Water management and technical scheme to ensure environmental releases from Bartogai reservoirs

Abstract

In the article the results of research of nature releases from Bartogay reservoirs and the water-technical scheme of providing. Studies have shown that the daily regulation waves of releases play a major role in the downstream channel regime in the first years of operation of the hydroscheme, then, as the general erosion of the channel develops, their influence is somewhat weaker. Since the flow velocities in the frontal part of the pop-up waves are very high (they may be 2–3 times greater than the velocities of the undisturbed flow), a wave of sediment moves along with the frontal part of the pop-up wave. In a fixed station, this is recorded as a sharp peak in sediment flow. Despite the relative briefness of such peaks, they lead to an overall increase in the mobility of bottom forms and cause intense drift of shipping gaps. High current velocities in the propagation of popup waves intensify coastal erosion.
