1. this would be an example of urban sprawl as its a completely new suburb that is spreading outwards. it isn't considered urban consolidation because its not building up on other buildings, compacting space and raising the population in a small area. its completely new and is moving outwards.
2. i think there are many good things and many bad things that could happen as an outcome of this development. in the article it says that it creates job opportunities, it's environmentaly friendly and it will have a strong community spirit. the development as a whole would however impact the environment massivly. the natural habititat in the area would be destroyed in the building process, the environment and the ecosystem would be affected massivly and animals will be driven from their homes. this new development also means that more resources will need to be supplied by sydney, such as roads and electricity.

Urban Planning and Development
1. the term urban sprawl is used to describe a city when it becomes to populated and is forced to spread outwards.
2. the term urban consolidation is used to describe the rising population in cities.
3. a highly urbanised country is a country that has a lot of urban spraw, has a high population density.
4. it is estimated that 92% of australians live in urban areas. australia's urban population is concentrated in major cities, which in 2006 accounted for over 13 million people or 65% of Australia's population.
5. the main factors that have influenced the location's of Australians capital cities are transport advantages, also the flat land that is available and the climate.
6. population density is the population in a particular area divided by the amount of land in the area. population density is related to urban sprawl as it is a solution to the problem. the move from urban sprawl to higher population density in cities is urban consolidation.
7. Australian cities don't have very high population densities. Sydney for example has a population density of 2076 per square kilometre compared to Mumba with a population density of 29650 per square kilometre.
8. there are many advantages that urban consolidation has over urban sprawl. infrastructure like public transport, electricity and water supplies are already built for the developments.
9. urban planners have had to be inovative in their design of apartments and new estates to manage the impacts of population growth in cities.
10. A) Melbourne
B) Population divided by land area
C) Sydney, Melbourne, Adelaide, Woolongong, Perth, Newcastle, Canberra, Brisbane, Gosford
D) 8 out 10 of Australias largest cities have a population density over 1000
11. many of the residents would stronly argue that the development of apartments such as the ones in fig. 9.5 lower the value of their properties. also the constant noise and disruption would be extremely annoying for residents who are trying to live their normal lives.
12. living in a detached housing estate is a lot more private than apartment living as you are on your own property. it also allows you to make the regulations and rules, such as the ownership of pets, etc. having your own property also enables you to design and aesthetically modify your property to the way you like, it allows you to give your home its own character. it is also easier to have a family which many people want. an advantage of living in an apartment however means you are usually closer to civilisation in terms of entertainment, work and other aspects that make up an urban area. sometimes it gives you things like water views over a harbour, landmark, etc.

Urban Renew and Decay
aesthetics - The branch of philosophy that deals with the nature and expression of beauty, as in the fine arts.
this picture expresses various colours, emotions, messages and feelings that all contribute to the overall aesthetical qualities.
safety - The condition of being safe; freedom from danger, risk, or injury.
in this picture the man in the cage is protected by the metal framework from the enormous man eating, great white shark.
slums - A heavily populated urban area characterized by substandard housing and squalor.
this is a picture of a slum located in Mumbai, as you can see it is extremely overpopulated, the houses are very low grade and are made out of thin sheets of metal and finally the good health and cleanlyness of the place is not evident or inviting
decay - To break down into component parts; rot.
decay is evident in this photo as the peice of fruit is rotting.
reconstruction and renewal - is the the rebuilding and renewal of towns and cities that have been demolished as a result of war, natural disasters and other destructive forces.
in this photo the building has been demolished during the war and an attempt to rebuild it is being started.
Transport - To carry from one place to another; convey. transport involves the moving of a particular thing or a group of things from one location to another.
transport examples in this phto are trains, plains, vehicles (bus) and boats. they are all forms of transport.
suburbanization - Of, relating to, or characteristic of a suburb.
in this photo there is an overcrowded suburb which is a characteristic that makes it what it is.
environmental factors - environmental factors are different contributors that affect the environment in different ways.
in this photo an industrial area is producing air polution which is an environmental factor.
Light and Sound - Light and sound are aspects that essentially make up the world we live in. light comes from the sun and enables us to see our surroundings. sound enables us to hear things that are happening. swithout light and sound there would not be a civilisation to live in.
in this photo the police siren is producing blue and red lights and also giving off sound to let everyone in the surrounding area know there is a police car.

7.6 The Tweed River Entrance Sand Bypassing Project
1. it became necessary to extend the tweed river breakwaters due to further sand build-up at the entrance of the heads.
2. The breakwater on the southern side of the tweed river acted to trap sand that would naturally be moved in a northerly direction by longshore-drift. The continual build-up of sand on the southern side of the breakwater eventually caused the river mouth to once again silt up.
3. The dredging of the sand at the mouth of the Tweed River was trucked and moved to the gold coast for beach nourishment. This is an expensive solution and one that would need to occur continually in order to maintain the sand supply to the beaches. The removal of the sand is essential for the ships to be able to get through the tweed river mouth. The natural process that causes sandbars to form is silting.
4. The dredging of the tweed river mouth and associated beach nourishment program was only a short term solution as the silting of sand at the mouth of the tweed river is an ongoing process and this management strategy is just not effective long-term.
5. The TRESBP replaces the natural process known as longshore drift in the construction of breakwaters. This construction breaks the drift of the ocean when it hits the beach as it cannot go past the wall of rock.
6. I believe the TRESBP is one of the most successful projects in Australia for a few reasons. Firstly because the intended aim of the project was to stop silting at the mouth of the Tweed River and to stop the formation of a sand bar. The construction of breakwaters was the best thing that could have been done and did work in stopping the silting – temporarily. Even though it is very costly this project can be used as a learning curve for future projects. It gives developers an idea on what they should do the future, which may be even more beneficial and less costly. I’d say as a whole the TRESBP was very successful.
7. –
8. 1962 – you can see that the Tweed River entrance is extremely vulnerable to the build up of sand known as silting and something needs to be done.
1969 – The construction of the breakwaters has opened the Tweed River heads and caused the beach to shift position. There is more sand on the surrounding beaches as the process of dredging has also taken place.
1994 – The breakwaters haven’t really changed but the amount of sand on the surrounding beaches has increased dramatically. Fairly soon a new solution will need to be put in place as the sand will reach the edge of the breakwater and will once again, begin to form a sandbar.
9. In the topographic map the length of the breakwater is approximately 350 metres in 1994. In 1962 the breakwater was not present.
