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

Aim
Investigate downstream changes along the river Glendettera Beck in comparison to the Bradshaw model
