We arrived, armed with wellies ...
We learned about the location of the river and how it fitted into the Wey Drainage Basin and also into the Drainage Basin of the River Thames.
We collected some equipment ...
We then went off on a quest in search of a river that needed measuring ...
... and we found one ... the River Tillingbourne. We measured the width, average depth, wetted perimeter, velocity and gradient of the river at three locations.
Site 1: Crossways Farm |
We measured float velocity much to the bemusement of the local equine population. |
We measured the velocity with a hydro-prop flowmeter, which involved having to look up numbers in a table just like in the days before electric gizmos. |
Site 2: Abinger Hammer (Great place name) |
Site 3: Shere |
Watch out for the crayfish! |
We then returned to the centre to crunch the numbers and prepare for our write up day tomorrow back at school.
A huge thank you to the staff of Juniper Hall for looking after us ... we had a great day and learned a lot!
