Case study of a river catchment at local scale: key themes, field data, impact of precipitation on drainage basin stores and transfers, implications for sustainable water supply and/or flooding
A river catchment is an area of land that drains into one river. You study real field data to understand how rainfall moves through that catchment and what that means for floods and water supply.
Real World
The River Exe catchment in Devon was studied after the 2012 floods, when saturated peat soils on Exmoor could no longer absorb rainfall, causing rapid overland flow that overwhelmed Exeter's flood defences.
Exam Focus
Link field data directly to specific stores and transfers — examiners reward correct use of systems terminology over generic description.
