Lack human development
Cliffs v.susceptible to erosion despite weak constructive waves

Q
Why were gabions needed and how effective?
A
To stop undercutting of cliffs + not effective but created new habitat
5

A
Cliffs = out of boulder clay if become saturated lubricated + mass movements occur
Pipe removed water from cliffs stopping saturation
