Spurn Head

• is located on the Humber Estuary on the East
  Yorkshire Coast.
• It has a classical shape with a hooked end.
• How long and how wide?
• Why doesnt it grow over the estuary?
• How did it come to be?

Erosion of Boulder Clay on the Holderness section
of the coast

When is and isnt it eroding?

Sediment in the sea

Longshore drift

• Longshore drift is the movement of material along
  the beach in a zig zag pattern.
• The swash approaches at an angle to the beach
  pushing the sediment with it.
• The backwash pulled by gravity drags the beach
  material back into the sea where the process
  repeats.

Evidence from groynes

Creation of Spurn Head

• For a spit to be created there needs to be
• longshore drift occurring plus
• there needs to be shallow and sheltered water and
  
• lastly a change in the shape in the coast line

12
Has it always been a spit?

• Spurn Head is cyclic which means that it goes
  through a 250 years of creation and destruction.
• But people have built homes along the coast which
  means it will need protection from erosion.

13
How do we protect?

• Spurn head is cyclic which means that it goes
  through a 250 years of creation and destruction.
• But people have built homes along the coast which
  means it will need protection from erosion.

14
How do we protect?

• This is also a form of protection it is a
  concrete wall which should stop wave damage but
  is it effective?
• Hard approaches

15
How do we protect?

• What other protection could be used?
• Softer approaches

16
Protect one place erode another
17
Summary

• The main features of deposition are is a very
  long spit the most noticeable is Spurn Head on
  the Holderness Coast.

18
Make a sketch

• Draw a location and sketch map of Spurn Head and
  explain how it was formed - a storyboard is a
  good way of doing it.
