抄録

Experience in operation of water and drainage facilities in the northern and central Kazakhstan, Western Siberia, and others is explained. Regions where soils are predominantly light loam and sandy loam shows that the channel open reclamation and main channels undergo drift soil. As a result of this phenomenon channel capacity sharply decreases, and in some cases the channel is completely clogged. Annual cleaning of river beds channels by hand from the products of wind erosion or unproductive mechanisms, as is the case at present, leads to significant financial costs. The mathematical model of flow in a cavity of the channel wind flow at different flow rates, the wind and the varying degrees of entering the canal bed of sand-gravel material. This model can be used when assessing the degree of exposure drifts beds channels at the design stage and to predict the possible negative consequences.
