at the Aley breakup at the cross section of Lokot village in the period of 1998-2007 at 128 cu m/s water flow made 290 cm above gauge datum. With increasing water flow up to 250 cu m/s, the levels do not exceed 400 cm. At the cross section of Rubtsovsk the average water flow at breakup is 64 cu m/s. At the water flow of 250 cu m/s the levels do not exceed 510 cm. When water is released from the Reservoir into the river bed at 50 cu m/s, the water levels, according to our observations, can reach 450 cm at Lokot and 460 cm at Rubtsovsk cross sections. If the flow makes 100 cu m/s, the levels at the same cross-sections with ice jams rise to 500-510 cm. Therefore, it is proposed to start spring flood period water release in late March with 20 cu m/s flow, and in April to increase of up to 50 cu m/s. By the end of the first ten-days of April it is proposed to increase the release flow to 200-250 cu m/s. The implementation of such procedure in the early days of the seasonal flood ensures ice breakup in the river, shattering, and passage with water levels eliminating the risk of flooding villages.
