Gcse Geography River Coursework Conclusion
It only required two people to measure the width and so the othermembers of the group were writing down the readings in meters. Page 18 of 59angularity and size of bed loadfirst, 15 clasts were picked up from the river bed at random, with our eyes closed sothat we were not biased in the selection of the clasts. Sw from this, the river calder passes sandholme mill, intersecting with the m6 motorway around grid-reference 52435.
Spearmans rank formula written in mathematical notation page 44 of 59my hypotheses were1. The river would havehad more energy to erode the banks and therefore widen the river. Overall, visually, my hypothesis, that the width will increase as you go fromsource to mouth, is accepted.
This sampling method allowed us to find out the impacts afterconfluences and if there was a difference in other factors such as depth in areas ofdifferent geology along the rivers course. Primary datared data secondary data clipping is a handy way to collect important slides you want to go back to later. A randomsampling method was used to measure the clast size at each site so that we were notbiased when collectingthe data.
Plot 6 was an unexpected rapid increase in the depth which was anoutlier because it was outside the range of the other results. Thistechnique tells us whether the correlation is really mathematically significant or if itcould have been the result of chance alone. Depth- we chose to take five depth readings at each site as one would not beenough to give an average reading.
Rank is a statistical technique which is used to see if there is a correlationbetween the results and to see the reliability of this relationship between them. There is an overall positivecorrelationwhich can be seen in the graph which is that, as the distance from thesource increases, the depth also increases. Page 43 of 59in this section i will be analysing my results to see if my hypothesis were correct andusing spearmans rank correlation to show the reliability of my results.
From quarry, the river calder begins to meander sw passing through oakenclough on grid reference 5547 passing calder vale further south. This meant that interception by this canopy layercould stop rain water from reaching the ground and therefore decreasing surfacerunoff. This happens by the force of water that is summoned during the storm resulting in hydraulic action which breaks parts of the boulders into rocks. Page 46 of 59significance testinga further technique is now required to test the significance of the relationship. As a result of thislimitation some of the velocity readings were defaulted to 100 seconds.

You can also tell where the deepest partof the river was along each of the eight sites. The impeller wasplaced onto the hydroprop, and then put two thirds of the depth into the river in orderto prevent the impeller from touching the bed. There was an unexpected drop in the depth of the river at the 5th plot where itwas 0. As you can see from the table above, this hypothesis wasvisually accepted by looking at depth graphs. Page 15 of 59justificationof methodsthere are three types of sampling methods which could have been used on this riverstudy and are a random method, a systematic method and a stratified method.
Therefore i still maintain my hypothesis and my explanation is thus as follows. This is why you would expect a widerchannel in the lower profile of the river. Page 22 of 59site 3- at this site, the river widenedconsiderably when compared to site 2 butstill stayed relatively the same depth. This tells us that the depth of the river will decrease at the sites wherethe geology is limestone. Site 1 is a smallstream which had very little depthand width because it had not rainedprior to our trip.
Plot 6 was an unexpected rapid increase in the depth which was anoutlier because it was outside the range of the other results. The depth of theriver was calculated using a ridgedmeter ruler and it was predictedthat as we continued downstream,the river would get deeper. However, as the river continuesdownstream there is less substrate on the bed whichmeans that there less energy waste on friction. You can also see the rate atwhich the river is decreasing in gradient with this type of graph. Page 46 of 59significance testinga further technique is now required to test the significance of the relationship. Nationalparksomerset is home to exmoor national park which is 693 km2 and is only one oftwelve national parks in the united kingdom. The width of the river will increase as you move from the source tomouth. This meantthat, especially in the upper course sites that the readings had to be defaulted at 100seconds. Now a statistical test calledspearmans rank correlation must be undertaken to see the strength of thiscorrelation.
