Coastal landforms
type: Concept
definition: Coastal processes refers to the action of natural forces (e.g. erosion, deposition, tectonic uplift) on the shoreline, and the nearshore seabed. Some examples of landforms resulting from these processes are wave-cut cliffs, beaches, and wave-cut benches.

Spit
type: Concept
definition: A deposition landform found off coasts. A spit is a type of bar or beach that develops where a re-entrant occurs, such as at a cove, bay, ria, or river mouth. Spits are formed by the movement of sediment (typically sand) along a shore by a process known as longshore drift. Where the direction of the shore turns inland (reenters) the longshore current spreads out or dissipates. No longer able to carry the full load, much of the sediment is dropped. This causes a bar to build out from the shore, eventually becoming a spit.

Tombolo
type: Concept
definition: A deposition landform such as a spit or bar which forms a narrow piece of land between an island or offshore rock and a mainland shore, or between two islands or offshore rocks. They usually form because the island causes wave refraction, depositing sand and shingle moved by longshore drift in each direction around the island where the waves meet. Eustatic sea level rise may also contribute to accretion as material is pushed up with rising sea levels.

Environmental impact of recreation
type: Concept
definition: Recreation and tourism are often accompanied by extensive damage to the environment. Aquatic ecosystems are particularly vulnerable to the effects of an increased tourist trade and the resultant building of hotel accommodations, sewage disposal works, roads, car parks and landing jetties on banks and coastlines; and the increased angling, swimming, water skiing, shooting or use of motor-boats in the water body. These all produce direct deleterious effects when conducted on a massive scale, including shore damage, chemical changes in the water, and sediments and biological changes in the plant and animal communities.
