An Integrated Hydrogeological Modelling Approach to Evaluate Groundwater Resources of Sarmatian Hydrostructure from the Moldavian Platform, Romania

Abstract

Ignored until now for their hydrogeological potential, in the conditions of current climate changes, the Sarmatian deposits in the Moldavian Platform, Romania attract the attention of researchers aiming at the objectives of Romania's long-term security strategy. Vital resource, underground water, significantly affected by global climate changes, calls for regional management strategies that must be based on detailed hydrogeological research of storage, recharge and protection conditions under the impact of natural and anthropogenic factors.Integration of contaminant migration is the current, highly effective approach for evaluation of groundwater resources used as the source of tapping groundwater supplies for a large part of urban and rural agglomerations.The Sarmatian hydrostructures from the Moldavian Platform, with a high level of vulnerability to pollution, are the subject of our integrated hydrogeological modelling, in which the vadose zone is the main complex objective. Using our Integrated Hydrogeological Modelling we achieved the coupling of the contamination migration from the soil, the vadose zone and the phreatic Sarmatian hydrostructure in several areas (Huși, Vaslui, Botoșani).The quantitative evaluations carried out on the conceptual 3D models of the SARMATIAN hydrostructures were carried out using the classic tools: ROCKWORKS, SESOIL, VS2DT, MODFLOW.
