Dynamic equilibrium
Dynamic equilibrium
State coastal systems gradually move toward over time
Marine processes
Marine processes
Sea-driven: waves, tides, longshore drift
Sub-aerial processes
Sub-aerial processes
Land processes: weathering, mass movement, run-off
Sediment budget
Sediment budget
Balance of sediment added vs removed from coast
Positive sediment budget effects
Positive sediment budget effects
Shoreline builds seaward, features grow, beach levels rise
Negative sediment budget effects
Negative sediment budget effects
Shoreline retreats, erosion, beach material loss
