Question 15

15. What were the results from your Dorset fieldwork?

Answer 15

The beach at Swanage had a much shorter width than that of Studland which had a greater distance from the sea to the sand dunes.
The Beach at Studland also had a shallower gradient than that of Swanage.

Swanage has mitigated against the risk of coastal flooding by having hard engineering solutions such as sea walls and groynes.
However, some of the groynes were not maintained well particularly as you moved away from the main town area.
You could also see the flow of sand being reduced due to these groynes as there was more sand on the one side of the groyne than the other.
Studland had a more natural coastal defence with the sand dunes as it is a nature reserve.

Question 16

16. What were the results from your Oxford fieldwork?

Answer 16

The largest flows of car traffic were as you moved away from Oxford City centre.
There was only bus and taxi traffic near Carfax as this is where the greatest amount of shoppers would be and this part of Oxford cars are not allowed.
There was also greater amounts of both car and bus, taxi traffic near to Oxford Train Station as well as the Pitt Rivers museum these areas are just outside the no car zones.

Oxford has mitigated against the risk of river flooding by hard engineering solutions of channelisation near folly bridge, Osney lock and weir, Raised and reinforced banks, alleviation channels.
Soft engineering solutions to mitigate against the risk of flooding in Oxford floodplain zoning port meadow.
