Inhaltsangabe:
- <p>This study examines coastal water salinization in the Bengal Delta, where saltwater intrusion, sea level rise, tidal flooding, storm surge, and human-driven land use changes have intensified freshwater scarcity for coastal communities. Combining hydrogeochemical analysis and geospatial techniques (GIS), the study identifies Na⁺, Cl⁻, Mg²⁺, and SO₄²⁻ as the dominant ions governing coastal water chemistry, with sea-controlled ion exchange as the primary process. Spatial analysis reveals salinity gradients increasing from north to south and east to south, with the highest concentrations in the southern Bengal Delta — closely linked to the Sundarbans mangrove forest and the Bay of Bengal. Based on these findings, the study proposes nature-based strategies to mitigate increasing salt concentrations in surface and groundwater resources across the delta.</p>
