Hydrogeological characterization of the salt ponds environment in Saelices de la Sal (Guadalajara, Spain)

摘要

The salt evaporation ponds in Saelices are a site of Cultural and EcologicalInterest Site inside the Alto Tajo Natural Park. Time ago the saltygroundwater was pumped out from two wells. It has been proved that thissalinity is due to the discharge of groundwater from Keuper facies. This saltywater flows up into the alluvial sediments of the Arroyo de la Vega. It is a Na-Cl type water with a high electric conductivity (higher than 25 mS/cm). Thissalty water gets mixed with fresh water (coming from rain and from adjacentquaternary sediments) inside the alluvial sediments and flows into the Arroyode la Vega channel
