Glossary of Terms

Swash Zone

The zone of wave action on the beach, which moves as water levels vary, extending from the limit of run-down to the limit of run-up.

Coastal Zone

The transition zone where the land meets water; the region that is directly influenced by marine hydrodynamic processes. Extends offshore to the continental shelf break and onshore to the first major change in topography above the reach of major storm waves.

Scarp, beach

An almost vertical slope along the beach caused by erosion by wave action. It may vary in height from a few cm to a metre or so, depending on wave action and the nature and composition of the beach.

A steep slope, usually along the foreshore and/or at the vegetation line formed by wave attack.

Toe

Lowest part of sea and portside breakwater slope, generally forming the transition to the seabed.

Accretion

The deposition of sediment, sometimes indicated by the seaward advance of a shoreline indicator such as the water line, the berm crest, or the vegetation line.

Tropical Storm

A tropical cyclone with maximum winds less than 34 m/sec (75 mile per hour). Compare with hurricane or typhoon (winds greater than 34m/sec).
