Flow rates on the Wiza

There was awful flooding on Station Road last May when the Wiza overflowed after a day of torrential rain - see photographs at the bottom. And yes, that is a man canoeing down the road. Since then they have installed a pole for measuring the depth of the water. Fluid dynamics, which covers the flow of water, is a branch of Physics. And the foundations of any good scientific study is good data. So hopefully this new piece of measuring equipment will help to provide the data to prevent further flooding. Note that road level is about 2 metres 20cm. In other words, the water would have been above my head on flood day.
