Interesting report out today ; projected flood areas

[Capt Popeye]

If the Mods think its OK

Report out today showing in year 2050 the areas of UK where flooding is most likely to happen , naturally due to rising Sea Levels
Quite extensive really , report states that the Govt is not likely to build preventative defences owing to total costs involved ; reports suggests that these areas are most likely to be vacated the inhabitants moving elsewhere
An asside states tat those with a 25 year mortgage are going to be placed in a predicament , sell at what price early or await the outcome ?
Food for tought with us being Boaty Peoples maybe living close to the present Sea Shores ; then Marinas better be paid for by then , me thinks ?

I live at Oxford-on-sea, or will soon.

It's also caused by isostatic rebound following the last ice age. Whilst this effect is better known for previously glaciated land to rise slowly following the retreat of the ice a lesser known effect is nearby land that was not glaciated falls. The south and east of the UK has been slowly sinking for thousands of years. The neutral line in the UK with stable height is approximately Robin Hood Bay to St. Brides Bay. North and West of that, it's rebounding upwards, South and East it's sinking. Good examples of rising land are Chester where the Romans used to sail their ships to the city - now the sea is miles away, and Parkgate on the Wirral where the seawall still has mooring rings, but there's no sea any more.

Am I right in guessing that there is more than the Global Warming having an effect on our apparent coastline then ?

Should this information be more widely spread , if the Report is accurate then lots of Homes , Businesses , Towns etc will be greately effected , some maybe , obliterated alltogether ,

According to the the reports ive read, happisburgh will be under the sea.
Happisburgh is 45ft above sea level... Actually looking at the maps again they've exaggerated it tremendously. If part of a district is likely to flood they've included the entire district, North Norfolk is the highest district in Norfolk a large part is over 100ft asl and includes Beacon hill 344ft above sea level.

Is that the one that shows the whole of cornwall at risk up to the county boundary? So one side of the Tamar Vslley stays dry!

Happisburgh won't be inundated by the sea, it just won't exist. The problem there is coastal erosion. It sits atop cliffs made of basically mud. Rising sea levels & sinking land accelerate the rate of erosion, but the main cause is dodgy geology. I lived there for a while. Every year the road to the cliff edge got shorter.

Yes, although the rate of land sinking in the UK is quite slow, maximum 5cm per century. Another effect is coastal erosion, as is happening in Happisburgh most dramatically. This has been happening on the coast of East Anglia since humans first started living there & long predates any global warming involvement. Towns have already been lost - Dunwich was as big as London at the time when lost 650 years ago. A total of 300 towns & villages have been lost over the past 900 years; it's nothing new. Happisburgh is probably next to go. The guvmint & councils used to try to stop it with sea defences but have given that up now as a battle that can't be won.

Look on the bright side. Out West there's more new mud than anyone knows what to do with. It's just a soft southerner problem ?

 

[The Q]

Yep but that's not the claim, the claim was about flooding..

I can see Happisburgh Lighthouse from my garden, there are a road , a row of chalets, a road, a row of houses , gone in the last 25 years.

Some reasons.. 1991 the local council removed the wooden sea defences as dangerous and didn't replace them. Then new schemes were prevented because two people keep objecting to any new scheme protecting Happisburgh, namely a Professor Keith Clayton and, lord of the manor Eric Couzens,

To anybody living on or near the coast in Kent or Essex this is old news.
The cliffs at Minster on the Isle of Sheppey are good example, the erosion can be observed in months rather than years.
It makes no economic sense to protect much of our coast and we need to use our brains not concrete blocks and sentiment.
Elsewhere in the world it is not usual to build houses on movable platforms ?

Tell that to the Nederlands, it's just that our governments choose not to.. Not enough voters in small coastal villages, millions in London..

The Village of Eccles (just south of Happisburgh pleaded with Henry VIII to reduce their taxes, they were being taxed on the doomsday books record of 2000 Acres, By Henry's time they only had 200 left. Somewhat before " global warming by man"

 

[oldgit]

The Dutch are protecting their entire country and have economies of scale ?.

The report and news articles used the East coast and photographs of crumbling cliffs and houses falling into the sea all of which makes for good alarming stories but is bugger all to do with rising sea levels and GW, it's caused by longshore drift and has been happening for ever or at least since the retreat of the last ice age.

Local TV had a bit on the news last night, the cameraman must have been lying down in order the make the 6" wavelets look at least a tiny weeny bit threatening.

Well OG did you mean 'Floating Platforms' as moveable platforms might float away , ending up in an EU country , then where would them be ? (NB thats a retorical question , please refrain from answering it ? do not want this thread to Modified )

I'm reminded of a Grand Designs build of a house built on floats on the banks of the Thames. If it floods, the house just floats, held in place by piles. Sooner or later, some of those lovely big houses overlooking Chichester Harbour may be wishing they'd done the same. I've thought over the last several years that a riverside or seaside house is a poor investment (Sandbanks anyone?).

I'm alright, Jack. Someone posted a map of what our coast would look like if the water level rose by 40m. The good news is that I'd be able to park the boat at the bottom of the drive. The bad news is that I'd need it to go to Tesco's.

Curious to know how the services (would) work. Sewage might be easy, though...

Ultimately, all flood protection schemes will fail. You don't just have to ask "Will it work?" but also "Who's going to maintain it in 100-200 years time?" Some of the major East Anglian floods arose because of patchwork maintenance of flood defenses. Perhaps worth noting that the deliberate destruction of flood defenses by the Chinese Nationalists during the Sino-Japanese war caused an unknown number of deaths, but probably in the millions, directly or indirectly. Flood defenses will always fail in the long run.; that's why managed retreat is often the best option except in very high-value areas.

Flexible pipes/cables, IIRC.
