This document discusses various coastal landforms and processes, their impacts on people, and methods for managing the coastline and tourist activities. It specifically describes rotational landsliding, longshore drift, and different hard and soft engineering options for reducing coastal erosion, including beach nourishment, groynes, riprap, and planting vegetation. It also addresses managing tourist access through designating protected areas, limiting visitor numbers, and building infrastructure like footpaths, fences, and visitors centers.
3. Rotational landslip
Created by the structure of the rocks
in the cliff
Needs to have permeable rock
sitting above impermeable rock.

Extension:
Explain how abrasion at the cliff
base/foot could speed up this process.
Explain the hazards that these
processes could cause.

8. Managing tourist activities – can you explain some different options?
Choose four of these and explain how each one would help manage/control tourist activities.
Create a Site of Special Scientific Interest of Area of Outstanding Natural Beauty and
control how land is used and how and where building are placed.
Limit the number of people who can visit a particular area of the coast.
Have footpaths to control where people can walk, with clear signposts
Fence off areas to prevent people walking across or accessing them.
Build a visitors centre with a car park, to control where people can visit, and provide them
with information and educational material.
Control access to certain times of the year.
9. Managing the Coastline
Beach nourishment
Groynes Planting vegetation
Rip rap
Beach Artificially add beach material
to reduce impact of erosion.
Catch sand and pebbles carried
by longshore drift, and reduce
erosion.
Break up the power of waves
and reduce erosion.
Break up the power of waves
and reduce erosion.
Hold the beach or cliff
together with plant roots.

12. For an area that has suffered from a river flood:
Name the area:
Describe how the flood affected different groups of people:
Explain the causes of the flood:
UK Floods 2012 (River Exe; River Cam; River Avon; River Severn)
Motorists
Homeowners
Farmers
Emergency Services
