Muriwai Dissertation

Muriwai is situated on the western coast with the north tropical isle New zealand and is around 40km via Auckland town, The two normal processes let me talk about that interact happen to be long shoreline drift and Aeolian vehicles and deposition. Long shoreline drift is a process exactly where sediment is usually moved along a seashore by the actions of waves. When the surf approach a beach, the camp of the surf drags over the sea pickup bed picking up sediment and triggering the wave to break, the wave after that swashes up onto outdoors face transporting sediment with it. Gradually the increase of crud pushes the sediment in the beach which usually it is then able to dry up to become lumination enough to become deposited further more up the beach front. The yeast sediment found at southern region muriwai seashore is made up of 3 types, Silica, quarts and titanomagnetite, Silica and quarts are lighter grains using a lighter shade where as titanomagnetite is a darker black color and a heavier feed. At southern muriwai seashore silica and quarts are simply on the top levels of the shorelines sand, this means that the process of Aeolian deposition can take place. For this reason changes to the environment have been capable to take place, such as the formation in the sand crete located on southern muriwai seaside as demonstrated on my map. On south Muriwai Beach there are fine sand dunes, Bigger sand arete and small sand crete that stretch out across majority of the seashores length. These sand dunes are a reaction to the processes long shore wander and Aeoilian transportation and deposition interacting. As Long shore drift takes place, the develop of sediment is able to dry and become much lighter so the process of Aeolian transportation and deposition can happen. Long coast drift and Aeolian procedures interact simply by allowing the sand granules to be lifted in the air and transported further up the beach, this is the sub process of suspension system. At to the south Muriwai beach data shows that the wind speeds exceed up to 16km/h 42' of the time, that are prime conditions for aeolian...
