Evaluating groundwater vulnerability to seawater intrusion in the coastal region of Bangladesh

Key Points

• Groundwater vulnerability to seawater intrusion significantly increases due to environmental factors in the coastal region.
• The vulnerability assessment identified 40% of the coastal area at high risk of seawater intrusion, affecting freshwater sources.
• Assessment using hydrological modeling techniques demonstrated spatial patterns of vulnerability across the region.
• Findings highlight the need for improved groundwater management strategies in vulnerable coastal areas to mitigate risks.
