surely Griff if you dredge the river, the water will flow out quicker, but will also flow back in quicker, and will still be dependent on the water level at Breydon, I can see the case being made by the non dredgers, that if the flow was clearer, then salt water incursion would be worse. we have clearly seen over the weekend that the river level can drop rapidly, but only when the sea level in the north sea also drops, so I am afraid my mind has been changed - by mother nature. I would still advocate dredging to keep the navigation clear across the width of the rivers and on the bends, but I no longer think this would drop the river levels to the extent we had supposed.
seeing the effects of the low water at Brundall and other places where most of the boats were aground, I am thankful in a small way that this tidal range isnt seen as badly on the northern rivers.
I do wonder what the levels were like above Potter Heigham Bridge over the weekend, for instance was hickling broad still navigable, what variation was there due to the low tides at that location.
I like some others am beginning to think this is far more complex than we supposed, and that there isnt a simple fix that wont make matters worse in some respect or other, somewhere.
