Q

The Tees estuary is?

A

wide with mudflats and sandbanks, formed by sea-level rise at the end of the last ice-age.

22
Q

Flooding has caused?

A

the development of raised banks (levees) along the lower course - for example near Neasham.

23
Q

Where is the source of the River Tees?

A

The source of the River Tees is Cross Fell in the Pennines.

24
Q

Describe the relief of the River Tees in the upper course?

A

In its upper course, the River Tees flows over hard, impermeable rocks. Vertical erosion has formed classic V-shaped valleys. The image below shows interlocking spurs close to Cauldron Snout.

25
Q

What are the features of the waterfall in the River Tees?

A

The UK’s largest waterfall, High Force, is located in the upper course of the River Tees. An area of hard rock, called Whin Sill (or Whinstone), is located above a layer of soft rocks (sandstone and shale) and together they create the waterfall.

26
Q

Describe the relief of the River Tees in the lower course?

A

As the River Tees reaches its middle course lateral erosion overtakes vertical erosion and is evidenced by winding meanders. Meanders in the lower course are much larger. Oxbow lakes have formed in some areas. Evidence of past flooding can be seen in the natural levees that have formed.

27
Q

Describe the relief of the River Tees in the middle course?

A

In the lower course, The River Tees has a large estuary with mudflats and sandbanks.

28
Q

Describe the location of Lyme Regis?

A

Small coastal town South coast of England

29
Q

What coast does Lyme Regis lie on?

A

Jurassic coast

30
Q

What are the issues Lyme Regis faces?

A

Rapid rates of coastal erosion and landslides e.g. the old road from Charmouth to Lyme Regis which ran across the top of the cliffs above the town

Landslides/landslips - Lyme Regis is built on a layer of limestone, which is very solid. On top of that layer are slippery muds, clays and sands, which slide over the limestone layer to form the landslides. These are all types of sedimentary rocks

31
Q

How has the coastline been managed?

A

The Lyme Regis Environmental Improvement scheme

32
Q

Who was the Scheme set up by?

A

West Dorset District Council

33
Q

What were the Aims of this scheme?

A

To Provide long term coastal protection

34
Q

When was this?

A

early 1900s

35
Q

How were these conflicts reduced?

A

There were consultation meetings were everyone were kept inform

36
Q

What defence has Lyme Regis put into place?

A

Sea Wall

37
Q

What is phase 1 of Lyme Regis development

A

Date 1990 - New seawall and promenade built to the east of the moth of River Lim

38
Q

What is phase 2 of Lyme Regis development?

A

Date 2005 - 2007 - extensive improvements to sea front(construction pf new sea walls and promenades)

39
Q

What is phase 3 of Lyme Regis development

A

Not Undertaken - plan was to prevents landslips (however cost outweighed the benefits

40
Q

What is phase 4 of Lyme Regis development

A

Date 2013 - 2015 - Focused on the coast east of the town(Constructing new 390m sea Wall)

41
Q

What were the prices of phase 1?

A

2003-2004 £1.4million

42
Q

What are the positive outcomes of the developments?

A

Visitor numbers and seafront businesses are thriving

43
Q

What are the negative outcomes of the developments?

A

Some people believed that the new defences have ruine the natural landscape

44
Q

What were the prices of phase 2?

A

£22 million

45
Q

£20 million

47
Q

Where is banbury?

A
  • SE England within 1 hour drive of London, Birmingham and Oxford

Flood in Banbury?

A
  • Major flooding in 1998 costed £12.5 mil
  • River Cherwell that flooded
  • 350ppl forced to evacuate
49
Q

Managing risk of flood?

A
  • A361 raised so flooding doesn’t disrupt traffic
  • Floodwall built around Motorsport company
  • New pumping stations built to pump flood water/ rain water out of town
  • Flow control structures, Hardwick and Huscote flow control structures built to control amount of water in River Cherwell
  • Embankment made of soil made, 4.3m high
  • Biodiversity action plan (BAP) habitat with ponds, trees and hedgerows (encourages water intake by plants and animals, slow up rate of water transfer, reduce risk of flooding)
50
Q

Social impacts?

A

+ve : house owners no longer worried abt damage to property
+ve : new footpaths and parks surrounding flood water storage for families and dogs, improved quality of life

51
Q

Environmental Impacts

A

ve : new biodiversity plan increase vegetation, trees, hedges, pondsto reduce risk of flooding, improving environment
-ve : during construction of flood water storage, heavy machinery damaged nearby vegetation
-ve : soil removed for embankemtn will distrupt habitats and wildlife

52
Q

Economic Impacts

A

ve : contruction was expensive, at £18.5 mil
+ve: construction jobs created in process as well as some jobs to maintain biodiversity plan
+ve : estimated that storage scheme has saved £100mil in avoiding damages
