How To Read Water

A New York Times Bestseller – A Sunday Times ‘Must Read’ book

A RIP CURRENT

From Chapter 15:

Rip currents are feared and much misunderstood. They get called ‘rip tides’ frequently, but they are not a tidal phenomenon, and this is just the start of the confusion that they seem to create. The physics is actually very straightforward, rip currents form when a wide area of water on the beach is pulled back to the sea by gravity, but finds a narrow channel to flow through. Water will accelerate whenever it passes through a narrower gap – like when you put your thumb over a tap or the end of a hose – and so a fast current that flows out towards the sea is formed. They can flow at two metres per second, faster than any swimmer.”

DIFFRACTION

From Chapter 12, on Reading Waves

“Any waves passing through a narrow gap in a barrier will fan out.”

THE HOLE

From Chapter 6 on Rivers and Streams:

You can imagine that one of these holes on a big scale is something to be very wary of in a small craft and getting caught, sandwiched between the two flows, is every kayaker’s nightmare – they have killed many people over the years. But once we know what to look for, we can revel in seeing them on a much smaller scale. Some of the most mesmerizing ones I’ve seen were smaller than my hand. Holes are such important features of white water that they have many other nicknames, including ‘hydraulics’ and ‘stoppers’, but I prefer ‘holes’ as it reminds us what is going on beneath the surface.”

A GLITTER PATH

From Chapter 10 on Light and Water

This long line of shimmering reflections is known as a ‘glitter path’ and is caused when our eye picks up thousands of tiny sun reflections of the sides of waves stretching into the distance. The shape of the glitter path is a measure of how high the sun is and the roughness of the waves. The glitter path will get narrower as the sun gets lower and broader as the waves get steeper.”
