Abstract
This research makes a comparative analysis of reduced upstream discharge, sea level rise, and cyclonic conditions to find which factor predominates in the impacts of salinity intrusion. Findings show that a reduced upstream discharge causes increased saltwater intrusion in the entire region. A rising sea level causes increased salinity in the shallower coast. The cyclonic impact on saltwater intrusion is confined within the landfall zone. Salinity intrusion through the estuaries in low-lying tide-dominated deltas is a serious threat. Different levels of impacts are evident in the Ganges-Brahmaputra-Meghna (GBM) delta and along the Bangladesh coast.
