The Dobrudzha Coal Deposit is characterized by complex geological, tectonic and hydrogeological conditions. The formed aquifers and complexes, on the one hand, hinder the possible exploitation of the coal deposit, on the other hand they are important for drinking water supply in the area. The aim of the present study is to develop a 3D hydrodynamic model in the area of the deposit to elucidate the dynamics of the flow processes, the hydraulic connections between the different hydrogeological units and the possibilities for water and mass exchange between them. The model has been generated with Modflow computer software. Various options have been developed, varying the boundary conditions and the water conductivity of the main fault disturbances in the area. With each of the developed model solutions, quantitative assessment of the water balance elements has been made and three-dimensional solutions for the flow field are obtained. The obtained results were used for the preparation of prognosis for the occurrence of negative processes of quantitative and qualitative impact on the groundwater and ecological consequences for the upper aquifers in the eventual development of the Dobrudzha Coal Deposit.
