Sensitivity analysis of multiple groundwater vulnerability models for enhancing resource management in the Menzel Bourguiba aquifer system, northern Tunisa

Key Points

• Key findings indicate significant variations in groundwater vulnerability metrics across multiple models, highlighting inconsistencies.
• The analysis showed that specific parameters, such as land use and recharge rates, influence vulnerability assessments significantly.
• This observational analysis utilized multiple groundwater vulnerability models to evaluate their sensitivity and reliability.
• Potential limitations exist due to the regional focus, stressing the need for broader validation beyond a single aquifer system.
