Ever wondered how many grains of sand there are on a beach?

Over 100 state-of-the-art instruments to record water levels, flow speeds, rates of sand movement and beach change have been deployed so that for every wave that runs up the beach, the instruments will give information on the transport of sand in the water column, the movement of the seabed itself and the net change in the beach shape.

Counting the grains of sand and watching them as they move will allow the scientists to model how the waves erode the beach, second by second and will eventually allow them to characterise which waves cause most coastal erosion.
