Peculiarities of hydrodynamics of water reservoirs characterized by the vertical density inhomognneity of water masses under active technogenesis conditions

The results of numerical modeling and field studies the stability technical water supply large industrial enterprises are presented. Water consumption is one most important indicators reliability operation such enterprises. This problem especially acute for located in zones active technogenesis, where dominant factor formation pollution bodies undeclared dispersed, so-called diffuse sources pollution. reservoirs created this territory purposes have a number features that must be taken into account when designing them. To solve problem, relatively small special often created. When creating them, it priori assumed masses formed them will uniform area depth. At same time, order to prevent possible accumulation pollutants lower near-bottom horizons, as rule, they flushed. However, experience operating development zone Verkhnekamskoe potash magnesium salt deposit (VKMKMS) (Ural, Russia) has shown these reservoirs, due intense pollution, significant vertical heterogeneity formed, which fundamentally changes hydrodynamics bodies. On basis set studies, including observations computational experiments, plays key role ensuring sustainability supply.
