GEOLOGICAL AND HYDROGEOLOGICAL CONSIDERATIONS ON THE PHREATIC AQUIFER OF THE TÂRNAVA MICĂ RIVER FLOOD PLAIN AND TERRACES

Abstract

Geological and hydrogeological considerations on the phreatic aquifer of the Târnava Mică river flood plain and terraces. The project „Enhancement of Water Resources Management in Mureş River Basin" target is the development of an instruments set and of a methodology on a sustainable management of surface and groundwater resources from the Mureş river basin. Thus, there has been selected as a pilot area, the Târnava Mică river basin (as sub-basin of the Mureş river basin), for which it was developed a mathematical hydrological integrated model.The phreatic aquifer located in the flood plain and terraces alluvial deposits of the Târnava Mică river basin represents a source for the localities water supplies (fountains) and for the economic agents (wells) from the area. Because of this reason, the groundwater from this aquifer is an important element in the balance of water, and also for the integrated management of the water resources from the study area.The paper presents some geological features (lithology, facies variations) and hydrogeological (hydrostatic level variation, dynamics, etc.) of the phreatic aquifer, as elements of a better knowledge of the phreatic aquifer from the Tarnava Mica flood plain and terraces.
