In this report I will look at coastal landforms under the categories of erosional,
depositional and sub-aerial landforms. I will show my understanding of the
different types of processes and how they relate to specific landforms that
have been identified.
I have chosen to focus on Old Harry's Rocks on the Dorset coast in Studland as
my erosional landform because this is significant in understanding what soft
and hard rock causes through differentiation erosion.
I have also chosen to focus on Orford Ness in Suffolk. This shows the deposition
of longshore drift and the landforms that develop over several hundred years.
Along the Norfolk coast, I am also looking at the effect of rotational slips in
West Runton. These are usually known as slumps are due to water collection
between permeable and impermeable rock.
I will also suggest possible impacts of the on-going development of the
landforms which can be both positive and negative.
Erosion wears away the land and therefore leaves it
with less material. There are four types of erosion:
1. Hydraulic action ­ Where a wave pounds
against rocks and cliffs and wears away the material
because of the sheer force of the water.

2. Attrition ­ Is where the load collides with each other and grinds away. This leaves the
rock smooth and eventually will result in sand particles being made.
3. Abrasion or Corration ­ Where the waves throw rocks at the cliffs. A similar concept
to hydraulic action but it is the rocks as well that are causing the damage.
4. Solution or Corrotion ­ Where rock is dissolved into the water.…read more

The location that I am focusing on is Orford Ness. This is located on the Suffolk coast
between Aldeburgh and Felixstowe. This is an example of a cuspate foreland shingle spit,
which has formed through the deposition of longshore drift.
The sediment from the beach is carried a distance before being deposited. This is dependent
on the size and weight of the load as well as the type of rock.…read more

Rock fall
Soil creep
Rock/mudslide
There are many more of these appearing along
our coasts because of the changes in climate
throughout the year.
There are solutions to stop it such as drainage
systems and pipes that can be built into the
vulnerable and known areas that slump. This has
a negative impact on the development as it costs a huge investment from the local
government to save the area.…read more
