"Growing the Beaches"
- the beach exists in a dynamic equilibrium
- the beach acts as a "shock absorber" to ocean energy
- wave energy moves sediments along the coast like a "river of sand"
- sand is constantly moving both on/offshore and alongshore
The dynamic equilibrium of beaches
- the beach adapts to four factors
- when one factor changes, the others adjust accordingly
The beach as a "shock absorber"
- dynamic "buffer zone" that adjusts to changing conditions
- includes the area from the dunes out to deeper water (~30ft)
Seasonal changes in the beach
- summer and winter beach profiles
Offshore transport by rip currents
The beach as a "river of sand"
- littoral drift - sediment transport due to wave action
- from west to east along our coast
