Outline the main geographical processes relevant to Coastal Management.


The main geographical processes relevant to Coastal Management are, one, constructing houses around lagoons and swamps, the use of wetlands for landfills and the development of sand dunes, two, in certain part of Australia, some minerals can be mined from beach sands to produce of paints and industrial tools, three, stone breakwaters stretching far out to sea are also constructed around ports and marinas to reduce the impact of waves and tidal fluctuations, four, in large cities generate an enormous amount of contaminated storm water and rainwater run-off which pollutes our waterways and damage fragile coastal ecosystems.

Go back to where you came from reflection

What is your initial reaction to this show?
My reaction of viewing this show shocked m\e in many different ways. Firstly, when this show was shown in the class, i was really annoyed how that Raquel was racist to black people 'I just don't like Africans' and how during the trip she was whining and i found it quite annoying. Secondly, my view towards the migrants changed. At first, i thought they should be sent back to where they came from via boat, plane. However, i myself is an international student and i feel the same way where i used to get discriminated and treated unfairly.
What percentage of immigrants are refugees?
1.5 percent of immigrants are refugees.
Why does such a small number of people make for such a big deal both politically and in the media? (give your opinion)
A small number of people makes such a big deal because of their treatment in other countries and also scrutiny on the treatment of people in Australia.
Why does Australia rank among countries accepting refugees?
Australia ranks 18th among countries accepting refugees.
How much extra support do refugees receive in comparison o the other Australian citizens
Refugees receive the exact same amount of support in comparison to other Australian's
How many Asian nations have signed the UN refugees conventions?
11 Asian Nations have signed the UN Refugees Conventions.
Why is it important to note that Malaysia has not signed the UN Refugee Convention? What does this mean for refugees in Malaysia?
It is important to note that Malaysia has not signed the UN Refugee Convention because of Australia's controversial refugee swap with Malaysia, which has now been cancelled. This means that refugees are subject to very bad treatment and conditions in Malaysia while under refugee status.

What is the deal between Australia and Malaysia? (What are the numbers of people being 'swapped'?)
Australia and Malaysia had asylum trade system which Australia will send 800 asylum seekers in return for 4000 genuine refuges whose cause have been verified by the UN Refugee Agency.
What rights will they have in Malaysia which will allow them to support themselves?
Allowed to work, education and medical expenses for all ages
How does Malaysia normally treat illegal immigrants?
They round them up and throw them into detention centers. Some
Are children being sent to Malaysia?
Yes, but they will get all the support of education and medical assistance
What is going to happen to the processing of the 500+ people currently in Australia who have arrived from the 7th of May?
They will have their claims processed in Australia
What do refugee advocates worry about for the 800 asylum seekers?
They worry that the government can't guarantee the human rights safeguards for the asylum seekers and that the asylum seekers may come to harm. For example the asylum seekers may be caned. They also bought up the occasion when an Australian citizen with their passport was taken to a detention centre saying that if the government can;t protect one of their own citizens, how can they protect the asylum seekers?
What is the goal of this 'swap' program?
The purpose of this 'swap' was to stop the boats that are bringing in the illegal immigrants. To decrease the number of deaths that occur when these smuggling ships crash or ans accident happens
Do you think that it will work? Why/why not?
I think it will work because people will still get an oppurtunity at a new life in a more stable country but they won't be coming to Australia anymore because they know they'll just be sent to Malaysia.

What is an asylum seeker?
An asylum seeker is a person who has fled their own country and applies to the government of another country for protection as a refugee.
What reasons would they leave their country and come to Australia?
The reason why asylum seeker's would leave their country and come to Australia is because Australia allows any race, religion, nationality, membership of a particular social group, political opinion because they caused them to flee from their country.
What reasons will allow them to be approved for asylum?
Persecution due to their beliefs, race and nationality, and opinions.
From what countries are most asylum seekers coming?
Iraq and Burma.
What title does Kevin Rudd have in the Australian Government? Explain what this role entails
Foreign Affairs Minister, the highest on the rank.
What is Kevin Rudd concerns?
Kevin Rudd's concerns are that he accused North Korean's nuclear weapons and missile programs are direct threat to Australia, the US, South Korea and Japan are blamed for provoking the current dangerous instability on the Korean Peninsula.
What forum was he at to express his concerns?
ASEAN Regional Forum
What actions have North Korea performed recently which have Rudd alarmed and the region lacking stability?
North Korea has been working for about a decade on its Tapodong-2 long range missile, with a reported design range of 15,000 km, torpedoes sunk Korean naval ship and civilians on the island. 
What is a 'direct threat' to Australia according to Rudd?
The 'direct threat to Australia according to Rudd is the development of the long range missiles that propose danger to the security of our nation, and Rudd would take leaderships and be participating on UN. And they can make lots of allies which is good for strong economy and technology.
What do you think that Rudd is trying to accomplish diplomatically by calling out his North Korean counterpart publicy? How does this relate to Australia's relationship and role in the region?
However a fired-up Mr Rudd said Mr Pak and his colleagues needed to re-engage with reality if their renewed discussions with the outside world were to bear any fruit. This relates to the relationship of Australia and the countries of the region because in the eyes of other nations Australia will be seen as a leader and many countries will have a positive perception of what Australia is doing, promoting the relationship with it's neighbors.
How does this relate to Australia's relationship to major allies?
This relates to Australia's relationships to major allies because in doing this Australia will demonstrates its loyalty and promotes its status with other allies.

Summarizing the article 'We're not helping really' and Opinions.

Dot Points (article)
  • By 2015 we will be spending $8 billion a year on helping people overseas.
  • Kevin Rudd announced a review of Australia's overseas aid program by an impressive panel of experts. 
  • Helping people in need is a good thing to do, and there are always more people who need help but spending money in ways that make no difference doesn't help anyone, and there is no virtue in aid that makes donors feel good but doesn't help the needy.
  • Most obviously, emergency relief after disasters such as Indonesia's tsunami can save thousands. But this accounts for only 7 per cent of today's program.
  • First, poverty is being overcome. In 1981, 54 per cent of the world's people lived in extreme poverty. By 2005 this had fallen to 25 per cent. In 2015 it will be less than 15 per cent, according to the World Bank
  • Many of the world's most populous nations, left behind two centuries ago by the industrial revolution, are finally catching up.
  • In China, economic growth has lifted half a billion people out of poverty since 1990
  • Now, as we watch some of the word's poorest countries start to grow of their own accord, we can see more clearly that aid in any form (capital, technology, roads, schools, armies of technical advisers) does not make much differences.
Opinion (my perspective)
I reckon i agree with the author of this article because we are just spending money and there is no proof that aiding some countries will come out positively. Aiding program that Kevin Rudd started since 2005 (?) may end up wasting money. "But spending money in ways that makes no difference doesn't help anyone, and there is no virtue in aid that makes donors feel good but doesn't help the needy." this explains that Kevin Rudd was just wasting 8 billion dollars on aiding and never see the outcome. However, in the other hand, some aids help for example, Indonesia's Tsunami can save thousands homeless people which was very effective. But in the end, Indonesia could have built new school's with their money but Australia is just spending money on unnecessary things.

Why do you think Australia is giving more Aid? What would be the benefits of such a policy? What would be the negatives?
Because due to that Australia got into UN security council, now Australia is grabbing attention and therefore, we can impress America and we would look good if we keep aiding. Aiding other countries would benefit us by looking towards the future. We can benefit not economically but where we can have close relationship from other countries and they will owe so much in trading, military. However, Australia could have helped poverty's instead of helping other countries first because in Australia we are experiencing poverty, homeless, unemployment a lot and we could help them first. One more thing that is negative that aiding countries is that Australia may be low on money.

A city in five images

FINLAND
Helsinki is the largest city in Finland. It's the region of Uusimaa, located in southern Finland, on the shore of the Gulf of Finland, an arm of Baltic Sea. The population of the city of Helsinki is 588,941 (31, Jan 2011).making it by far the most municipality in Finland.

Helsinki is spread across a number of bays and peninsulas and over a number of islands. Population density in certain parts of Helsinki's inner city area is very high, reaching 16,494 inhabitants in kilometres in the district of Kallio.

I picked this image because this is a view seen from spot satellite. And also, you can see numerous islands, bays, and peninsulas in this image and i believe this is important to start with.







Helsinki Cathedral is an Evangelical Lutheran Cathedral of the Diocese of Helsinki, located in the exact centre of Helsinki. A distinct landmark in the scenery of central Helsinki, with a tall green dome surrounded by four smaller domes, the church was built in 1830-52, in neoclassical style.

The reason why i chose this image was because this Cathedral was built exactly in the centre of Helsinki, and it became one of the landmark's in Finland.



Finlandia Hall is a concert hall with a congress wing in Helsinki. The building was designed by Alvar Aalto. This work began in 1967 and completed in 1971. The main features of the building's exterior are the great horizontal mass of the building proper and the towering auditorium that rises above it. The main external wall material is Carrara marble and with copper roofs, which have acquired a green pantina, and teak window frames.

Another reason why i chose this picture was because that this building by Alvar Aalto, who built so many other buildings such as Auditorium of University of Technology.

Aleksanterinkatu is a street in the centre of Helsinki. The street begins near the Presidential Palace and continues to meet with Mannerheimintie, the longest street in Helsinki. It runs past several famous buildings, such as Ritarihuone (the seat of Finnish nobility), the Helsini Cathedral.

This is just a street photo but still, this street is famous for the length, where it was linked with and shops around so many tourist visit this place.







Helsinki Swimming Stadium is a popular refreshment place for citizens. It is open from the beginning of May to the end of September. It is a popular place, and in summertime it is visited by about 5000 swimmers every day. The Stadium has three pools: a 50 metre exercise swimming pool, a jumping pool and a children's pool, and a small, shallow, round wading pool for small children a litter further away. The jumping pool has two 1 metre and two 3 metre high springboards, and a 1 metre plateau in front of the jumping tower. The area also has a water slide, a gym, a basketball field, a volleyball field, a table tennis table and a café.

Urban Sprawl or Consolidation : Jordan Springs

1.  Urban sprawl, because in Jordan's Springs, there were nothing and everything is brand new and away from cities. Most homes were made of low density, and it promotes less pollution by using more of buses, and cars.

2. I think, this new development is positive for the people who doesn't have any job and poor. The people who doesn't have job, will find this new development a chance of them getting a new job.  '5300 jobs would be created.' For Sydney, i think they would think this new development would be negative because they have to share and lose resources, electric powers, and water supply to this new development. Also Sydney might think that they would lose some of their population to Penrith.

9.1 Australia- the urban nation

1. What is meant by the term 'urban sprawl'
urban sprawl is when as a city's population increases, the easy solution is to simply add more suburbs to the edge of the city to accommodate people.


2. What is meant by the term 'urban consolidation'?
Urban consolidation refers to a diverse set of planning set of policies intended to make better use of existing urban infrastructure by encouraging development within existing urbanised areas.

3. What is meant by a highly urbanised country?
Highly urbanised country is where most of the world's population lives in a certain country such as China, America.

4.List three statistics that suggest Australia is a highly urbanised country.
Sydney, NSW - 3502000 total population in 2001
Melbourne, VIC - 3162000 total population in 2001
Brisbane, QLD - 1508000 total population in 2001
and more.

5. What factors have influenced the location of Australia's capital cities?
because Melbourne and Sydney had the most population in Australia, they were having a debate which city should be the capital of Australia. However, they finally decided that they couldn't choose between Melbourne and Sydney therefore they measured the exact middle between two cities and constructed Canberra.

6. What is population density and how is it related to urban sprawl?
As i said in question 4, Sydney has 3502000 total population measured in 2001 and this record is related to the urban sprawl due to the fact that States such as NSW, and VIC has good, balanced weather and is comfortable to the people to live.

7. How do Australian cities compare to other cities in the world in terms of their population density?
Mumbai has 14350000 total population and the land area is really small, and Sydney has only 3502000 total population. Compared to cities such as Mumbai, Sydney's population is nothing.

8. Describe the Advantage, in terms of the provision of infrastructure, urban consolidation has over urban sprawl.
Because Sydney doesn't have that many people (3502000 total population) and the land area is 1687km2 it is wise and taking the advantage of the use of land.

9. How have urban planners responded to the issue of urban sprawl in Australia?
Urban planners have had to be innovative in their design of apartments and new estates to manage the impacts of population growth in cities. One of the changing aspects of Australian cities in the movement towards high population densities within the city. In a process known as urban consolidation, land within the existing city's boundary is developed with high-rise apartment complexes  townhouses and villa developments.

10. Refer to 9.2:
a) Which Australian city covers the greatest land are?
Melbourne (2080 km2)


b) Describe how population density is calculated.
Population density is calculated by dividing the population of the country to the square density so you divide both of them and you get the population density.


c) Rank Australia's cities in terms of their population density.
1. Sydney - 2076
2.Melbourne - 1520
3.Adelaide - 1374
4.Wollongong - 1251
5.Perth -  1221
6.Gold Coast - 1102


d) What proportion of Australia's 10 largest cities has a population density greater than 1000 people per square kilometres?
Sydney, Melbourne, Brisbane, Perth, Adelaide, Gold Coast, Canberra, New Castle, Gosford, Wollongong

11. Refer to 9.5 and discuss the opinions the residents in the detached housing in the foreground might have to the apartment buildings being constructed. What impact will the construction have on their community?
The construction will have a large impact as it will greatly overshadow the smaller houses around the large apartment developments. They will cause about 75% increase in the number of people living in that area. It will also cause shadowing over the smaller houses as the apartment buildings are large and bulky.

12. Discuss the advantages and disadvantages of living in a detached style housing estate compared to apartment living.
Well, i myself live in apartment buildings and advantages of living in a detached style house's have more space and it is good for kids environment. I prefer to live in a detached style houses because we have our own property and privacy is needed.

7.8 Dune Revegetation at Stuarts Points

1. Name and Locate the coastal dune management area discussed in this unit.
Stuarts Point is a small coastal village located on the mid-north coast of NSW. The dune area is 5 kilometres long with its width varying from between 200 to 400 metres.


2. Using the material in the unit, construct a timeline that highlights the changes in the Stuarts Point sand dune ecosystem.
1893: Castle grazing destroys fragile vegetation
1893: Ocean breaches sand dune on 3 occasions
1965 (May) : Planting advice given to progress association
1965 (August) : Cattle grazing destroys vegetation again
1970: Stabilisation of sand dune through revegetation
1972: Controlling access to the dunes was implemented

3. Describe the role of the local community in managing the sand dune area.
Local community is putting their hand in together to complete the goal of re-establish the sand dunes. Local people volunteering to plant and taking care of revegetation.

4.Why is the sand dune are important to the people of Stuarts Point
Because it provides an important sand dune barrier that separates the beach from the Macleay River.

5.Using 7.35 describe the natural vegetation succession on sand dunes
The natural coastal dune vegetation succession consists of primary, secondary and tertiary species of plants, each adapted to the environmental conditions unique to coastal dunes

6. Explain why vegetation is so important in stabilising sand dunes.
Vegetation is so important in stabilising sand dunes because the plant roots dig into the sand and actually fixes the sand. It allows the sand to be locked in place by the plants and will not blow away.

7. What impact did cattle grazing have on the sand dune area?
They ate the vegetation so the dunes started to wear away

8. Describe the changes to the sand dune area that would have occurred after cattle grazing,. Identify the geographical processes that would have been altered as a result of the removal of vegetation from the dunes.
After the cattle grazing most of the dune would be bare sand, the geographical process altered would be the plants protecting the dunes from being blown away.

9. Identify the groups involved int he rehabilitation program
The Department of Lands, the Department of Public Works, the Macleay Shire Council, and the Soil conservation Service of New South Wales

10. Outline the stages involved in the management program undertaken to re-establish the coastal vegetation.
The first stage involved using a tractor to form a small foredune approximately 1.8 metres high. On top of this a dune-forming fence was constructed to help trap the wind-blown sand and establish the foredune. This dune was essential to protect the hind dunes and allow vegetation to grow. The foredune was then stabilised with coastal spinfex and marram grass. The next stage involved planting trees along the riverbank to stabilise the western margin of the area. After this was completed it was a matter of planting native seedings in the area between the foredune and the river bank. Initially, fast growing secondary species like coastal wattle and Casuarina equisetifolia were planted. Once they were established, coastal tertiary species like banksia, melaleuca and leptospermum were planted.


12. Use maps to explain the geographical process that would have caused the river mouth to silt up.
The Longshore Drift

13. Evaluate the success of the revegetation program in the following areas:
a) Stabilising the sand dunes.
Sand movement within the dunes is now negligible. A large foredune 3-4 metres high is present and covered with vegetation. This acts to protect the hind dune vegetation from salt-laden winds and erosion from waves. The hind dunes still run east-west as no mechanical work was conducted to repair the wind damage on the hind dunes when the area was revegetated. A coastal dune ecosystem has been reestablished on the dunes.


b) Protecting the Macleay River ecosystem.
The Macleay river ecosystem is now protected as a result of this


c) Benefiting groups from the local community.
The community fishing and tourism industry of the area has been restored to its full strength.

14.
Firstly, vegetation on sand dunes protects the dune from being blown away by winds. The vegetation succession that protects the dunes starts with the bare beach, then grasses and creepers on the incipient dune, then shrubs and short-lived trees on the fore dune and finally long-lived trees on the hind dune. Longshore drift as well as strong winds and heavy rain can cause a sand dune to move inland. Close off the dunes and re-plant vegetation and only re-open dunes once vegetation has grown back.

Year 10 Monday 28/2: Summarising the TRESB Project

1. The problem which lead to the TRESB project
 The continual build-up of sand on the southern side of the breakwater eventually caused the river mouth to once again silt up. It became apparent that continually extending the breakwaters was not the solution to providing a safe entrance to the Tweed River. In an effort to create a safe river entrance and solve the problem of the breaches immediately north of the Tweed being deprived of the natural supply of the sand, the accumulating sand at the river mouth was periodically dredged and trucked to the Gold Coast where it was used for beach nourishment.
2. The solution of the Problem
The solution of the problem is by doing which would need to occur continually in order to maintain the sand supply to the beaches and the safety of the river entrance for boats. A more efficient long-term solution was required. 
3. The result of the project. What areas were effected and how? Do you think that it was a success? 
(TRESBP) The Tweed River Entrance Sand Bypassing Project is a very smart thing that Australia has done. This is because the planning, construction and effects of the TRESBP was so well thought out and that so much research was done into the project such as refering to coastal managers, authorities, geographers, etc. And the solution is simple and effective with the idea that it measures which beach needs the sand the most and places the pumped sand there.

7.6 The Tweed River Entrance Sand Bypassing Project

1. because during 1950's shipping was harder due to the fact of sandbars that were forming across the river mouth.


2. The continual build-up of sand on the southern side of the breakwater eventually caused the river mouth to once again silt up. It became apparent that continually extending the breakwaters was not the solution to providing a safe entrance to the Tweed River. In an effort to create a safe river entrance and solve the problem of the breaches immediately north of the Tweed being deprived of the natural supply of the sand, the accumulating sand at the river mouth was periodically dredged and trucked to the Gold Coast where it was used for beach nourishment.


3. During the 1950s the entrance to the Tweed River, which is at the southern end of the Gold Coast, became a hazard to shipping because of sandbars that were forming across the river mouth.

4. This was an expensive solution and one which would need to occur continually in order to maintain the sand supply to the beaches and the safety of the river entrance for boats. A more efficient long-term solution was required.

5. The Tweed River Entrance Sand Bypassing Project (TRESBP) provides an example of how people can implement coastal management schemes that recreate the natural processes operating along the coast. The project also involved the cooperation of state and local governments in responding to the community's concerns and opinions.

6.  (TRESBP) The Tweed River Entrance Sand Bypassing Project is a very smart thing that Australia has done. This is because the planning, construction and effects of the TRESBP was so well thought out and that so much research was done into the project such as refering to coastal managers, authorities, geographers, etc. And the solution is simple and effective with the idea that it measures which beach needs the sand the most and places the pumped sand there.


7. 


8. The changes occurred at the mouth of the Tweed River since 1962 have been dramatic. The most prominent thing that has changed is the beach becoming larger with larger amounts of sand being placed on the beach. Over time the sand has not been transported away from the beach into the river but instead now is all being retained within the beach being held by the breakwater.


9. The breakwater length in 1962 would of been about 40 meters long. In 1994 it has been extended to about the length of 250 meters.

Homework


Cribber

Cribber wave only just start with to break safety at 6 to 8 ft. It is located in the north headland at New quay Cornwall's Fistral beach. It only creates the big waves few times a year and after the break, it needs to hold the power to create 25+ ft waves but as soon as it reaches near its shore, it looses the power.
