Tide predictions for the Scullers' head

Here's what I predict (for Corney Reach). Given the very early high tide
there should still be some appreciable stream for the event.

These are for average flow conditions at Teddington (respectively time,
height of tide (m), stream rate (m/s))

29/11/2003 9:0 2.1 -0.66
29/11/2003 9:10 2.0 -0.65
29/11/2003 9:20 1.9 -0.65
29/11/2003 9:30 1.8 -0.65
29/11/2003 9:40 1.7 -0.65
29/11/2003 9:50 1.6 -0.64
29/11/2003 10:0 1.5 -0.64
29/11/2003 10:10 1.4 -0.64
29/11/2003 10:20 1.3 -0.64
29/11/2003 10:30 1.2 -0.63
29/11/2003 10:40 1.2 -0.63
29/11/2003 10:50 1.1 -0.63
29/11/2003 11:0 1.0 -0.63
29/11/2003 11:10 0.9 -0.62
29/11/2003 11:20 0.9 -0.62
29/11/2003 11:30 0.8 -0.62

And these are for twice November normal stream conditions as I gather
it's been a bit wet down there in the last few days

29/11/2003 9:0 2.3 -0.73
29/11/2003 9:10 2.2 -0.73
29/11/2003 9:20 2.1 -0.73
29/11/2003 9:30 2.0 -0.73
29/11/2003 9:40 1.9 -0.72
29/11/2003 9:50 1.8 -0.72
29/11/2003 10:0 1.7 -0.72
29/11/2003 10:10 1.6 -0.72
29/11/2003 10:20 1.6 -0.72
29/11/2003 10:30 1.5 -0.72
29/11/2003 10:40 1.4 -0.72
29/11/2003 10:50 1.3 -0.72
29/11/2003 11:0 1.3 -0.72
29/11/2003 11:10 1.2 -0.72
29/11/2003 11:20 1.2 -0.72
29/11/2003 11:30 1.1 -0.72

 
 
 

Tide predictions for the Scullers' head

as it's continued to rain here's the predictions for 3 times normal
November flow rate at Teddington (216m3/s)

29/11/2003 9:0 2.6 -0.79
29/11/2003 9:10 2.5 -0.79
29/11/2003 9:20 2.4 -0.79
29/11/2003 9:30 2.3 -0.8
29/11/2003 9:40 2.2 -0.8
29/11/2003 9:50 2.1 -0.8
29/11/2003 10:0 2 -0.8
29/11/2003 10:10 2 -0.8
29/11/2003 10:20 1.9 -0.8
29/11/2003 10:30 1.8 -0.8
29/11/2003 10:40 1.7 -0.8
29/11/2003 10:50 1.7 -0.8
29/11/2003 11:0 1.6 -0.81
29/11/2003 11:10 1.6 -0.81
29/11/2003 11:20 1.5 -0.81
29/11/2003 11:30 1.5 -0.81

which tends to indicate that if there's a lot of land water the later
starters will be better off, although 0.02m/s only amounts to 5 secs
or thereabouts.

sorr,y can you explain what these numbers mean? not the date and time bit
... the next bit.

Thanks,

Upriver here in Oxford there's still hardly any stream - well below normal
November flow rates.
Maybe people downstream have been drinking a lot of beer recently?

Date and time

Your core body temperature in C as you start marshalling.

Your chances of winning, given your core body temperature.

IIRC, the columns are date;time;depth of water in m;water speed in m/s
(negative in this case because the water is flowing out).

sorry was in the original posting. It's the height of the tide above
chart datum (which approximates to the lowest astronomical tide) and the
speed of the stream in m/s (-ve because the water is flowing towards the
sea)
