Cyclones in a Changing Climate : The Case of Bangladesh

This paper integrates information on climate-change, hydrodynamic models, and geographic overlays to assess the vulnerability of coastal areas in Bangladesh to larger storm surges and sea-level rise (SLR) by 2050. The approach identifies polders, coastal populations, settlements, infrastructure, and...
