The utilization of groundwaters for the agriculture and water supply in arid climate areas is important for water management purposes. The evaluation of the water reserve formation, including groundwater, is one of principal element of this activity. The territory between Prut and Dniester rivers of the Republic of Moldova is situated at the Moldavian artesian basin, which is part of the Black Sea artesian basin. According to its hydrodynamic properties, the Moldavian artesian basin can be considered as a separate basin, the borders of which are the Dniester, Prut rivers and the Black Sea in the south. This basin is connected to the VolynPodolsk artesian basin from Ukraine at the north by a narrow strip in the northwest and their interaction is limited. The principal aquifers are transboundary in this region between Romania, Ukraine and Republic of Moldova. The aim of this work is a creation of conceptual model for groundwater recharge evaluation. There are seven main stratigraphic rock groups, which form principal aquifer systems. The conceptual model of the groundwater system includes the seven aquifers. The water-bearing rocks are mainly limestone, sand, sandy loam, and sandstone. Between the aquifers and the complexes, there are no thick and regionally sustained lowpermeability strata. The basin structure is a single hydrodynamic system, consisting of several aquifers and complexes interacting through weakly permeable sediments and hydraulically connected with surface waters. Regional waterproof layers are clays of middle Sarmatian, clays of Podolsky Formation of lower Baden. The local aquitards can be quaternary, alluvial clayey rocks. The principal information about studied transboundary aquifers can be obtained at site http://geologie.gov.md/ The aquifer recharge takes place directly on the territory of the basin due to the infiltration of atmospheric precipitation and river runoff. The groundwater discharge is river network, Black Sea, and water supply. The implementation of stable isotope technology for the evaluation of the water cycle (precipitation, river water, groundwater interaction) and groundwater reserve formation is proposed for the implementation in this work. |
