The main purpose of the research was to create a comprehensive methodology to assess, predict and prevent the consequences of the negative impact of water-reservoirs on the environment, provide the safety of population and infrastructure; to find a way allowing jointly realize the interests of hydropower and coast protection. To achieve this goal, the following methods were used: full-scale experiment, field-expedition surveys on operating reservoirs, informational analysis, mathematical methods of least squares, ...

Construction of water-reservoirs across the rivers flowing into the sea often much complicates the coast protection problems. The reason is deficit of filling sediment on the coast-protecting beaches, which settle under the water. Consequently, two problems arise: efficiency of water-reservoir decreases and coastlines start to degrade what eventually ends with coast washing away and disaster. Main goal of is to develop the method of efficient solution of water-reservoir and coastal problems allowing maintaining th...

The current global climate variability is leading to significant changes in meteorological and oceanographic elements. A climatic background is formed, under the direct influence of which the reservoir affects the climate. The aim of the study is to create a method that can assess the combined impact of the main climate elements for a specific time interval and region. The following parameters of hydro- and meteorological elements are selected as the characteristics of such background: arithmetic mean and correspo...

Genesis, transport and accumulation of settled sediments of mountain rivers are such random processes in time and space, which are defined by the river flow rate (Q m3/s?c), height of the basin (IпїЅ), the inclination of the river and basin geology. Genesis and the volume of river sediment is the function of the climate and, in accordance with its cycles, it increases during the warming period and decreases as the temperature falls. The main natural factors for sediment formation are the glacier, erosion, landslid...
