What are landscapes as dynamic systems?Show answer
Coastal and glaciated landscapes are open systems. When a disturbance (a storm, sediment loss, a new sea wall) shifts the balance, negative feedback tends to restore equilibrium, for example a beach drawing down in a storm then rebuilding as constructive waves return sediment. Positive feedback amplifies the change instead, for example cliff retreat exposing more weak rock to erosion, which accelerates further retreat. Understanding which feedback dominates is the key to judging whether a landscape will recover or continue changing.
