You have experienced geographical fieldwork as part of the course. Use the experience to answer these questions.
(a) (i) State the aim of your investigation and describe one method of data collection associated with the aim. (6)
We repeated this 3 times in the middle of the channel, 3 times on the left bank and
3 times on the right bank to find an average as the velocity varies across the channel.
We did speed = distance/time to find the velocity and multiplied it by 0.8 to cancel
out surface friction
The person upstream released a dog biscuit and shouted so the downstream person
could begin timing.
The upstream person made sure they weren’t obstructing the flow.
To test the relationship between velocity and hydraulic radius downstream of the
River Ise and suggest reasons for our findings.
Dog biscuit technique was used to calculate the velocity needed to see if there was
a relationship with HR stated in the aim.
Firstly we measured a 10m distance downstream and marked it out with ranging poles
and had one person at each end.
When the dog biscuit reached the downstream person they stopped the timer and
recorded the result.
