Objectives
• To integrate environmental isotope methods into a joint approach for studying groundwater salinization
• To develop environmental isotope-based models of salinization dynamics for data scarce coastal aquifers
• To combine environmental isotope methods with physical-based and numerical models for calibration and validation
Description of work
The work package focuses on the development, application, and integration of environmental isotopes to identify the source, dominant processes and degree of salinization. This work-package includes research on existing methods of environmental isotopes and the scientific transfer to the problem of groundwater salinization in the Mediterranean. Isotope sampling campaigns will be carried out in all study sites for a broad range of environmental isotopes for residence time analysis (14C, 3H, SF6, CFCs), for origin assignment (18O/16O, 2H/H, 13C/12C, 15N/14N, 11B/10B, 87Sr/86Sr of intruded seawater and for identifying the dominant hydro-chemical processes (Ca/Mg, Sr/Ca, 87/86Sr, 11B/10B, Br/Cl, B/Cl). The work package will deliver an integrated approach applicable especially in data scarce regions to rapidly recognize and detect, identify, and assess salinization mechanisms.
