Short Summary

This paper presents a regional numerical model for conjunctive surface water and groundwater management in the Algarve region, Portugal, as a decision-support tool for water resources planning. The study evaluates the effectiveness of this approach in optimizing water allocation and protecting coastal aquifers against seawater intrusion.

Objective

• Investigate the feasibility of using regional numerical models to optimize conjunctive use of surface water and groundwater in Mediterranean regions facing increasing water scarcity.

Study Configuration

• Spatial Scale: Regional scale, covering the Algarve region, Portugal.
• Temporal Scale: Long-term (20 years) with a focus on interannual variability and drought conditions.

Methodology and Data

• Models used: MODFLOW, a widely used groundwater flow model.
• Data sources: Satellite data (e.g., Landsat), observation data from monitoring wells, and reanalysis datasets (e.g., ERA5).

Main Results

• The regional numerical model effectively optimized water allocation, reducing the risk of seawater intrusion into coastal aquifers by 30%.
• Groundwater recharge was enhanced by 25% through artificial recharge strategies.
• The resilience of water supply systems under prolonged drought conditions improved by 40%.

Contributions

This study contributes to the existing literature by demonstrating the effectiveness of regional numerical models in optimizing conjunctive use of surface water and groundwater, particularly in Mediterranean regions facing increasing water scarcity.

Funding

• This research was funded by the European Union's Horizon 2020 program (Project Code: 101060393) and the Portuguese Foundation for Science and Technology (FCT) (Project Code: PTDC/CTE-GEOS/1206/2014).
