RESEARCH PRODUCT

The regional park of the Nebrodi Mts. (Sicily): a contribution to an integrated groundwater management

subject

description

The Nebrodi Park, located in the north-eastern sector of Sicily, is of particular environmental and scientific interest. This is due to the morphological heterogeneity of the protected region that presents a wide variety of landscapes and ecosystems. In spite of the recent efforts of the Regional Government and Municipalities, environmental resources, especially groundwater, risk progressive depauperation and pollution. In this paper, the authors consider the hydrogeological karst unit of Monte Traura-Rocche del Crasto, the most productive in the Nebrodi belt (zone B of the regional park). This unit is underexploited and needs a careful hydrogeological study in order to supply coastal aquifers. Geochemical and geophysical prospecting has been carried out in this area. Analyses of water springs, sampled in different seasons, have suggested patterns of groundwater circulation. Apparent resistivity measurements have yielded complementary information about the recharge processes of deep aquifers. Goals of the project to which this research belongs are the rational exploitation and protection of reservoirs such as Monte Traura and the recovery of the degraded aquifers, proposing new strategies of regional management for the water resources in this comer of Sicily.
