This project focussed on the development of a conceptual model for the geological processes and response behaviour of Asian mega deltas, which are affected by strong monsoons, high river flow and sediment load, and frequent geo-hazard events. Existing databases were integrated based on the input of many experienced Asian delta scientists, each of whom has been working with specific geological issues that include subsidence from groundwater withdrawal, sea-level rise impacts, and coastal erosion, saltwater intrusion and river channel dry-up from damming and water diversion.
