Comparing Barmston Drain outflow in 1873 and now. The width of the water and the height of the banks show how much silt there is.
In my opinion these two pictures show the whole problem in Hull. Nowadays we can control the tides entering the rivers so clearing the drains and the rivers should solve most of the problems.
There is a ‘wilded’ area up Barmston that does not help.
Holderness drain has similar problems.
