Geography Fieldwork
-
Data presentation
Scatter graphs
These are better suited for comparing data, as they clearly show how quantitative data increases or decreases downstream along the river
Tables
These can be used to quickly see and understand specific values, if you want to see depth, width or velocity at a specific point on the river
-
Data collection
Qualitative
Non statistical data which usually cannot be measured with a set piece of apparatus and can be subject to bias
Velocity
Hydroprop flow-metre
Timing a small impeller moving from end of a screw to the other, dividing 3.2805 by this value, and adding 0.0277
-
Depth
Metre stick
Placing one end of the metre stick on the river bed and measuring the distance between the bank and the surface
-
Reliability
Our results weren’t very reliable, as our data collection methods were susceptible to human error, and our equipment was reasonably simple
We only collected data on a single day, so our results did not factor in the effects of seasonal weather or characteristics changing over time
