Bangladesh has to worry about rain-fed flooding on top of coastal flooding

• ncmncm 5y ago
  It might be worth noting that the Ganges/Padma, Brahmaputra, and Meghna rivers combine and drain to the sea in Bangladesh. So, a dike would need to confine not just the sea, but the combined rivers; or you would need a really phenomenal pump, probably orders of magnitude larger than has ever been constructed. It is not easy to find out the annual water flow exiting to the sea from that system. And, it is not the only one.

    Building dams to slow down rivers has never been a problem in europe, why would be in Bangladesh ( i'm talking about the idea, not the money)

      Really? Have you looked at the topography of Bangladesh? A dam 200 miles wide flooding 100,000 sq mi of Bangladesh and India seems to cause a bigger problem than rising seas (until it silts up, anyway). And all the water coming in behind the dam still has to go somewhere, once it's full, anyway.
