I have a new paper, led by Jess Raff, that analyzes sediment transport and sediment budgets in the Ganges-Brahmaputra-Meghna delta, and assesses the implications of sediment flow for sustainability in the face of sea-level rise and the diversion and damming of major rivers.

Bangladesh's geography will naturally counter sea level rise until it becomes too rapid due to climate change

I was interviewed by the Dhaka Tribune on the impact of sea-level rise in Bangladesh. I explained that with good land-management, sediment carried to the coast by the Ganges, Brahmaputra, and Meghna rivers can raising the land as fast as the sea is rising for the near-future, but that eventually global warming may cause the sea level to rise faster than the land can adapt.
