Stop 3 G.R.-513 804
The valley here is more open and less confined as it is 2 to 3 times the size of the valley in Stop 1. It is also less steep. The underlying material at this stop is not solid. The river is meandering steeper around the hills. There is many ferns and heather. Some of the features found here include interlocking spurs, V-shaped valley, meanders and step like waterfalls as the river meanders down its course.
Stop 4 G.R.-514 803
At this stop there is a land slip at the side of the river which makes rocky beds. The V-shaped valley is also less steep but the river is wider than previous stops. Heather is not as abundant as previous stops and there is no Mountain Ash trees.
Stop 5 G.R.- 517 801
Here, the V-shaped valley is getting wider and less steep. The water is also getting deeper as the river is now entering its middle course. The vegetation is also becoming a lot greener as there is more grasses and other types of vegetation.
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. In addition, there is an increased amount of heather (bog) vegetation growing in the river.
Stop 10 G.R.-536 804
The deposition levees at this stop form a distinctive bank. A man made lane is still along side the river. The land surrounding the river is also flat and all the hills are gone meaning there are no V-shaped valleys. There is much deposition also. There is farmland near the river as the river has progressed into its middle course.
On this and following pages are five graphs, one for each of my five measurements. It is refined data for each of the ten stops. Also, after each graph there is a description of it.
From the above graph we can see that the average width at Stop 1 was narrow at 60cm before rising to 150 before falling again and then rising to reach the largest width of 175cm. The width then fell and rose again before finishing with an average width of 140 at Stop 10.
The average depth at Stop 1 is 10cm. The average depths then falls slightly to 9cm before returning to 10cm. It rises then to reach 15.33cm before the average then falls for the next two stops. It then rises significantly to reach the largest average depth of 23 before falling, rising and then falling again to finish the average depth at Stop 10 being 8.67.
The average gradient in degrees begins at Stop 1 being 8 before falling slightly and then rising significantly to the highest average gradient of 14.5 degrees. It falls in Stop 4 before being staying the same for both stops 5 and 6. It rises before falling again and then rises and falls again. It then falls for the second consecutive time finishing on a gradient of 2 degrees which is the lowest average gradient.
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.
