Transformation of the Ob river channel downstream of the Novosibirsk hydroelectric station

Conclusions

Investigations of processes of transformation of the Ob channel in the lower pool of the Novosibirsk hydrostation convincingly show the need for timely consideration of the consequences caused by man's interference in the life of the river. The preparation of a scientifically founded forecast of channel transforamtion when designing hydrostations should include an assessment of the effect on the fluviomorphological process of quarry excavations, training works, and construction of intake and outlet works. Insufficient consideration of these factors and the lack of due supervision of works affecting the course of the fluviomorphological process under conditions of a river with a regulated flow can be the cause of irreversible channel transformations and changes in the hydraulic regime which can effect substantial complications for various branches of the economy.
