1. Is this an example of urban consolidation or urban sprawl? Why?
It is an example of urban sprawl, as it is a new development not extending an existing infrastructure. It is made 7km out of Penrith so its out of the way and made on a mass land. It holds 2500 homes.
2. Do you think that this development is positive or negative for the surrounding community? For Sydney? For Australia?
I believe it can be positive as it creates job opportunities for trade workers, however it also pull people out of the surrounding suburbs, therefore could also have a negative impact.

Urban Renew and Decay
- Aesthetics
- Definition - the branch of philosophy dealing with beauty and taste, "is it aesthetically pleasing" how something looks.
This image is Aesthetically pleasing, as it is a building that looks good.
Safety
Definition - the state of being certain that adverse effects will not be caused by some agent under defined conditions
This image shows safety, as the high walls around this town give it a sense of safety to the people in the town.
Slums
Definition - a run-down area of a city characterized by substandard housing and squalor and lacking in tenure security.
This image shows the state of what some slums are like and how run down the areas are.

Urban Decay
Urban Decay
Definition - Urban decay is a process by which a city, or a part of a city, falls into a state of disrepair and neglect.
This image is an example of urban decay, it shows and building that is basically falling apart and has been neglected.
Reconstruction and renewal
Definition - Areas devastated by war or invasion challenge urban planners. Resources are scarce. The existing population has needs.
This image shows a new building plan or a reconstructed city.
Transport
Definition - Transport within urbanized areas presents unique problems. The density of an urban environment increases traffic, which can harm businesses and increase pollution unless properly managed.
This image shows the a station, this is an option of transport over cars.
Suburbanization
Definition - In some countries, declining satisfaction with the urban environment is held to blame for continuing migration to smaller towns and rural areas.
This image shows that although an important factor, there is a complex relationship between urban densities and
car use
Environmental Factors
Definition - Environmental protection and conservation are of utmost importance to many planning systems across the world.
This image shows a tightly compacted suburb with little to no trees.
Light and Sound
Definition - The urban canyon effect is a colloquial, non-scientific term referring to street space bordered by very high buildings.
This image shows the effect of light.

Coastal Management - The Tweed River Entrance Sand Bypassing Project
Questions 1 - 9 page 167
Q1. Why did it become necessary to extend the Tweed River breakwaters?
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 silt up and cause a blockage.
Q2. What impact would the construction of the breakwaters have had on the replenishment of sand to the Gold Coast beaches after severe storm erosion?
The Tweed River became unsafe for shipping because of sand bars building up in the River mouth making it shallow so the ships will run aground in the mouth so they had to stop shipping in the Tweed River.
Q4. Why was the dredging of the Tweed River and the associated beach nourishment program only a short-term solution to coastal management of the area?
It was only a short term coastal management as the barriers were not big enough so the sand built up over time and therefore had to rebuild them again.
Q5. Describe the way the TRESBP replaces the natural process of longshore drift.
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.

Q2. What impact would the construction of the breakwaters have had on the replenishment of sand to the Gold Coast beaches after severe storm erosion?
The construction of breakwaters will cause the beaches on the Gold coast to loose sand due to longshore drift and the beach will be unable to naturally get their sand back, as it will but getting stuck at the river entrance.
Q 3. Why did the Tweed River become unsafe to shipping? Explain the natural process that caused sandbars to form over the mouth of the Tweed River.The Tweed River became unsafe for shipping because of sand bars building up in the River mouth making it shallow so the ships will run aground in the mouth so they had to stop shipping in the Tweed River.

Q6. Write a paragraph that explains your opinion of the TRESBP. Why do you think the project is regarded as one of the most successful coastal management schemes in Australia?
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. It gives developers an idea on what they should do the future, which may be even more beneficial and less costly.
Q7. Draw an annotated map to explain the operation of the TRESBP.
In the Book on page 167
Q8. Look at the aerial photographs in 7.28. Describe the changes that have occurred to the mouth of the Tweed River since 1962.
1962 – In this image it makes it very clear why the Tweed River mouth became a problem for silting up with sand, as the mouth is so open and unprotected from any thing it becomes very vulnerable to clogging up.
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. however the river mouth looks alot cleaner and deeper therefore looks like it is working.
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.
Q9. Using the topographic map in 7.25 on page 164, estimate the length of the breakwater along the Tweed River entrance in 1962 and in 1994.
In the topographic map the length of the breakwater is approximately 350 metres in 1994.

Summarising the TRESB Project
The problem which lead to the TRESB Project.
The problem that lead to the TRESB project is that the shipping path in which the boats would go in and out of, was continually filling up with sand a other stuff that was moving northwards from the beaches.
The solution to the problem.
In solution to this problem, barriers were put into place to allow the sand to build up near the enterance. This sand is then moved up the coast where it will no longer be affecting the river.
The result of the project. What areas were effected and how? Do you think that it was a success?
As a result of the project, beaches on the gold coast were affected because of the sand was being caught up in the rivers and the sand from the beaches was slowly going away.
However this project was a success because of the way that it solved the problem of the blockage of the Tweed River.
