Abstract

The Prats de Sant Sebastià wetland is located in Caldes de Malavella, on the northeast of the Iberian Peninsula. Several zones with anomalously high ground conductivity have been identified at this site. As a result of local high salinity, rare, highly specialized plant species grow in this area. The geophysical data to 6 m depth show saline soil concentrations in a north-south direction. The hydrogeological setting of the wetlands provides an insight into soil genesis and the origin of the wetland environment. It was deduced that discharging groundwater from underlying hydrogeothermally deposited salts produced and maintains soil salinity in the wetland. The locality is little known, and until now, there were few hydrogeological data available.
