Site 3 has a breakwater and a zone called a groove box is formed in two breakwaters, so the evaluation of mass transfer of trading beach was done at site 3. Sports Area Groyne Box Picture: Sea Wall [IMAGE] 1 2 3 4 5 [IMAGE] [IMAGE] Groyne 1 The purpose of Groyne 2 Sea is to confirm the effect of Longshore Drift for a long time.
At this time, rock fragments from Otakamiro Headland were washed away by the waves, destroyed by wear, and carried along coasts covered as coasts and sand dunes. The movement of this material is called Longshore Drift and the direction of deposition depends on the wind direction. Coastal erosion, coastal transport, coastal sedimentation are the natural processes occurring in Muriwai's coastal topography. These outlined processes form phenomena like Motutara Island (stacking), Otakamiro Point (horn / cliff), fisherman's rock (coast), cave and pore.
Natural changes such as wind, temperature and precipitation can affect coastal sand dunes. The wind brought by wind energy influences the movement of the beach along the beach and contributes to the formation of dunes. Rainfall affects the nature of the vegetation growing on the dunes and eventually affects the strength of the dunes system. The temperature affects the time it takes to get wet from receiving the influence of the dry condition of sand dunes and wave. Constructive winds and destructive winds also influence the size of coastal dunes ecosystems to determine whether sand is added or removed. Global warming and sea level rise are another natural influence of the coastal dunes ecosystem. High temperatures around the world can cause sea level rise, leading to destruction of coastal dunes and their vegetation and erosion of the land. Introduction of alien species has its advantages and disadvantages. Introducing rabbits in Australia has had disastrous results
Continental materials starting from erosion such as sandy beaches, gravels, pebbles etc are washed away to the beach by the beach and river. Two separate processes deposit sand and sediment on the coast. Most sediments are floating in seawater and are carried along the coast by coastal currents. This ocean current is generated by a wave that flows parallel to the beach and breaks at a certain angle with respect to the coast. For coastal transport, up to 1 million cubic yards of earth and sand are carried on a single beach per year. In the second process, the sand deposited by the waves that flowed to the shore vibrates as the waves hit and retreat from the coast. This continuous land-sea movement gradually pushes sand towards the edge of the beach. Coastal coastal shipping and coastal wave movement are part of a process known as coastal drift.
