River Tillingbourne Trip

Year 7 visited four points on the River Tillingbourne. At each point we measured the length of the wetted perimeter, the gradient, the speed of the river flow, the bedload and the impact of people (such as litter) to get an idea of the characteristics of the river. We enjoyed using lots of equipment that was very new to us but definitely fun to use, including clinometers, ranging poles, tape measures and metre sticks. Our favourite experiment was measuring the water flow using dog biscuits. During the trip we even found a crayfish and a horse sucking leech! Even though we were all wearing washing up gloves and getting wet in the river, it was really fun to spend the day doing geographical tests.
