Here is the link to the 2009 pictures http://www.michaelsbookshop.com/surge/ apologies that a couple of them have become corrupted, I will put them right when I can find the original files, the moral here being don’t move you web hosting from Windows to Linux.
Several factors determine how high the waves will get in a storm, once again there are different ways of expressing the height of a wave, I will use the one called significant height, this is the height difference between the trough between the waves and the crest on the waves.
One factor is the strength (speed) of the wind, I will express this in knots, nautical miles per hour, a nautical mile is a little bit longer than a statute mile.
In the days of sail sailors measured the speed of their ship with a line with equally spaced knots tied in it and a lump of wood on the end. One of them dropped the bit of wood over the side and counted how many knots passed through his hands, while another one timed this with a glass, something like a big egg timer with sand running through it.
Another factor is the duration of the storm, the longer the wind blows for the higher the waves, this has a saturation time after which the waves don’t get any bigger.
Another factor is the fetch of the sea, this is how far it is between the shores along the line of the wind direction.
In the 1953 tidal surge 1,835 people were killed in the Netherlands and 307 were killed in the United Kingdom and about 250 people were killed at sea.
A problem with the sea is that it has waves, I suppose the fact that it killed over 2.500 people in this part of the world during one storm, is a testament to this.
