Abstract Groundwater return flow to streams is important for maintaining aquatic habitat and providing water downstream users, particularly in irrigated watersheds experiencing scarcity.

Water scarcity in the Mediterranean region requires adoption of new and optimized water resources management tools that allow a progressive climate change adaptation, being one main drivers for employment alternative storage measures such as Managed Aquifer Recharge (MAR). To promote implementation these measures, this study evaluates application MAR feasibility index mapping to southern Portugal, employing Multi-Criteria Decision Analysis (MCDA). A participatory approach – developed within AGREEMAR project aims characterization intrinsic site suitability, availability demand, where stakeholder inputs are embedded weighting computation process. The results obtained demonstrate prevalent moderate across entire (78% area) with an increased percentage area corresponding high (22%) strongly related highly suitable geological features. comparative analysis Analytical Hierarchical Process (AHP) showed minor areas (7%), class transitions between directly above or below classes. sensitivity analysis, conducted based on one-at-a-time (OAT) variation criteria weights, assessed impact methods changes. For method, changes weight 10 28 considered resulted negligible when compared original map, while AHP 3 out produced remaining important modifications maps, which underlined method weights provided higher stability results. provides information about selection process procedures, allowing replication. dissemination is expected raise awareness among stakeholders support scientifically-based decision-making.
