Abstract

The coastal aquifer near Ravenna (Italy) contains mostly brackish and saline water (Antonellini et al; this volume; Mollema et al., this volume) that is not suitable for drinking water but supports the ecosystems in the natural areas (Antonellini and Mollema, 2010). The current salinization trend will become worse in view of climate change (Mollema et al., 2012). The large volume of the aquifer (2,5x109 m3) however, perhaps allows for the aquifer to be used for low enthalpy geothermal resources development. The temperature of the groundwater in the top layer of the aquifer (surficial zone) is sensitive to the changes in atmospheric temperature throughout the year while the temperature of the deeper groundwater follows the geothermal gradient (Anderson, 2005). One of the scopes of the project is to discover which part of the aquifer has a constant temperature throughout the year. A constant temperature is needed for storage of heat at low enthalpy. Groundwater temperature was measured during December of 2010 and June of 2010 in 56 piezometers placed in the coastal dunes of Marina Romea and Ramazzotti, the Paleodunes with pine forests of San Vitale and Classe, and the farmland in between the dune belts.
