They do - sometimes - then you might end up with "Oxbow Lakes" formed in the process.

Rather minor environment damage compared to the HS2 genocide i would have thought,which the media don`t make much issue with.

Genocide?
https://en.wikipedia.org/wiki/Genocide 

Seems a bit harsh for the kind of thing that the Victorians (e.g. Brunel) did all over the country, which we know and love and protest most strongly when it is destroyed.

I believe there were plans to reinstate the classic Cuckmere meanders, but then the pandemic struck. I'd like to see that.

It seems I was not entirely correct - the concept was (or is) to bow to the inevitable, and restore the area that contains the cut off meanders as estuary, as sea levels slowly rise, it becomes more and more difficult to maintain the status quo.

"Genocide" is a little harsh I agree but HS2 is in my opinion not comparable to the Victorian works of art that we admire today.
The Victorians thought big, spent big and built big. There was as much time/money/effort invested in design as there was in quality.
These days the cream goes on consultants and newt fences and ticking boxes. The construction is all subbed out to the lowest bidder while Principle Contractors take an ever larger slice. When you get to the actual product every part is designed and built down to a price and built with little concern for quality.

And that is such a huge shame. When you do the sums, it's about £1,000,000 per meter to build HS2. For that sort of money, you would expect the most fantastic construction, but no, it all goes on 'other stuff', like legal fees, judicial reviews, eco this, natural that, ancient the other', so the amount left for the actual railway is a pittance.

When discussing the new A14 project in this neck of the woods, one of the contractors said it was basically a Health and Safety demonstration that had the side effect of building a new road. I'm sure HS2 is even worse.

Comparing cutting done scrub tree`s and shrubbery and moving the gravel on the river bend to cutting down a vast number of tree`s hundred`s of years old.
The only problem i see with that river job,better if the farmer had left some of the gravel near the bend,as the flow of that river is going to accumulate more gravel there in time,and the old way of taking gravel from the sand banks in rivers caused less damage than what one see`s these days.

I know. I remember learning that in geography back in the 1970s. My point is though, that new meanders form or else rivers would be a series of straight lines between lumps of erosion resistant rock.

Me too! I was tempted to put a tribute to my fondly remembered Geography teacher. He was a Marmite type person, you either thought he was great, or a right *******. I fell into the former group.

The Cuckmere oxbows were formed by an artificial cut. I imagine it's rare to find natural oxbows in this country of any size due to the amount of river management we have had for hundreds of years, mainly for navigational purposes. Natural ones form when a meander gets so tortuous, the river cuts through the narrow neck of land it has created.

Not sure it does actually. The bulk of major river management work in the past I suspect was for passage of boats and the like when water transport was the lifeblood of the economy. Plus land drainage when nobody gave a toss about the massive changes this would have, as long as it freed up land to grow stuff, regardless of the degradation caused. There are few places in the UK where this is true nowadays. In the fens we have benefited till now but are there not serious problems with soil condition and the like, and peat erosion etc. I won't state there are, as I am no expert (see earlier bit of the discussion).

I cannot think of any man-made ox-bow lakes.

I have heard the Cuckmere meanders called oxbows (which they aren't really I suppose) - they were isolated when the river was straightened. Technically they may not be "oxbows" - but they are static stretches of water where once a tidal river flowed, cut off by the course of a river changing/being changed.

It would appear some local volunteers have intervened to channel water back to improve the meander water quality.
