Case Study : The river Tees

1. Upper course : Cow Green Reservoir

   • Built in 1970
   • Built mainly to provide water for the growing industries on Teeside
   • It traps heavy rainfull and water from snowmelt and allows water flow to be regulated downstream

2. Lower course : Yarm's Flood defence scheme

   • Flood defence scheme costed £2.1 million
     • Reinforced concrete walls with metal flood gates for access by people and vehicles
     • Earth embankments
     • Gabions to protect walls and embankments from erosion
     • Fishing platforms, street lighting and replanting to improve the environment
     • Building materials approved by English heritage to remain in keeping with existing architecture
   • Landforms formed from deposition of fine grained sediment, eg. silt and clay
     • Flood plains
     • Levees
       • Formed when floods carry sediment out of the river (by suspension) and deposit it close to the river

3. Found in Northern England

4. Waterfall is called 'High Force'

5. Meanders and oxbow lakes are found close to Yarm

6. Levees and floodplains are found near Middlesborough

7. Estuary is found in Stockon-on-Tees

8. Upper Course

   • erosional landforms
     • Waterfalls
       • High Force
       • Forms as the water goes over the hard Whinstone rock onto the softer sedimentary rock
     • gorges
     • Interlocking spurs
     • Rapids

9. Middle course

   • Landforms formed as a combination of erosion and deposition
     • Meanders
     • Oxbow lakes
