Abstract: The ever-increasing demand for water resources, coupled with excessive groundwater extraction, has led to a significant decline in aquifer levels (Lopez-Alvis et al., 2019). As a result, there is a pressing need for innovative solutions to replenish and restore these depleted aquifers. Managed Aquifer Recharge (MAR) has emerged as a promising technique to address these challenges and enhance water availability, contributing to sustainable water resource management (Dillon et al., 2019). In this context, GIS-based multi-criteria decision analysis has proven to be a valuable tool to identify suitable regions for MAR implementation (Sallwey et al., 2019). These suitability maps consist of physical factors relevant to the MAR objective, particularly hydrogeological characteristics, water availability, demand for groundwater-dependent services, and non-physical considerations such as economic viability, social acceptance, environmental impacts, and legal constraints. This work proposes a stakeholder-adapted methodology for creating feasibility maps for MAR via the integration of GIS tools and multi-criteria decision analysis.
