Analysis of Data - Showing what my Graphs show

RG1 - From looking at this graph I can say that from site 1 to site 2 the width in the river increases from 8 to 9 m which means that the river is getting wider by a total of 2m. After this point on the graph between site 2 and 3, the stream width of the river lies stable at 9m which shows that the river width is steady. The river then starts to get wider at site 4 to 10m and then suddenly decreases to just over 7.25m. Between site 5 and site 8 I can say that the width of the river has gotten wider by a total of 7.04m. From this inclination I can say that the general trend of the river width shows that the river pattern is not fluctuating too much in terms of the width constantly changing from decreasing and increasing but is instead increasing at a steady rate. This means that generally as you go downstream from site to site the width of the river is increasing. Furthermore, from looking at this graph I can also pick out that the river is getting wider through lateral erosion which simply means that the banks of the river are getting eroded side ways through the knocking of the bedload from side to side. Other processes of erosion that are occurring are attrition which is the knocking of rock fragments in the water against one another and then are made into smaller pieces and become smoother. This process is most likely to be happening from about site 6 onwards as this is where the river velocity is at its fastest. Hydraulic action is also likely to be happening as water here is also fast moving. This means that rocks are breaking down quickly and are dragged away from the bed and banks by the force of the running Water itself. When the water from a fast moving stream enters the rock, it cracks it and the force breaks up the rock into smaller ones.

RG2 - By looking at the depth graph I can pick out that site 1 is deeper than site 2. The graph then shows that from site 2 to about site 8 the general trend of the graph shows that the river is getting deeper. Generally I can say that apart from site 1 which looks to be an anomaly compared to the general trend of the river shape I can say that the river stream is getting deeper as you go downstream.

I now that the river is getting wider as you downstream because many different types of erosion are occurring such as attrition, corrosion and carrasion is happening. Carrasion, also known as solution, is the process by which the river water reacts chemically with soluble minerals in the rocks and dissolves them. This process is very likely to be happening at site 5 and onwards. This is because the water in the river must be travelling at high speeds in order to break down such tough bedload. Hydraulic action is also likely to be happening downstream of the river ...
