Rivers 1

First, find your river ...

Then learn how to measure it ... 

Width ...

Depth ...

You cannot measure the length!

Velocity (with an impeller - not an impala on a stick!)

Velocity with a cork ... If lost the cork must be replaced with a new one surround by a bottle of Rioja ...

And write it all down ...

Lunch at the cricket ... At site 2 anyway.
