River Pang
What does natural mean?
Natural means existing in or caused by nature; not made or caused by humankind.
What do you mean by non-natural/ man made?
Not of natural origin; prepared or made artificially
How will we assess the level of natural?
Natural River Pang
There are many natural features such as green plants and trees which indicate that it hasn’t been affected by man. There’s also the natural meander. There is an intercept with man-made features. (Tidmarsh)
Man Made River Pang
In this area you can see that it is affected by man because there is a road built next to the river and all green plants and trees have been cut down and also there is less space for the river to flood. There’s also a concrete river bed so that vehicles can pass through the river since it is not deep. This shows clearly that the natural features meet the man-made features in the river pang (Bucklebury Ford)
Introduction
River Pang is a small chalk stream river in the west of the English county of Berkshire, and a tributary of the River Thames. The river Pang is also a river which can be very dry in summer time because there is very little water in the river unless it is a rainy season and if it rains a lot there could be floods and draughts in river Pang. The river pang is 19 miles long. We are going to find many natural features because the river is very natural and there are various changes in speed as the river is flowing down. There’s also many man made features which can be spotted near the river Pang such as bridges built for people to cross over the river.
I think that I will also see many meanders and rapids. I will also see wide flood plains going down the river because the river would be naturally made to stop floods. I might also spot that the stone size changes near the river banks. The river’s velocity will increase as we go down the river because there is going to be more water closer to the end of the river.
There is quite a gap between Bradfield and Bucklebury.
In our field trip we stopped at : 1. New Farm 2. Frilsham 3. Bucklebury Ford 4. Bradfield 5. Tidmarsh 1 & 2 6. Pangbourne
Method
The width and perimeter was found by using a measuring tape and pulling it from one river bank to another to find the width but the depth was found by using a measuring stick and it had a half a metre interval. We found out the wetted perimeter by using a measuring tape from one river bank to another.
This is how the measuring poles are used to get the width and depth of the river.
Measured travelling speed of water in 10m per second.
Tennis ball used to find the velocity of the river. We only dropped the ball to find the speed of the water in some places. Although this wasn’t accurate since the ball got stuck in weed and it only gave us the flow of water on the top of the river.

The stones are larger in the water than the stones that are moved away from the water.
Clinometers are measuring devices also known as an inclinometer, the essential function of the device is to determine accurate measurements as they relate to sloping, height and distance. This device was used 10m apart from the poles and we took the reading from an angle which gave the readings in degrees. Since river Pang was a flat land river we didn’t get any readings because there was no slope.
After all measurements are made and numbers are crunched, the river flow can be classified.
Data presentation & analysis
Many man-made features could be seen here, this was because the water flow in this area had been slowed down.
