Short summary
In this paper, we postulate a possible evolution of the groundwater salinity around a village in southwestern Bangladesh, based on high-density fieldwork. We identified that the thickness of the surface clay layer, the surface elevation and the present-day land use determine whether fresh or saline groundwater has formed. The outcomes show how the large groundwater salinity variation in southwestern Bangladesh can be understood, which is valuable for the water management in the region.
