I don't know paladine but this is the message from the EA that comes with the e mail.

Due to the continuing north westerly winds causing tide locking, we are expecting to see increasing salt levels in the River Thurne over the next few days.

Thank you for the replies. It rather seems to be a mixture of  meteorology and chemistry - weather prediction followed by water analysis.

The following link is a thread from another forum (no not that one) and I think you will see from the photos posted yesterdays tide was particularly high due to the weather conditions.
Wind speed and direction is one of the main causes.

And today's tide here at Potter is even higher than yesterday's with another three hours yet to flood. The Thurne is overtopping the flood defences in the usual places and, doubtless, the IDB pumps will be pumping it from the marshes back into the flooding river!

The output of some of these pumps can be quite ferocious. Perhaps the outfall pipes could be fitted with mini hydro-electric thingies, to offset the cost of the electricity they use.

It's tidemill at woodbridge on the Deben, at normal low water it's mostly a sea of mud there with a trickle down the middle, the marina behind the mill has a cill to keep enough water in so boats can stay floating.

I still do not understand how the barrier keeps the saline out as the water goes around the ends of the barrier and the water is always the same level each side of the barrier perhaps someone could enlighten me,we moor  in wood,s marina.

Hi Adrian

I also wonder how it works, noone I speak to seems to understand the science .

I do think it restricts some water though as the marina at our end never seems as high as the river itself with the barrier in place

The other thing I don't understand is where are all the fish resting  . I have placed fish  finders and cameras under our boat when the barrier is in place and always seen diddly squat , but they may of course be in another basin

Because fresh water is less salty and less dense than water from the ocean, it  floats on top of the heavier seawater.

my appearance is down to me, my attitude is down to you.

I also moor in HW basin, and have fished while the barrier is up without getting a bite - i assume the fish must have gone upriver under the bridge… Playful Wink

With kind regards
