case study

• Geomorphic processes


  Processes that shape the landscape
• Human activity and management

  Combine with geomorphic processes to shape the landscape
• Cow Green reservoir


  1. Controlled the river

  2. Build up of sediment behind the dam

  3. River downstream has less sediment, flows faster

  4. Erosion rates could increase
• Yarm flood prevention scheme

  1. Concrete walls along the river bank to get the water through the town quicker

  2. Increased erosion levels

  3. Gabions introduced to reduce erosion

  4. Embankments raised so the river can hold more water

  5. Downstream flooding more likely
• Teesside river modifications


  1. Mandale Loop cut off, shortening the river by 4km

  2. River dredged to keep it clear of sediment and allow large ships access

  3. Dredged material used for land reclamation

  4. River flows faster
• Tees Barrage


  1. Built in 1995 at a cost of £54 million

  2. Prevents flooding particularly at high tide and in times of storms
