Coastal areas are characterized by considerable demographic pressure that generally leads to groundwater overexploitation. In the Mediterranean region, this situation is exacerbated a recharge reduction enhanced climate change. The consequence water table drawdown alters freshwater/seawater interface facilitating seawater intrusion. However, salinity may also be affected other natural/anthropog...

Abstract Over the past decades, fractured and karst groundwater systems have been studied intensively due to their high vulnerability nitrate (NO 3 − ) contamination, yet nitrogen (N) turnover processes within recharge area are still poorly understood. This study investigated role of karstified in NO transfer by combining isotopic analysis nitrite 2 with time series data hydraulic heads specifi...
