IDROGEOLOGIA DELLA BASSA VALLE DEL FIUME ESINO

Abstract

After a brief description of the geologica! setting of the middle and lower part of Esino hydrographic basin, we describe the main hydrogeological characters as: - the meteoric precipitation with elaboration of isohyet maps; the thermometry; the evapotranspiration and the elaboration of hydro­logic balance; - the climatic regime; - the geometry of the unconfined acquifer entirely contained within the continental deposits represented by four main alluv.ial terraces; - the reconstruction of the seasonal freatimetric with the groundwater flow and the historical variation of the water table; - the seasonal variation of conducibility and temperature of the groundwaters.
