Thank you.
Just to clarify, we did measure boat wake waves from pleasure craft, including wake boats and the cruiser, that were up to 15 centimetres. I wouldn't necessarily classify those as small waves. When they hit the bank, you could see that they stir up the sediments quite a lot.
If you tried to measure the bank recession from one of those waves, it would not be measurable; it's too small. You do have to see it over a period of time, which is why I surveyed the bank both this year and last year, and we'll do it again next year. In fact, we've looked at satellite imagery. We've seen that it's been receding over a couple of decades at about the same rate.
Does that help?
