Stratified (Stream Order)
Split up the sampling into layers or catergories (Enforces bias)
1 of 10
Systematic (10 meters apart)
Sampling done in a regular way
2 of 10
Random
Least biased Adv: Can be used with large population sizes Ddv: Chosen coordinates may be inacsessible
3 of 10
Hydraulic radius
River efficency
4 of 10
Key Facts
Distance downstream from 1.8m to 2.4m Wetted perimeter from 3.1 to 6.7
5 of 10
Why was it a suitable area?
River channel near study centre, two steep slopes lonscale + blease fell v-shaped valley could therefore see downstream changes quicker due to increased discharge from SRO, rock type impermeable ground pre-trodden quicker run off.
6 of 10
Why was it a suitable area?
High annual rainfal
7 of 10
Aim
Investigate downstream changes along the river Glendettera Beck in comparison to the Bradshaw model
8 of 10
Secondary Source Data
Met Office, data. Enviroment agency data. A different river study data.
9 of 10
IV and DV
