Originally posted by Old Hack View PostHaha, yes, indeed, I am from South Wilts/Somerset border originally so know the area fairly well. Used to live in Southwick, near Frome.Comment

Originally posted by amcdonald View PostExcept Poole Harbour which gets extra tidesPoole happens to be close to a nodal point,
owing to its position approximately halfway
between Lands End and the Dover Strait. In
the English Channel there occurs a ‘Standing
Wave’, rather like the wave you get by slopping
water about in a bath. The pivot point of this
wave is in the vicinity of Poole. Hence there is
a Mean range at Poole of 1.6m Springs and
0.5m Neaps, as compared with 3.9m and 1.9m
respectively at Portsmouth. As you move away
from Poole, so the size of the tide increases.
Interestingly, Portland and Southampton, both
roughly equidistant from Poole, have “mirror
image” tidal curves with a Low Water and a
High Water “stand” respectively. By the time
Dartmouth and Shoreham are reached, again
both fairly equidistant from Poole, the tidal
curve has settled down to the conventional
semi-diurnal curve.
With it so far? Good! Now let us complicate
the matter by introducing friction. In shallow
water, friction causes a distortion of the tide in
such a way that it introduces another ‘standing
wave’ into the cycle. A tidal graph will show it
as a second ‘blip’ on the curve. However, when
the main tide range becomes small, the
frictional effect distorts the tidal curve more
and more, eventually producing either ‘double
high’ or ‘double low’ waters, depending on the
phasing of the tidal curve.
Strictly speaking these are not ‘double highs or
lows’ but a dimunation of the normal twice
daily tide cycle. Where the semi-diurnal tide
range is small, any shallow water tide effect
remains a constant. Hence during neap tides at
Poole, the tide is mostly due to shallow water
tide constituents.
Poole Harbour consists of a large basin with
only one entrance. As described above, the
tidal stream is mainly quarter diurnal. In other
words the stream at the entrance ebbs and
flows 8 times per day as opposed to the normal
4 times per day round the rest of the coast.
Though the tide range is small, even at springs,
the quantity of water that must run out of the
harbour to empty it is very great indeed, which
accounts for the strong tidal streams to be
experienced at the harbour entrance.
So you see, the explanation of the Poole
double tides being a result of two separate
tidal waves reaching the area, one from the
east and one from the west, is entirely untrue,
as is the story that the Poole tides and indeed
the Solent anomalies are due to the presence
of the Isle of Wight.
Hope this helps.
My brain hurts.Science isn't about why, it's about why not. You ask: why is so much of our science dangerous? I say: why not marry safe science if you love it so much. In fact, why not invent a special safety door that won't hit you in the butt on the way out, because you are fired. - Cave JohnsonComment

Originally posted by MarillionFan View PostI'd recommend the new hotel at Cheddar Gorge. £119 with breakfast for a family of four which includes entry to the cave & site for the whole day(and part of the next if you swing it). Then £79 per subsequent night. Good base of operations. Avoid Wookey though, right rip off these days.Comment
