    Its OK mate, I was just being my lighthearted self (never took much very too seriously, lifes too short). I am nowhere near awake enough to contemplate your Boyles Law related question. I didn't even know fridges worked that way, learnt something already. I could have looked it up I guess... Squall and rain here now.

    Morning CK! Reading your post I was smiling and bewildered at the same time, as ever. Then you threw in a curved ball by asking something about the weather. Having now recovered and had a sit down to compose myself, I don't know the answer to your question with any real certainty. But I think the cold weather comes from the chilly parts of the globe which have little sun concentration (aspect). Probably wrong, but its a start. Perhaps a post in the Model Thread to pose the question might be a way forward ? Go on I dare you. Was sunny here, now cloudy. Standard.

    The Brighton sewer tour - highly recommended, they are still available.

    Some big gusts starting now, whistling down the chimney. I'll need to renew our fence soon, but there's 35m each side... so a bit costly. Ours hasn't fallen down yet because its a 'hit and miss' type. Its just rotten.

    A builder friend of mine is putting up loads of concrete fence posts and new panels, good luck to him - he does a good job too,

    He's no use whatsoever to the people he's watched going through misery and lose everything. They always deny resignation, about 48 hrs before they go.

    Great , detailed forecast JP. Thanks Now glued to ice road truckers

    Reporting in from staggeringly bright warm sunshine in Coldwaltham. The flood plains of the River Arun are being well utilised- acres of water with the elevated train line passing through. Those newish elevated houses on the South side of Pulborough were designed with good foresight.

    Lots of love and best wishes to you and yours from many of us here. I am sure that everyone here is with you in mind. i have no hesitation in stating that.Tough times, many of us have been through similar situations i' m sure.

    The differing operators now such as the privatised water companies, the EA, the IDBs etc all have differing funding, investment priorities and the catchment boundaries that the Borough Engineer could not have managed, even if that person was really capable and authoritative. I used to work as a consultant to the EA and even on some flood studies on the River Parrett. Egret, your points are bang on. Its all been looked at and its all manageable, we shouldnt be looking at flooding to this degree whatever the circumstances. Someone's lost the helicopter view, that's for sure and the green lobby has too much power - we have pandered to the EU Regs without consideration for our own interests necessarily. The Levels are being destroyed right now. Thats not the intention, these arent being managed as wetlands effectively. The water levels are controllable however wet it was before the last 7 weeks -the rivers drain naturally to the sea and how the water gets off the land is down to the hydraulics which have all been modelled pretty accurately. Do we have land there below MHWS? I dont know the exact situation as to what the hold up is with the offloading of water right now but my guess is its down to maintenance of the hydraulic structures. CIWEM publishes some good policy stuff and their website is worth a rummage.

    Its surprisingly mild, but its coming from Biscay. Another torrent about to hit London according to the raindar

    So its a snowfest then JP yay Frustration everywhere. MOD thread, EA, somerset levels, Network Rail, it goes on and on And to top it off Bronzed Bob Crow (cor blimey) sounds everso everso sorry (not) for peeing off millions of tube users. Boris bikes had a bonkers day and plenty of moaning from some miserable high end whinger they had run out of bikes... Surely not. Think i'll stay tuned here, everywhere else is in meltdown.

    All very good points and I wholeheartedly follow your views. The way that many wetland areas are managed to the benefit of humans and flora and fauna is to MANAGE the water levels with adjustable weir levels (weir penstocks or sluices etc in some river hydraulics parlance). Just wondering why we are still looking at floods - it must be that case that channels haven't been maintained. Hydraulics of the situation explain it.

    Quite right http://forum.netweather.tv/topic/79214-severe-flooding-in-somerset/?p=2910356

    Metcheck isn't generally rated highly, but their Warnings are OK I think Never seen FOUR published at the same time Metcheck issue a range of weather alerts ranging from Weather Watches to Flash Weather Warnings. The latest alerts will appear on this page as well as a banner displayed across the top of all pages on the website. A description of the type of advisories we issue can be found at the bottom of the page. Click Here to find out how we decide on weather watches and warnings. High Risk Moderate Risk Low Risk No Risk Issued Sun 2 Feb: 17:00 GMT Valid From Tue 4 Feb : 18:00 GMT(Currently Active) Valid Until Wed 5 Feb : 23:00 GMT (3hrs remaining) Weather Watch For Heavy Rain and Severe Gales A deepening Atlantic low pressure system is expected to bring heavy rain and very strong winds across much of the UK during Tuesday night and much of Wednesday. Exact details at this stage are to be determined, but this system could bring rainfall accumulations of up to 1 inch (25mm) across the south and southwest of England and Wales, with perhaps up to 40mm falling in some spots. As a result flooding will once again become an increasing concern following the very wet winter so far. In addition to the rain, very strong winds are expected too with gusts of 60-70 mph possible and perhaps even 80 mph along some coastlines in the southwest. This Weather Watch will be updated on Monday. ---END--- High Risk Moderate Risk Low Risk No Risk Issued Tue 4 Feb: 13:00 GMT Valid From Thu 6 Feb : 12:00 GMT(In 16hrs) Valid Until Fri 7 Feb : 12:00 GMT (40hrs remaining) Weather Watch for Heavy Rain and Gales Confidence is now growing for a new area of low pressure to develop to the South of the UK during Thursday and push slowly North-east. Heavy rain is expected across much of South-west, South and South-east England as well as South and Central Wales coupled with gale force winds across the South-west and later the Eastern half of the UK. This heavy rain will extend North-east towards Central and later North-east England. Between 20-30mm of additional rainfall is expected widely across much of England and South and Central Wales between 12pm Thursday and 12pm Friday. ---END--- High Risk Moderate Risk Low Risk No Risk Issued Wed 5 Feb: 09:00 GMT Valid From Fri 7 Feb : 18:00 GMT(In 46hrs) Valid Until Sun 9 Feb : 12:00 GMT (88hrs remaining) Weather Watch for Heavy Rain and Severe Gales A new active area of low pressure (expected to be Storm Ruth) will push in from the Atlantic during Saturday bringing very similar conditions to those experienced on Tuesday/Wednesday of this week across much of England and Wales. Heavy rain will push in ahead of gales and later severe gales on Friday evening across the South-west with Saturday seeing gale force to severe gale force winds across Western areas. Disruption to travel and power is possible with the increased risk of loosed topsoil falling trees. ---END--- High Risk Moderate Risk Low Risk No Risk Issued Wed 5 Feb: 09:00 GMT Valid From Mon 10 Feb : 00:00 GMT(In 100hrs) Valid Until Mon 10 Feb : 18:00 GMT (118hrs remaining) Weather Watch for Heavy Rain There is currently low/moderate confidence of an area of heavy rain pushing into South-west and Southern England during Monday morning. Current model guidance shows an additional 10-20mm of rainfall along the Southern counties. However, recently models have pushed these disturbances further North and increased intensity and this system cloud follow that pattern. This watch will be upgraded or removed as the situation becomes clearer. ---END---

    Plenty of people would like to strangle Beeching right now. Used to be more resilience to the network. Probably seemed like a good idea at the time........

    Yes, all unreinforced masonry, segmental or granular will move 'inelastically' ie. move a bit and then be permanently displaced. Then they get displaced a bit more and then accelerate towards their doom ! Elastic structures move back to their original position, so retain their form, within limits of course. The wall's been there a long time, but met its match today. It'll be rebuilt of course but I stand by my comment that more of it will go before they get to fix it - judging by what the weather experts on here say. There may be some alleviation if there is a Westerly or northerly wind component, - off the land. Sorry for the houseowners, horrific mess.

    Indeed. pretty epic stuff. http://forum.netweather.tv/topic/79252-atlantic-storms-february-2014/?p=2918715

    Just spoke to my Mum and Dad who live in Dawlish, fortunately up near the top of a hill. House still has its roof. She's never seen so many camera crews, even some foreign ones. Police preventing access to the seafront. Being a chartered civil engineer for the last 23 years and looking at that failed structure, there isnt a lot to it when waves come over the top. Hydrostatic loading on the back , no tensile strength, granular backfill and over she goes !!
  24. fluid dynamic
    Yes 4 to 6 weeks worth of work, not unreasonable "off the top of his head" I would say, and he didnt say when they would start !

    I think there will be a fair bit more sea wall dissappear along there in the coming week. Its always been thought of as a rubbish place to put a railway line, but its rather hilly around there so difficult to find an alternative. Very pretty train ride along there though.
