FACTORS FORMING OF UNDERGROUND WATERS REGIME ON THE ZMIINYI ISLAND

Abstract

Study of underground water regime is one of components in the general hydrogeological researches. Aim of the work has been to define the main regime-forming factors of underground water in the Zmiinyi Island. Study object is underground water; subject of the work is the main features of the underground waters regime and the factors of its formation. Methodology. It was comparing hydrogeological and meteorological characteristics (sea level, atmospheric pressure, atmospheric precipitation) with dynamic (level, pressure) and physicochemical (temperature, salinity) parameters of underground water for ascertainment of regularity formation of underground water regime. Date processing has being done with mathematical statistics methods. General characteristic of hydrogeological conditions on the Zmiinyi Island has been given. It has been analyzed temporal variability hydrodynamic and physicochemical elements of underground water under natural conditions and in conditions of anthropogenic impact on the results of underground water monitoring system introduction, as well as on the basis of longterm monitoring observations meteorological and hydrological parameters on the island. Results. It has been shown that the underground water regime is being formed on the Zmiinyi Island under natural conditions influenced by exogenous (meteorological, hydrological) and exogeodynamic (atmospheric pressure) groups factors, while water abstraction causes disturbed regime.
