The site which they are planning to build is identified as site x and is located on the east of Tidmarsh. It is 5 3/4 miles from West of Reading and 40 miles West of London. The grid reference for the site X is 74.64 (according to the OS map)
The site x is a farmers field. The rock in this area is chalk, which is permeable, so rainwater soaks into it. The evidence of the map that show is chalk is Chalkpit farm and Chalkpit Cortages.
The site x is a flat land. The area is mainly covered by forest. The land either side is steep land. The site can have V-shape valley.
The site x is currently use for farmers field and it also used by walking – footpath.
Using the A340 road and M4 motorway we can go directly to Tidmarsh. However, the Tidmarsh Lane is the only road that we can use to go to site x.
In order to prove the hypothesis is true or false, we will carry out experiments at site X, upstream at Hogmoor Copse and downstream at the confluence of the river Pang and River Thames.
What are the propositions and are they suitable?
In this section I will now look at the proposed development types and I will say if they are suitable. I will focus on the housing problem currently present in Reading.
This proposition is the development of six, five bedroom luxury houses.
* The houses would sell more for more money.
* This would attract the same group of peoples, which are living there.
* This type of house will not contribute for a big increase in traffic, crime and pollution.
* The houses can be brought wealth people and large families.
* The standard of living will be good because the houses are attractive.
* Poor access to housing for people with low income.
* It does not solve the problem in Reading.
The proposition two is the development of twelve, three and four bedrooms medium cost family housing.
* The houses would sell at good money.
* This preposition is cheaper than proposition 1
* Not will cause many complaints from the NIMBYs
* Would not cause arguments among locals.
* The road would become busier with more traffic. This means increasing of noise and pollution.
* Will be expensive to build.
The proposition three is a development of forty, one and two bedrooms low to medium cost key worker apartments.
* More access to housing for more people.
* There will not be such big problems about the housing in Reading as these will accommodate more people.
* This type of house is sustainable.
* Is cheap for tenants.
* Will bring more traffic and pollution.
* The crime would increase.
* It looks ugly from outside.
* May not be a nice place to live.
This are a development of thirty three bedrooms low cost council owned properties spread over four maisonette style flats.
* These will bring more children’s.
* The NIMBYs will not do complaining.
* Attract people on a low income.
* These houses are very unattractive.
* The roads need to change.
The final proposition is to reject the idea of building at site X and build nothing there.
* Not cost any money.
* The site X will continue to farming and agriculture
* There will not excess traffic or crime in this area.
* This does absolutely nothing to solve the shortage of housing in Reading and the surrounding areas.
* Lot of people will be upset.
* The business will not increase.
In this section I will show how the experiments carry out within the River Pang.
The experiments will carry out in the following sites:
* Site 1 – Hogmoor Copse
* Site X – Field on Sulham Hill
* Site 2 – Confluence the river Thames and River Pang.
1. Width of the River
Place a tape measure from 1 side of bank to another. It must be tight for get the more accurate measurement possible.
2. Depth of the river
Divide the river in 50cm intervals. Put the measurement stick inside of river doing on a vertical position until it touches the river bed. Then measure the depth of the river. I need to think about the rock on the bottom of the river.
3. Wetted perimeter.
The wetted perimeter is the amount of the water in contact with the river. Place a chain along the bed. Measure amount of chain that is used.
4. Velocity (speed)
Measure a section of the river in 10 meters long. Stand one person upstream and the other person downstream. One person drops the tennis ball and times how much takes to go to other person. Then repeat 2 more times.
5. Gradient (angle)
Measure a section of ten meters in the river. One person holds the clinometer and pulls the trigger from the top of his meter stick to the top of the other person’s meter stick. Then take the reading on the clinometer. Then repeat two more times.
6. Bedload sample
Take ten rocks from the river and measure them. I need to put the rocks that I have measured to the side and put back when I have measured the all ten rocks.
7. Questionnaires in Pangbourne
In groups of 4, each group surveys 10 people in Pangbourne using the questionnaire. I need to make sure the same person is not asked twice.
Analysis of the results
In this section I am going to analyse the results obtained on Site 1, Site 2 and Site 3
Width of the river
I expect the wider of the river decreases from Site 1 to Site 3 (upstream to downstream). The width of the river on site is 8.5 meters and goes to 3.7 meters. The site 3 is near to mouth of the river. The site 3 (PangBourne, confluence with River Thames) gets narrow because of human interfere. Human has placed Concrete to decrease the flooding risk.
Look at cross section area site 1 = 1.1 site 2= 0.9 site 3 = 1.1
As I said the width of the river decreases from upstream to downstream.
I expect the larger perimeter, the bigger the flood risk.
On site 1 the wetted perimeter is 9.1m site 2 is 7.3 meters, site 3 is 4 meters. The biggest risk of the flood is the site 1. The smaller risk of flood is the site 3 because the river goes quickly.
I expect to get higher bedload size on the site 1 and on the site 3 the smaller size. But on the site 3 the data collected show us that size is higher than site 3. This happens because the bricks and concrete are fallen from bank of the river.
The velocity of the river increase upstream to downstream. The site 1 shows a average of 27.07 seconds to ball goes 10 meters, site 2 shows a average of 28.2 seconds the last site 36.2 seconds. The Site 1 – Hogmoor Copse and Site 2 – Tidmarsh, where we intend to build, have a higher risk of flood.
We expect discharge increase as we move downstream. The site 1 and site 2 are more open which increases the evaporation. The below graph shows a decrease of discharge because on site 2 people may take water for farming and on site 3 more building the houses.
We collected 10 questionnaires. Most people say that Tidmarsh is not a good site of building housing. The residents think the best feature o is river. Most people say that the traffic is a big problem.
With that I can conclude that the building of house is not sustainable.
What physical factors affect the decision to build?
In this section I will look at big natural causes which affect the decision to build.
Currently, the rock type on the site x is chalk (permeable), land mainly rural, steep sites because the site x is a valley, and the land is using for farming.
The below graph will show the present storm hydrograph on site x
Storm Hydrograph at present on site x
The rock is chalk this means that the infiltration is more quickly. The vegetation catches the water by interception, this me shows long lag time that means surface run -off decrease.
The rock will be impermeable (concrete). This means quickly surface run-off to the river. This should increase the risk of flood. The deforestation will increase which means less interception by trees. Also, the view and the wildlife will be affected.
The following graph shows the after urbanisation storm hydrograph.
There is a small lag time which means the risk of flooding increase.
How river could be change
* Deeper channel
* Flood control – weir
* Diversion channel
* Remove sediment and debris, new concrete channel
This cost million. The government will not make this cost to protect the river from flooding.
What human factors affect the decision to build?
In this section I will look at the human factors which affect the hypothesis.
The transport is going to be a problem. Sulham Hill (the road which we use to go to site x) is narrow and has a high speed limit. In mean in this road pass 22 cars in 5 minutes. The road has a high traffic.
For building on site x we to do the following:
* Change speed limit. Currently is 60mphs.
* Crossing for children
* Speed bumps
This will cost lot of money.
How will the more housing affect the village?
When building housing, more people will need more shops. The business will be happy because more money will enter. However the business will be unhappy because more competition will increase.
The crime will increase because of teenagers. Also, the noise would increase, when building. The visual and air pollution are also the factors which we need to consider. The view is going to change for a view with houses and shops. The local residents are going to breathe polluted air which will bring diseases and complains. For the reasons of crime, air pollution and noise will bring more complains. The NIMBYS will protest because the house can go down.
More shops (which means more jobs) and parking will be required.
