Glossary of Terms

Those currents which flow roughly parallel to the shore and constitute a relatively uniform drift in the deeper water adjacent to the surf zone. These currents may be tidal currents, transient, wind-driven currents, or currents associated with the distribution of mass in local waters.

For navigational purposes, the term is used to designate a current in coastwise shipping lanes where the tidal current is frequently rotary.

Erosion

The loss of sediment, sometimes indicated by the landward retreat of a shoreline indicator such as the water line, the berm crest, or the vegetation line.

Marker, reference

A mark of permanent character close to a survey station, to which it is related by an accurately measured distance and azimuth (or bearing).

Outcrop

A surface exposure of bare rock, not covered by soil or vegetation.

Pebbles

Beach material usually well-rounded and between about 4mm to 64mm diameter.

Seagrass

Members of marine seed plants that grow chiefly on sand or sand-mud bottom. They are most abundant in water less than 9m deep. The common types are: Eel grass (Zostera), Turtle grass (Thallasia), and Mantee grass (Syringodium).
