An interesting discussion at work a few weeks ago, or was it in the bar at the last meeting?
That although 1 million tons of mud have been removed, none of the area was drying ground, and the rise and fall will be the same as before [all above the new depths.
So would the volume of water moving through the entrance not be the same as before and therfore also the speed of flow?
Can someone answer before Mike, but I look forward to reading his views
