Excellent replication potential across the entire semi-arid Mediterranean dryland zone. Key factors supporting replication: (i) the geophysics-guided design protocol is technology-agnostic and can be applied with widely available instruments (ERT, TEM) found in university and research institute laboratories across all RESWATER partner countries; (ii) the construction materials (gabion mesh, concrete, HDPE geomembrane) are available locally in all target countries; (iii) the community governance model (Water User Associations) is proven in analogous contexts in Tunisia, Morocco, and Jordan; (iv) comparable wadi and ephemeral stream networks exist in Malta (Wied systems), southern Spain (Murcia and Almeria ramblas), Greece (Crete seasonal streams), and Türkiye (Mediterranean coastal wadis).
