Basyuk T. Estimation of hydrological and gidroekologichnikh terms of development and reconstruction of the small hydroelectric power stations (on the example of the river Sonth Bug).

The paper analyzes the small hydro, highlights the socio- economic aspects of rehabilitation of small hydropower plants, studied the effects their impact on the environment, considers the development of the hydropower potential of the Southern Bug River within the Vinnytsia region. We consider the natural conditions South Bug River Basin reservoirs in zones of influence. Shows the hydrographic features of the study area. The basic features of the hydrological regime observations. The estimation of the impact of water management on water resources for quantitative and qualitative indicators, namely: analysis using reservoir water management, environmental assessment carried out water quality investigated the hygienic condition odoshovysch. The estimation of the projected impact of reservoirs in case of changes tiered regime, including: formation of water regime of the South Bug, realignment of the coast, forming the groundwater level, quality of surface waters. The measures to reduce environmental risks due to harmful effects of water at higher water levels in reservoirs. Done ecological and economic evaluation of natural resources by changing tiered regime of reservoirs.
