Year 12 Measuring River Variables


For homework and the lesson I am away at camp I have asked you to look into the fieldwork you might conduct if you wanted to measure river variables. Below are some links that you will find useful. For each variable you should:
1) Define the variable
2) Describe the method of measurement for this variable, including the equipment you would need.
3) Any calculations you would need to do in order to achieve the results.
4) Discuss any potential problems with this approach.
Use diagrams where appropriate.

(reminder of the variables: stream width, depth, bank-full width, cross-sectional area, discharge, gradient, velocity, internal friction, external friction, rock or pebble size)

The Geography site - offers an excellent, easy to understand summary of the techniques.
Journey along a river on this website - it is worth surfing around this site as it has some excellent summary pages of the aspects we have been covering recently.
Try Geography High - a virtual geography school!
Why not try Thinkquest - also good for revision
