Spurn Head (spit)
Negative feedback: cliff collapse debris effect
Negative feedback: cliff collapse debris effect
Protects cliff base from wave attack, slows erosion
Positive feedback from climate change storms
Positive feedback from climate change storms
Erodes beach faster, debris can't protect cliff
Positive feedback from rising sea levels
Positive feedback from rising sea levels
Sediment removed faster than replaced at Spurn Head
