Page 12 of 59 Sequence of work Start Firstly we established our aims and hypotheses before embarking on this trip. If there was a lot of rain or no rain at all, then this factor would be taken into consideration when our data was analysed. Overall, we can see that the river increased in width from 0. These will be the width of the river channel, the average depth, velocity, volume and the gradient. We did not use a bar graph to represent this data because they are used to track changes over time. River holford coursework Evaluations of river coursework river holford introduction for geography coursework geography geography coursework introduction example. At site 5 the five readings taken across the width of the channel were quite varied.

In order to measure the width, we had to face upstream and measure from left to right. It only required two people to measure the width and so the other members of the group were writing down the readings in meters. The reason that this was not undertaken was because of the limited amount of time we had to sample the river.

Between Sites 1 and 6 relatively even sampling was possible as accessibility was not a problem. These will be the width of the river channel, the average depth, velocity, volume and the gradient.

The middle course is less steep when compared to the upper course.

This meant that river holford coursework impeller turned faster then normal and therefore altered our results. Improvements If I were to repeat this river study again there would be some changes that I would make in order to improve my data.

Site 6- At this site, there was a rapid increase in the velocity of the river. This is the rapid down cutting of the bed. This reading could be seen as an outlier. The width river holford coursework a river channel increases as it goes downstream because tributaries and confluences join into it, thus making it wider because it holds more water. Where relevant, a good knowledge of sampling techniques is evident.

As you can see from the table above, my hypothesis was accepted visually by looking at the gradient graph which can be found on page An average depth graph can be seen on page 33 which supported my hypothesis by showing an river holford coursework as you got close to the mouth. This can be seen in the width graph river holford coursework page 39 which supported my hypothesis by showing a general increase from the source to the mouth.

There were lots of objects such as tree branches in the river. The river gets more powerful as you go down its course which means that it has more erosioncapability.

Page 1 of 59 An investigation into how …. However, too much secondary data should be avoided as should river holford coursework investigations that rely heavily upon observation without measurement.

At some sites we were very near to confluences and this could have affected our river holford coursework. As you can see from the table above, this hypothesis was visually accepted by looking at width graphs.

The depth then increased after reading 2 until 4 river holford coursework it was at its highest of 0. An explanation of why this outlier occurred may have been because there were many objects such as tree branches in the river which could have caused river holford coursework build up of water where we were measuring the depth.

Page 12 of 59 Sequence of work Start Firstly we established river holford coursework aims and hypotheses before embarking on this trip. Near the mouth of the River Holford, the Bristol Channelwe expected the river to be slightly shallower than at the previous sites because it was losing its energy and was depositing its load, sediment.

These points were at regular intervals. In the lower course of the river more lateral erosiontakes place which means the river cuts sideways into the valley. Page 31 of 59 The depth at site 6 generally decreased from 0. Published on Mar 31, The depth then decreased at reading 5 by 0.

An investigation into the changing physical characteristics form source to mouth of the River Holford.

However, as the river continues downstream there is less substrate on the bed which means that there less energy waste on friction. It enters the Bristol Channel.

The result was then plotted on the significance table below in order to be assessed. Page 4 of 59 Introduction In my introduction I river holford coursework be talking about where in the UK the River Holford is situated and the describing the relief around it.

Page 1 river holford coursework 59 An investigation into how physical channel characteristics change throughout the course of the River Holford. The clasts were all angular here and the geology was Devonian Quartzite.

The depth then decreased until reading 5 where it was 0. You can also see the rate at which the river is decreasing in gradient with this type of graph. Page 55 of 59 In this section I will be seeing if my hypotheses were correct overall using data from my graphs. Page 8 of 59 OS map 9. The Bristol Channel islocated inthisarea here. Some readings were defaulted at seconds because at some sites, the water was too shallow for the impeller to go in. Page 1 of 59 An investigation into how ….

The geology in this area was Quartzite and the gradient was decreasing. The depth then increased after reading 2 until 4 where it was at its highest of 0. Page 47 of 59 Possible Explanations for width results There are many possible explanations for why the width of the river followed the trend which can be seen in the graph. Page 10 of 59 Geology and site map The depth increased by 0. The geology here was still Marl. The results were combined and then averaged out.

Page 40 of 59 Gradient along the eight sites of the river Holford I have chosen a line graph to show the gradient of the river Holford because it is very easy to see if the gradient was river holford coursework or decreasing.

This is why you would expect a wider channel in the lower profile of the river. Published on Mar 31, River holford coursework map tells us that the source is m high and the mouth is not elevated at all. Then the angularity of the clasts were measured by using the cailleux roundness index chart. In the lower course of the river more lateral erosiontakes place which means the river cuts sideways into the valley.

Limestone is well jointed which means that river holford coursework rock has vertical and horizontal bedding planes.

Page 36 of 59 At site 5 the river holford coursework sectional area was 0. Page 54 of 59 Conclusions and Evaluation However, we could have compared our data with the other groups completing the same study to see if they got mainly the same results as us, and this would improve the reliability of the sample.

The information river holford coursework in this directory is provided river holford coursework on deafness to support the academic, administrative river holford coursework online writing workshops and business activities of the University of Adelaide. The geology in this area was Quartzite and the gradient was decreasing. The use of graphical techniques is limited.

River holford coursework this was not a site and we did not sample here, we can tell that the clasts are smooth and that there is a downward gradient as the water goes into the Bristol Channel. On the other hand, the sites which were in open farm land were expected to have a wider channel because there would be little or no interception from trees and vegetation.

Hypothermia Suitable warm clothing such as, woolly hats and gloves were worn when we were outside on the field trip. Once again there has been a change in underlying geology but there is also the added factor of human influence. Sign in or Register. River holford coursework could have compared data with other groups taking part in this study to see if we all got similar results and trends.

Nearly all the gradient readings are near the line of best fit which means that the correlation is strong.

This can be seen at site 1 where the width was 0. This can be seen in the width graph on page 39 which river holford coursework my hypothesis by showing a general increase from the source to the mouth. Simply looking river holford coursework the line of best fit will tell us if there is a strong positive relationship, no relationship, or a negative relationship between the two variables.
