Intoduction On the following pages I have collated all of the data collected from our river study. I have started with a table of raw data which I have then refined and finally I have taken each measurement and presented it in separate graphs. Stop 1 G.R.-511 808 Stop 1 has many different types of rocks e.g. granite, marble, sedimentary, igneous and metamorphic rock. These rocks slow down the river and the river uses most of its energy to overcome these rocks. There is also boulder clay which vegetation has formed on top of. This stop has its own micro climate compared to the mountain top. This enables Mountain Ash to grow which is the first tree growing down the mountain because it is sheltered in the V-shaped valley. Some of the features found at this stop include interlocking spurs and V-shaped valley. The land surrounding the river is the river's watershed and underneath it is peat. From this stop I can see the source of the river. Stop 2 G.R.-512 805 This stop is similar to Stop 1. ...read more.


Stop 6 G.R.- 521 801 At this stop, there are slip-off slopes and a definite meander. There are small river cliffs and this overhanging material will eventually fall off and be carried downstream. Plunge pools and waterfalls are also features which can be found at this stop. Stop 7 G.R.- 525 799 At this stop, there is a sharp meander as the river spreads out as the valley widens with the V-shape becoming less apparent. There are more rock features and also distributaries as the river tries to find the place of least resistance in its journey down through the mountain. Stop 8 G.R.- 531 798 Here, there is huge deposition of rocks as shown by the photograph with many grasses also present at this stop. The river has now become wide and the valley becomes a U shape rather than the V-shape at earlier stops. Stop 9 G.R.-534 799 There is a large amount of deposition of rocks happening at this stop. There is also a man made lane along side the river and the river is covered by a large number of rocks. ...read more.


The average velocity is the same for both Stops 1 and 2 at 21mph. The average then falls before rising and rising again to reach 0.2mph. The average velocity keeps rising to reach the highest average gradient at Stop 8 at 0.28mph. The average then falls at both Stops 9 and 10 to finish the average velocity at 0.06mph. The long axis for the average pebble size at Stop 1 is 15.15 which then rises to 19.7 which is the largest average pebble size for the long axis. It then falls before rising slightly and then rising again. It then falls but rises again before falling to a measurement of 7.81. It then rises again before falling again to an average pebble size for the long axis being 9.1. The short axis for the pebble size starts at 2.16 and then it rises significantly to 10.26 but then falls at Stop 3. It then rises slightly and then rises again before falling and rising and falling again. It rises again on Stop 9 to 5.94cm and then falls again to 2.54. ?? ?? ?? ??

    At a velocity of 10 cm/second, sand would be transported but would not erode, whereas if the river had a velocity of 0.5 cm/second, the sand particles would be deposited. Q: What factors determine the efficiency of a river? Suggested Answer The efficiency of a river is determined by: velocity, friction, the wetted perimeter and the channel shape.

    However, graph eleven clearly shows that the modified channel is slower at twelve point three seconds compared to the natural channel which had a float time of seven point nine. Consequently I cannot back this up. Graph 2 From graph two I can see that the cross section of the natural channel has a smoother surface than the modified channel.

    material a possible better way to measure it is by taking the surface area. This would be much more accurate, but more time consuming and unpractical when there is a limited amount of time to collect data. The other quarrel is that to get a better impression of the size

  2. Do the Characteristics of a river change downstream?

    Surrounding the area where we will be working is mostly moorland. The climate at Backstone Beck is likely to be more varied than that in the valley because the valley sides do not shelter it. There should be more precipitation in general.
