Hi Marc,
Thanks for the post!
I've gone by riverboat along stretches of it. Down at Dhaka in Bangladesh
it's known as the Meghna River.
The riverboats there sink with monotonous regularity :-

It's deceptive when you look at the delta region on a map or even on
a satellite image in that you see all this area you perceive as land.
When you fly over it at lower altitudes, it strikes you that it is all
water with just tiny patches of land raising a few feet - and at
times only inches - above the water level.
So it is a prime target for rising sea levels due to climate change and
the amount of inundation during the monsoon will only get worse.
There are a lot of people there. I was nearly crushed to death in a crowd
there once. Where they will have to relocate will be one of this
centuries great challenges.
