Coastal Management Report: Collaroy Beach Essay

However this idea also seems to be out of reach, as after the successful “Line in the Sand” community protest in November 2002, the council voted 4 months later not to proceed with the sea wall option.A beach in which the sea waves have gradually restored the sand to the incipient dune from the sandbar, as well a stable fore-dune are the tell-tell signs of a post-stormprofile.Key Interest GroupsThe key interest groups involved with the issue of the erosion of Collaroy include groups such as Sydney Coastal Councils Groups, which have criticize the non-actions of the Warringah Council to set up a plan in the long term, instead focusing on short term relief such as sand replenishment, which SSCG deems as unsustainable in the long run.When p...

Vegetation in the Initiation and Morphological Development of Coastal Dune Systems

The interplay between sand availability, sand movement, vegetation and water table level is crucial in determining dune morphology and evolution.Fore dunes are also often known as yellow dunes, on account of the amount of bare sand yet to be colonised.The blowouts that induce this mode of erosion may in turn initiate further degradation within landward dunes as drifting sand buries and kills vegetation in its path.Dunes are produced by wind transport of sand, supplied by marine processes, but the nature of the wind activity is critical in determining dune morphology and distribution.As more sand accumulates, the embryo dunes join to form fore dunes which can reach a height of 5m.

Muriwai coastal process

Marram grass is able to grow through the continual coverings of sand and therefore continues to intercept new sand that accumulates.LSD has provided the sand to form dunes.In conclusion LSD, saltation, interception by vegetation and accumulation are all processes that interact to form sand dunes at Muriwai beach.However when all processes are in occurrence the four will work together continue to formation of sand dunes at Muriwai Beach.The combination of both wind speed and direction enables sand to move up Muriwai beach towards the sand dunes.

The Atmosphere Hydrosphere Lithosphere

A parabolic dune is a sand dune that is in the shape of a U or V. these dunes can be very long and they form parallel to the coast.Precipitation affects the nature of vegetation that grows on the sand dunes, which ultimately affects the strength of the dune system.If a coastal area is very moist with constant rainfall then it will have considerable vegetation to bind the sand together, however if it has a dry climate there will be a lack of vegetation thus meaning that there will be a less diverse range of vegetation, sand will not be bonded strongly by plant roots resulting in an unstable ecosystem that can suffer from change easily.In areas of warmer weather sand will dry faster, thus allowing the wind, through Aeolian transport to dep...

The Ecosystems At Risk Environmental Sciences Essay

The sand is dried from the wind and sunlight, and is then able to be transferred to the dunes.Dune reconstruction usually occurs on dunes that lack in sand.For example in Lake Huron, Ontario, Canada research has found that the number of vehicles having access to the dunes has caused the deeper sand to become compact and surface sand to loosen.The amount of sand removed is dependent on the size of sand, velocity of the wind and nature of vegetation cover.If the dune is somewhat degraded then pioneer dune grasses, like sand spinifex, are brought in to stabilise the dune, then introduced are the secondary vegetation like she oaks and finally tertiary species like coastal trees.

Tourists are in Conflict with the Sand Dune Ecosystem at Oxwich Bay Nature Reserve

* Well-developed dunes typically have a sinusoidal profile with the primary dune at the seaward edge of the beach and possible secondary dunes located farther inland.Sand dunes are formed by winds blowing sand landward from the dry part of the beach.* Vegetation on the dunes traps windblown sand on their downwind side and promotes dune growth and stability.“Oxwich Burrows” or the sand dunes at Oxwich stretch the whole length of the Bay.* Wave erosion of sand dunes transports sand offshore and creates a steep scarp at the base of the dune.

The Sand Dune Ecosystem

The sea spray makes the conditions very salty meaning high salinity levels so the conditions in the small pile of sand are very hostile.There are four different dunes in a sand dune ecosystem that relate to the seres.With these better conditions the number and range of plants increases covering, in places, the entire sand surface.Rapid deposition of sand, lack of water and lack of nutrients in the soil all attribute to the plants that can survive.Soil particle size has a huge impact due to the fact that the sand particles are quite large so water drains quickly meaning that it will be very dry.

The Four Different Spheres

The two ecosystems at risk, coral reefs and sand dunes, are both highly specialised, and for this reason there have been many traditional and contemporary management strategies used to sustain them, and keep them as risk free as possible.The weight of vehicles and other means of transport compact the sand, resulting in the sand having less oxygen and therefore less plant growth.The chain and board paths help the coastal dunes through reducing trampling by humans, as well as the timber slats being an obstacle to wind erosion to the exposed sand.The type of local vegetation and amount of vegetation on the sand dunes also impacts aeolian transport, as the vegetation becomes a barrier against the wind for the sand, and the greater the vegeta...

An investigation in the different species of plant life through bare sand and grassland and what factors effects the growth of them

The marram grass stabilises the sand dunes due to the extensive underground network of rhizomes that binds sand to stabilises the dunes.Towards the start of the embryo dune where there are no plants present is due to that this is the place where the high tide comes up to and this makes the salt content of the sand very high even the marram grass is not able to grow here.On the way I will have to investigate the area the different species thrive in to be able to conclude what factors affect the growth of them and prove that marram grass only grows on certain parts of the sand dunes and if it has a factor of keeping the embryo dune together.From doing past work in biology I have learned that marram grass is a xerophyte so this plant is bas...

Wind is an Important Agent of Deposition and Transportation

Seif dunes are long sand ridges of irregular shape and variable length.The sand grains on the windward side move up the back of the dune and fall over the crest onto the leeward side, which is kept steep by wind, eddies.Seifs seem to be developed where there are dominant winds from a different direction from the prevailing ones, which have accumulated the sand.Saltation, or the hopping of grains of sand is caused by turbulent air lifting the sand almost vertically and then moving it forwards.The most detailed studies of wind action were made by Bagnold (who concluded that wind itself has no direct erosive action, and that blown sand can seldom abrade rocks which are more than 18 inches above the ground and that sand, as opposed to dust, ...

Coastal Management is More Effective at Fairlight than at Camber

Unlike at Fairlight here I found a lot of vegetation growing through the sand on the dunes.The beach at Pett level have a number of wooden groynes going along the beach to reduce longshore drift and to trap the shingle and sand from going down the coast, the beach is often renourished with the pebbles, shingle and sand which has got to the other end of the beach.They only had rotten wooden fences to keep the sand from blowing away and to be quite honest it wasn’t working.Here you will find long stretches of sand dunes and at low tide flat sandy beaches.On a windy day like it was when I went all the sand was blowing on the top of the dunes and going across the beach and ending up somewhere else.

Coastal management involves developing strategies Essay

Recreational activities like four-wheel driving places pressure on the coastal environment if it is not carefully managed, large dune areas and beaches where vehicles are given access can be highly susceptible to erosion.Fences are a useful management technique used to ensure adequate access to beach for people while protecting the vegetation that stabilizes the sand dunes.Signage is very important when it come to beaches as it tells people what you can and cannot do on the beach basically tells you what you are allowed to do on any beach but the signage stops bad things from happening to the beaches and what you are meant to do on the beach.People should not have to go and tidy up after other people who dump their rubbish on the beach.T...

Coastal Management Northern Beaches Sydney Collaroy

As the sand grains get trapped they start to accumulate, starting dune formation.Winds can affect the formation of the beach as the wind can form sand dunes by pushing the sand back inland along the beach.The first being minor sand nourishment, which involved moving sand from one part of the ecosystem to another.The next strategy was sand nourishment.Gradually this action causes the dune to “migrate” inland; as it does so it accumulates more and more sand.

Coastal Landforms and Features Related to the Rock Type of the Area

With the graph just as it is if we added results for all we know the trend could be lost and this would show that there was no relationship after all.Otherwise this graph clearly shows that as a rock gets softer the cliff it is made out of becomes smaller.We could have used a tape measure but this would have difficult as someone would have had to stand at the top of the dune and it would have crumbled under foot as it is simply blown sand.It was also difficult to plant the measuring pole at the base of the dune and get the exact height as can be noticed in P3.[IMAGE] This shows a definite downward trend but because there are so few results it doesn't really tell us much.

Death Valley National Park Essay

The sand is transported by the wind, and the dunes are mobile.However, a plausible hypothesis remains that some rainy nights make the sand slippery and strong winds then move the rocks.The greatest depth of sand there is 40-43 meters but this remains little compared to other nearby dunes where you can find up to 183-213 meters of sand.Between the dunes, there are creosotier and prosopis (Prosopis juliflora) bushes that grow on the sand and dried mud that make up the soil of this part of the valley (under the more recent dunes ).The Mesquite Sand Dunes (“prosopis dunes)” are located north of the valley.

How the Carboniferous, Variscan Orogeny and Quaternary affect the geology of the Gower Peninsula

The trip to Three Cliffs Bay was also helpful, it showed us what modern sedimentary environments are in the United Kingdom, and more specifically South Wales.These included beaches, point bars, flood plains, sand dunes, storm beaches and salt marshes.At the storm beach we took clast measurements to show the direction of current when the rocks were deposited.All the rock types present at Caswell Bay are carboniferous, and were formed in the same conditions as we currently have in the Bahamas, very warm, tropical, marine, shallow environment.There would have been a lot of animal and plant life at the time, this is shown in the High Tor Limestone with it being very fossiliferous.

Marck Essay

These embryonic dunes are submerged during high tides but the balance remains positive with a fattening of dunes generating a gradual rise.The site was then abandoned probably in connection with a period of increasing humidity but remained emerged with enough vegetation abundant to be able to fix the fine sand propelled by the wind.At this point, the wind will allow the accumulation towards the top of the sand beach which will be trapped by a dense reinforcement of rhizomes and aerial stems of farctus Elymus (sand quackgrass or quackgrass spicy, particularly colonizing species).The westerly sea currents leaving the Pas-de-Calais play a major role with the formation of open sea sandbanks (Calais ridens, harbor ridens) constituting a large...

A Comparison of the Writing Styles of Mary Austin and Willia Cather Essay

Like Austin, Cather uses the landscape to springboard themes and motifs throughout the book, often the scenery being an outward expression of the thoughts and feelings of the characters.The style of both authors have similarities but have distinct differences.The landscape of the story is no doubt a desert; sand dunes, small shrubs, will grass, blistering heat, scavengers and very little the way that the dunes are blown up on themselves that eventually form a shield that protect the grasses and shrubs that grow behind the dunes.For example, the rugged, untamed, potentially dangerous landscape foreshadows the imminent suicide of his friend’s father.

The Coastal Systems

Soft engineering is where the defense chosen works with the environment such as afforestation to stabilize sand dunes or beach replenishment.The management techniques that they use include; nourishment of beaches by building and maintaining groynes; planting grasses and trees to increase the stability of the dunes; fencing off dunes to decrease human interference and erosion, and finally placing sleeper dykes below the dunes to help keep them bedded.This is the primary source used by the government, where in 1990 they decided to have a plan where they controlled erosion completely, and this would happen mainly through replenishment of the sand dunes.The many examples show that coasts are extremely hard to control as they are too costly i...
