There are several natural features that create the Muriwai Coastal Geographic Evnironment. One natural feature is the beach, and the processes performed to create this natural feature are wave erosion, wave transportation, wave deposition, long shore drift, prevailing south westerly winds, the aeolian process, high energy waves and also swash and backwash.
The waves erode the black rock off the edges of Mount Taranaki (Mount Egmont) and is then carried northwards through wave transportation and long shore drift with the help of the prevailing south westerly winds therefore known as the aeolian process. The black sand is carried through the high energy waves along the west coast depositing sand onshore as it goes past the beaches. The energy of the waves are so strong that the sand being dropped off is left in large amounts on the beach front. The sedimant is deposited through the swash and backwash process where the waves approach the shore in an oblique angle and then moves back towards the sea perpendicular, therefore creating a zig-zag pattern along the beach. This is one of the natural features created at the Muriwai Coastal Geographic Environment, and the several processes that are performed to make this particular natural feature.

At Muriwai there are several natural features that make up the MCGE.

The sea arch is a natural feature that is found in the MCGE. It was formed from the starting of a sea cave and is the joining of the cave to form a sea arch.

This happens when the caves merge together as the waves hit against it to make the material erode right through to the other side and thats how the sea arch was formed.

The Sea Arch is loctaed on Maori Bay and was created by the wave erosion, wave transportation, wave deposition, long shore drift, prevailing south westerly winds, the aeolian process, high energy waves and also swash and backwash where the waves splashes into each other making the rocks weaker, thus erode quickly forming the Sea Arch

The arch looks exactly like a cave, which goes right through to the water and it's approximately 4 to 5 metres high.

The waves erode the black off the eges of MT Taranaki and is then caried northward through wave transportation and from there the Long shore drift with the help of the preevailing south westerly wind so therefore known as the Aoelian process.

One of the natural features that can be found at muriwai beach is that of the sand dunes which are made when the sediment or sand on the beach become dry and the wind (aeolian process) carries it to the sand dunes and also the backshore. This makes the sand dunes bigger it can wind can also make them smaller. They increase and decrease depending on which way the wind blows.......
