Terrigal-Coastal Management
Part 1 The geographical processes that are occurring at the Terrigal beach area are: * Erosion, which is effecting: * The Skillion, mainly the headland and rock platform, which is part of a preserved area of land known as “the Haven” which also contains the rugby oval. The man type of erosion that affects this is from the sea. * The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The main type of erosion, from the sea, takes the sand from the sand dunes as well as the rest of the beach in a rip. The sand is then pulled out to sea where it forms a sand bar. On calmer days, the sand is brought back to the beach. * Storm damage can affect coastal properties. This is especially made obvious when buildings are constructed on sand dunes. When the sand is taken, the result on the houses is catastrophic. * Lagoons, which are formed where sand deposits to form a baymouth barrier at the entrance to a bay, either partially or fully, blocking it off. Here, either the lagoon can access the sea during high tide or it can be closed for the majority of time, only accessing the sea when a tidal inlet forms.
The main human activities that are impacting the Terrigal beach area are: * Building on sand dunes - when the dangers of building on sand dunes were not known, the council sold the land and allowed people to build on it. This lead to the destruction of a large amount of houses. This area is now known as the ruins. * The development of urban areas and facilities. These include: * The rugby oval at the foot of “the Skillion” * Roads * The boat harbour at the headland * A commercial area near the beach * Residential areas * The retaining wall (this is positioned at the edge of the beach in order to prevent sand and sea water from entering the commercial area) * The development of these facilities results in a changing landscape and
