Cape Schanck

Coatsal Features Of Cape schanck

Fig. 2 Cape Schanck

Coastal Features Definition:

Fig. 3 Stack

A Stack is part of an arche, when it was still upright. When an arche is collapsed, the two ends that held up the arche is upright, while the bridge of an arche(a sea tunnel), collapses. It can be made out of a series of hard rocks such as basalt or granite. For the Stack, on Fig. 3, it is made out of basalt.

Fig. 4 Headland

A Headland is formed in areas where rocks such as sand and clay are eroded, leaving stronger rocks behind. In order for this to happen, the Headland needs to be surrounded by water on three sides, like in Fig. 4, and usually has vegetation on it, but on this particular Headland, there isn't any vegetation because of the weathering affecting it.

Fig. 5 Wave-cut Platform

A Wave-cut Platform is developed on cliffs made out of softer rocks, that are able to erode quickly, when exposed to ocean waves that contain sand, like the Wave-cut platform in Fig. 5. If a cliff is made out of hard rock such as granite it is much harder to erode, which may not form a Wave-cut platform.

COSTAL PRoCESSES OF cape schanck

Fig. 6 Hydrolic Action

Hydrolic Action is a coastal process when air is trapped in joints and cracks, on a cliff face. When a waves breaks it, the trapped air is compressed which weakens the cliff and erodes it, like in Fig. 6. The cliff is eroded so there must of been Hydrolic Action on this (pebble) beach.

Fig. 7 Attrition

Attrition is the process of where rocks/pebbles are smashed together, by the wave, to the shore to break and make each other smoother, like in Fig. 7. The pebbles in Fig. 8 have been through the process of attrition, several times as the pebbles look smoother than other rocks.

Fig. 8 Abrasion

Abrasion is the process of when bits of rock, and sand, are in waves and grind with the cliff surface, like sandpaper. In Fig. 8, the waves are pushing the rocks onto the cliff's face surface, causing Abrasion.

Unsatisfactory human impacts

Trampling

Fig. 9

Trampling is destroying the vegetation, soil stability and habitats of native birds and animals, on the beach. Fig. 9 shows the effect of Trampling, to a vegetation, soil stability and habitats that results in less vegetation, movement and loss of soil and less habitats for native animals and birds. From this unsatisfactory human impact, it can been seen how much damage Trampling can do to a beach, shown in Fig. 9.

Random Walking Trails

Fig. 10

Random Walking Trails are destroying vegetations and soil statablity. Fig. 10 shows some Random Walking Trails in the middle of vegetation. From this, all the vegetation are being destroyed with the Random Walking Trails invading there space to grow.

Gunnamatta Beach

Coatsal FEatures of gunnamatta BEach

Fig. 12 Gunnamatta Beach

Coastal Features Definition:

Fig. 13 Primary Dune

A Primary Dune is a type of dune. It holds different types of grass and plants such as New Zealand Spinach, Pig Face, Marram Grass and many more. In this particular Primary Dune, Fig. 13, there is Marram Grass. This dune is the nearest to the beach. This dune provides support to the secondary dune by barring protection against flood tides and storms. The barriers are made out of the plant life, holding together. Primary Dune helps to stabilise the beach and reduce coastal ersion. This dune has either a vertical face or 45 degree slop, in Fig. 13, it has a 45 degree slop.

Fig. 14 Beach

A Beach is a narrow strip of land that lies along the edges of an ocean, like in Fig. 14, lake and any other types of bodies of water. For sand to develop on the Beach, it is reached to the shore by the waves pushing tiny proportions of sand onto particular areas of the shore or wind carrying the sand, overtime, creating a Beach.

Fig. 15 Vegetation

A Vegetation is a collection of plant species. It can consist of many many plants such as Marram Grass, pig face, New Zealand Spinach and many more. In the Fig. 15, there is lots of Marram Grass and Spinifex, in this particular Vegetation.

Costal PRocesses of gunnamatta beach

Fig. 16 Long Shore Drift

Long Shore Drift is the direction of movement water, suspense sand and sediment. In Long Shore Drift, there is swash and backwash. Swash is the incoming waves and backwash is the movement of out-going waves. In the diagram, Fig. 16, the Long Shore Drift is going to the left, parallel to the beach. It is used to get out of rips, as well.

Fig. 17 Rips

A Rip is a costal process that is a current. In Fig. 17, the Rip is in the middle of the picture. If something, or someone, were to go in that Rip current, they will be pushed to the sea from the strong force, of the current. If this happens, that object, or perosn, is in a Rip current, which is not safe.

Fig. 18 Weathering

Weathering is a costal process and it is not really good, towards beaches that have vegetation, like in Fig. 18. Weathering can be in may forms like rain or wind. If Weathering was to effect this vegetation, it can ruin and damage it causing the grass and flowers to blow around the beach and potentially destroy the vegetation.

UNSATISFACTORY HUMAN IMPACTs

Trampling

Fig. 19

Trampling is one of the immense problems impacting many environmental, sensitive areas, like the one in Fig. 19. In this particular case, Trampling has effected a primary dune, resulting the sand to move around, reshaping the beach from its original shape, from humans sitting on the primary dune. It also disturbs the sediment layers of the sand and habitats of native animals and birds, living in the vegetation, of the primary dune.

Car Park

Fig. 20

A Car Park, in Fig. 20, is destroying the tertiary dune by replacing all the gum trees, bushes and vegetation with concrete Car Parks. From this impact, native animals and birds habitats are also disturbed.

St. Andrews Beach

Coastal features of st. andrews beach

Fig. 22 St. Andrews

Coastal Features Definition:

Fig. 23 Wave-cut Platforms

A Wave-cut Platform is mainly developed in areas where a cliff is made out of a soft stone that can easily erode when exposed to ocean waves with sand contained in the waves but with a cliff that has hard rock, like granite, it is much harder for a Wave-cut Plaltform to develop. In Fig. 23, there is a cliff, but it isn't tall, with soft rock resulting in a lot of Wave-cut Platforms.

Fig. 24 Vegetation

Vegetation is a group of plant species. It can consist of many species such as New Zealand Spinach, Pig Face and many more. In this particular Vegetation, Fig. 24, there is Marram Grass, Spinifex and Pig Face.

Fig. 25 Beach

A Beach is a narrow strip of land that lies along the edges of an ocean, like in Fig. 25, lake and any other types of bodies of water. For the sand component, on the Beach, it is developed by tides or wind carrying tiny proportions of sand, to random areas on the shore of a Beach, later creating a full Beach. In Fig. 25, this process, for a Beach to be created, has happened many times as this Beach looks fully developed.

COSTAL ProCESSES OF St. Andrews beach

Fig. 26 Long Shore Drift

Long Shore Drift is the movement of the water carrying the suspense sand and sediment. There is two things in Long Shore Drift, one is swash and the other is backwash. Swash is the waves that is coming towards the shore and backwash is the opposite, the waves going back into the sea. In Fig. 26, the Long Shore Drift is parallel to the beach. Long Shore Drift is used to get out of rips, successfully.

Fig. 27 Abrasion

Abrasion is a costal process where bits of rocks or sand are in waves and grind down, into the cliff face surface, like sandpaper. In Fig. 27, the waves are pushing the rocks and sand towards the (tiny) cliffs, creating Abrasion.

Fig. 28 Rips

A Rip is a costal process and a type current. It is a current that carries out, towards the sea, away from the shore. In Fig. 28, the Rip is also going towards the sea, away from the ocean. The black arrows on the side are the currents, but a Rip goes directly into the sea. In an object or person is in a Rip current, they will be dragged away from the shore and are in potential danger.

UNSATISFACTORY HUMAN IMPACTS

Houses

Fig. 29

Houses built on tertiary dunes are destroying vegetaion, habitats of native animals and birds, bushes, trees, plants and the tertiary dune. From Fig. 29, it can be indetifyed that Houses, that are built on tertiary dunes, are destroying nature. Houses, being used can produce pollution, rubbish and hazard to the tertiary dune. The ecological system is being impacted from Houses benn built near it.

Trampling

Fig. 30

Trampling is an immense problem on this and all the other beaches in this report. It destroys the soil stability, the vegetation and the native birds and animals living in this area. Is is mainly creating from human impact. From Fig. 30, it can be identified that Trampling has effected a vegetaion. This has caused disruption in the plant's growth, death of the plants and a decrease in number of particular plant species.

MANAGEMENT STRATEGIES

Fig. 31

There are many problems in Cape Schanck, Gunnamatta Beach and St. Andrews such as trampling, that can be seen in Fig. 31, random walking trails, car parks and houses. The management strategies that can be taken into place to control these problems are by protecting the envoirment (flora and fauna), providing educational information, restricting human movement and regenerating the environment.

Fig. 32

Protecting the environment, flora and fauna, is essential for all three beaches. By protecting the envoriment, we need to be more aware of the beach's surrounding, signs which are on Fig. 32, providing educational information, restricting human movement in specific areas and regenerating the envorinment.

Fig. 33

Providing educational information is needed at Gunnamatta Beach, as the state of the vegetation there is in the worst state. From the sight of Fig. 33, we can see how bad trampling has resulted in. Schools, newspapers, media, debate programms and community meetings are forms of how educational information can be heard to everyone in the world.

Fig. 34

Restricting human movement is essential for St. Andrews as there isn't many fences or barriers, like in Fig. 34. We can restricting human movement by, placing more fences and barriers to block people's paths to areas where they shouldn't go or sensitive areas, placing signs in appropriate locations, guards protecting sensitive areas and constructing artificially beaches to preserve natural beaches, like St. Andrews.

Fig. 35

Regenerating the environment is needed at Cape Schanck as there is hardly any vegetataion, like in Fig. 35. Regenerating the envoriment can be achieved by replanting the vegetation, restoring areas where soil stability is weak, restoring damaged dunes and replanting specific plant species on dunes.
