you could always go for a Tufa-one and put the sponges in the drains. (moved onto names of rocks, for a spot of variety) |
|
| |
Huge sponges affixed to the outside of seawalls might also
help absorb kinetic energy from incoming tsunami. |
|
| |
Not living right on the shoreline has been
found to be 100% effective as a protective
measure against both tsunami and
hurricanes. |
|
| |
These drains... how big? I'm assuming that a modest
tsunami is enough to dump at least 10 metres of
water on a band of land at least 100 metres inward of
the coastline. |
|
| |
// at least 10 metres of water on a band of

|
| |
And the rest… the tsunami from Krakatoa
were 50m high and ran up to 5km inland. |
|
| |
Hence the merits of the "live somewhere
else" approach. |
|
| |
//Not living right on the shoreline...tsunami and hurricanes |
|
| |
That just leaves the earthquakes,typhoons and tornadoes and then you're right in the schist. |
|

Got bored of trying to find the tsunami that zapped south-west England circa 10,000 years ago, there's a fault-line off south-east (?) Ireland..it's on the net somewhere..anybody know the URL? |
|
| |
You forgot blizzards, landslides, avalanches, and country
music, all of which can also be the cause of National
Emergencies. |
|
| |
There was a tsunami that flooded the Severn in
the early 1600s, that killed about 2000 people. |
|
| |
There's also evidence that a landlocked body of
water in present-day Norway/Sweden broke out in
a landslide about 8-9000 years ago, cutting England
off from the European mainland, in a rush of
water. |
|
| |
Similar events associated with meltwater from the
receding ice age seem to have occurred in North
America and from the Mediterranean into the
Black Sea, through the Dardanelles Strait. |
|
| |
Can you imagine how deep the oceans would be if
sponges had never evolved? |
|
| |
//sponges had never evolved |
|
| |
So what we really need is a crash-breeding program of sponges to counter the sea level rising. |
|
| |
// cutting England off from the European mainland// |
|
| |
Surely you mean 'cutting the European mainland off
from England' ? |
|
| |
And a jolly good thing it was, too. |
|
| |
Yes... can you imagine what a fucking mess we'd be
in if Blair and Brown had been running all of Europe
for the last ten years? |
|
| |
Or if Thatcher had had all of Europe to herself for the
1980s? |
|
| |
Without Thatcher, ice cream would have been a lot
runnier. Really. |

It's one od those sad ironies of history that Charles" Non! " De
Gaulle and The Divine Margaret ("She Shall Rise Again! ") missed
one another by just a couple of decades. |
|
| |
That would have been a discussion worth watching (from a
concrete bunker some tens of kilometres away, rather like
Trinity…) |
|
| |
so even the borg get colds.. |
|
| |
Just thinking... if vulnerable shorelines were
populated by Netherislands-style dockable homes
that could be released when the wave hits, perhaps
locking to other homes, the resultant rafts might be
safely carried inland until the wave loses momentum.
Hence more survivors. |
|
| |
Only among those who end up on top, as it were. |
|
| |
Whatever works... I don't think I'll ever forget seeing
that car sink in the Sendai whirlpool with the driver
desperately looking up at the helicopter. |
|
| |
I'm trying to imagine the scale of a system capable
of absorbing or moving the top ten meters of the
ocean in one location for 10 hours. |
|
| |
Let's look at 10 meters of coast for simplicity. You
have a 10x10 meter pipeline being filled at a flow
rate decided by the speed of the incoming current
and water pressure. I believe the second
measurement is high enough to render water
movement speed almost irrelevant. If only I had
payed more attention in vector fields class... |
