Echo echo echo echo ..................... In one sense, there is an echo, . . and it's the echo of you being corrected about the twaddle you keep posting about river dredging procedures and practices. What is it that compels you to repeatedly post wildly misleading bullshit on the almost infinite number of subjects you know little to nothing about. ? This from July this year : < thunderboat.boards.net/post/245573/thread > . . . . . and a few weeks on, here you are again, dishing out another helping of the same sort of tripe as before !

When I was a lad, people with experience related to their usually manual based work protected it with scorn, piss taking etc directed at those that hadn't acquired that lifetime of experience. With the internet that rug has been pulled out from under the feet of these unhelpful twats and in most cases that type of info and experience is readily available from those that are not twats. Turns out in nearly every case that those unhelpful piss taking obnoxious twats were protecting their vast "knowlege" because it was smoke and mirrors in the first place and they're left stranded on their island (see what I did there ) of now useless experience hurling abuse at anyone passing by. Luckily with each new generation there are less of these twats because there are less and less areas in life that are not open to anyone with interest to learn, but still there are some twats desperately clinging to that time when their pathetic knowlege was king - hurling abuse instead of kind explanations. Twat.

Twat. You're obviously someone whose personal inadequacies have left you with an enormous chip on your shoulder and a deep resentment of anyone who hasn't had to live with the same handicap. On the assumption that your [signed] post was directed at me, and that you didn't bother to read the post I put in a link to at the top of this page, or couldn't open the link, does this following post of mine from last July qualify in your opinion as 'hurling abuse' or a 'kind explanation' ?

They just let it go, to flow down stream if they are spot dredging. and : Yes, at the pinch points. But the immediate problem is solved, which is what cart are all about.___________________________________________________________________________ - and to which I replied : No, that's simply not so, . . except for the all too infrequent occasions nowadays when C&RT make a token effort to remove the mud and silt build-up from ABP's waters in the lock tail at Keadby ! Why post vague, misleading, and remotely factual generalizations which come nowhere near to answering a specific question on how C&RT have previously disposed of the vanishingly small amounts of material they have dredged from sections of the Trent during the time for which they, . . God help us, . . have been the navigation authority ?
Maintaining a dredged to minimum depth navigation channel in the Trent from Wilden Ferry - the upper limit of navigation at Shardlow - to Gainsborough Bridge - the lower limit of Trent Navigation Company, British Waterways, and now C&RT's jurisdiction is, and always has been, a complex and multi-faceted process which until the cessation of the last of the river's commercial traffic on the lower reaches in July 2013 was always complimented by the natural scouring action of the river's run-off current and the (Ebb) tide and the regular disturbance of riverbed silt and sand by the passage of deep-draughted commercial traffic.
The practice of 'spot dredging' was never really applicable to the Trent in the same sense as it was used on canals to clean out the shallow spots adjacent to lock scours and where streams, drainage channels and feeders routinely carry land run-off silt into the waterway every time it rains. Prior to BWB's progressive abandonment of routine maintenance dredging on any part of the Trent - which began in earnest some 35(+) years ago - the closest form of routine maintenance 'spot dredging' practiced on the Trent was the urgent and immediate removal from the lock tails at Holme, Stoke, Gunthorpe, Hazleford, Newark (Bottom Lock) and Cromwell, the sand and silt deposited by the floodwater in the lock tail back-eddies, and this process always began as soon as the river level dropped to no more than 4' - 5' above normal immediately below each of the affected locks.
Except for Cromwell Lock - for obvious reasons - the material removed from the lock tails immediately after any serious flooding events was dumped back into the river just above the next downstream weir, ready to be carried away further downriver by the current during the next serious floods. Formerly this was done using drop(bottom)-hoppers, and in later years from hoppers emptied with a craneboat secured close to the weir crest. For preference, so that the larger proportion of the deposited material was carried away by the next serious flood over the far end of the weir and away downriver instead of simply being carried over the lock end of the weir and re-deposited in the lock tail, the 'dropping down' bollards situated above all the Trent weirs were used to secure the craneboat, rather than the bullnose bollard at the top end of the lock-islands.
The majority of the Trent, including the 26 miles from Cromwell Lock to Gainsborough was routinely dredged, with a fleet of three bucket dredgers - Top, Middle, and Bottom Dredgers - permanently allocated to and working on different sections of the river. Natural scouring by run-off water, or the Ebb plus run-off water, assisted by the passage of loaded commercials, kept most of the total mileage of navigation channel deep and clear, and the dredgers were stationed for lengthy periods at locations where waterborne sediment, including gravel in times of especially severe flooding, was known to consistently settle out due to reductions in the speed of the Ebb and the current brought about by changes in the river's cross-section and bed profile. During each lengthy spell at these carefully chosen locations a large deep hole, sufficient to hold many thousands of tons of waterborne sediments was dredged out in the river bed to act as a reservoir for the material which the river would deposit there prior to the return of the dredger several months later. All the material dredged from the river by the bucket dredgers was transported to and unloaded into designated dredging tips at Gunthorpe, Hazleford, Cromwell, and Marton.

I know you're an imbecile because I'm judging by your standards which are - There are things that I'm expert in but you know nothing about, ergo you're a moron. I do realise you try to ape the wonderful Nigel's prose but your atempts are laughable. In his case the words were neccessary, in yours it's just meaningless over wordy garbage. I expect you think everyone's fooled but it's clear from this and other forums your disguise is transparent. Idiot.

I thought that short piece about river (Trent) dredging would probably be a bit much for you to digest, . . or to decide if it amounted to 'hurling abuse' or 'a kind explanation'. You do seem to be getting perilously close to the 'hurling abuse' you claim to despise in others, . . but at least that will allow you to add hypocrisy to the lengthy catalogue of your other failings.

I wonder how much more respect and support you would have garnered by now had you managed to refrain from the abuse you scatter like a blunderbuss? Still, too late to explore that possibility now.

It's so ironic that you can't get rid of inland waterways dredgings for love nor money but reasonably large ships go out 24/7 dredging the sea bed for aggregates.
I wonder if there is some sort of message here.
Inland waterways are pointless, perhaps.

It seems to me that when the energy crisis intensifies, such questions might be reconsidered. Because if an engine that runs on oats can move 30 tons...just not fast enough for a society contemplating delivery of consumer goods by drone though.

The eventual aim is to deliver contagion by drone while those with the wherewithall disappear to Mars for a bit.
This Covid bollocks is a practice run.
You ain't seen nothing yet.
Of course it will take a while to develop the required systems for the evacuation to be feasible. Meanwhile let's experiment with drone delivery and a spot of light virus sharing.
The funny thing about it is that the internet anorak billionaires think they will end up being allowed through the air lock.

Don't you think the moon is a much more feasible target?
