Yeah, so? That river was completely dredged about 10 years ago, and
they have gone back and done additional dreging in trouble spots since
then. There was a pretty big dredging there of the entrance channel in
2008. It's not like so many other harbors that haven't been dredged at
all since the 1960's.


Your point is the river requires frequent dredging?


That depends on the number of old cars and bicycles
at the bottom.
It maybe also depends on the amount of other
sediments carried downstream.
In my country the first reasons are the most important
in urban areas, boatloads of bicycles around Amsterdam.
