Tidal lagoon plan appears set to fail in 'dirty' estuary...

experience with the Kariba and Aswan dams may act to provide a historical comparative ?

And we have seen what happens when Dean and Dyball built Watchet Marina and failed to make provision for silting by not using the outflow of the Washford river.



How does Cardiff deal with the problem caused by impoundment by the lock gates, or is the depth slowly decreasing ?

Dredging every few months.

If you mean siltation of the freshwater bay behind the lock gates, this is not particularly a problem as the silt is (largely) not coming down the Taff/Ely rivers. In the Bristol Channel the silt is, broadly speaking, going round and round in the Severn Estuary. So the siltation problem is associated with areas of marine slack water- e.g. watchet, the seaward approaches to Cardiff Bay, that sort of thing.
 
I said from day one it was a waste of time and money because of the silt in the Bristol channel,
They should have asked me first and give me the money they gave to these so called professors lol
