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.

This was constructed to protect the headland from further wave erosion and to ensure the pedestrian pathway stayed open for access to the headland. The wall is ____________metres long and was built in _________. * Processes affected: The main processes affected are wave refraction‚ wave erosion and coastal transportation. The waves refract around the headland and attack the sides of the headland. Because of the sea wall the

Sand Dunes The Importance of Vegetation Sand dunes are a valid indication of the quality of the soil and the surrounding ocean. When vegetation is established in sand dunes‚ it stabilises it- i.e. gives the dunes structure. This structure helps prevent erosion by using the plant life to trap the sand. Without these plants (and ultimately the sand dunes) sand will be subject to many natural forces without protection‚ meaning any major storm could theoretically remove large amounts of sand from

My written report on coastal management will revolve around the main issue explored in our field trip which is the gradual erosion of the foredune on Collaroy beach‚ and its effects on stakeholders (incl. residents‚ developers‚ specialist groups). This report will also include the decision making processes considered by the management (both local and state)‚ as well as the descriptions

many different designs; it can be used to protect a cliff from wave attack and improve slope stability and it can also dissipate wave energy on sandy coasts. Challenges /Limitations /Disadvantages However‚ a seawall may not protect a coast from erosion in the long run. As waves break against the seawall‚ the curved sea walls reflect the energy of the waves which is redirected downwards‚ to the base of the seawall‚ resulting in a strong backwash. The backwash wears away the base of the seawall‚ causing

erosive power of waves To protect a coast from erosion‚ people have built seawalls in front of a cliff or along the coast. A seawall is usually made of concrete. It acts as a buffer and absorbs energy of breaking waves especially during storms where the waves are strong‚ thus protecting the coast. A seawall shields and protects the coast from the direct impact of the incoming waves‚ thus reducing erosion. However‚ a seawall may not protect a coast from erosion in the long run. As waves break against the

Growing up‚ the end of October typically meant playing soccer and finding a costume for trick-or-treating‚ but in 2012‚ my community became saturated and preoccupied by the anticipation of a coming storm. Although northern New Jersey is not normally where hurricanes violently meet land and its inhabitants‚ the weather pattern became apparent that we were not going to escape this one. On October 29‚ Hurricane Sandy began to embrace and ravish everything impeding its chosen path. Instead of soccer

happening of erosion on the sand dunes and rocks on the coastline of Terrigal and Wamberal. Some people have caused more pressure on these areas as they have built housing such as at Stop 7‚ “The Ruins” Wamberal South. Many of the people that lived on the beach have tried to find ways to stop most of the erosion from waves and wind affecting their land and housing. On the beach we saw many strategies that are effective in their own ways but not permanent. One way was to plant vegetation on the sand dune
