A Study of the Changes in River Processes

This is a study of the changes in river processes along the long profile of a river. To study this we will use a sample river. The river the study will be based on Loughton Brook, which is a river situated in Epping Forest in Essex and is also a tributary of the river Thames. A journey will be made to the river and measurements will be made at three different sites. The measurements that were taken will be studied so conclusions can be made about the changes to characteristics of a river with distance downstream.

Aims and Hypotheses

The overall aim of this study is to investigate the changes in river characteristics downstream along Loughton Brook. …show more content…

Also the shape of the three diagrams shows that the left side of the river is deeper than the right side. This may be due to erosion of the left side and deposition on the right side, which suggests that the flow of the river is faster on the left hand side than the right.

Graph 4 is the river cross-section diagram for Site 1. It shows that the river cannel is 3.5m wide and at its deepest point it is 0.23m deep. The shape of the riverbed can be seen using this graph. It shows that the left hand side measurement of the river is deeper at 0.23m than the right hand side measurement at 0.085m. This difference of 0.145m may be due to the erosion and deposition on the riverbed.

Graph 5, the diagram for Site 2, shows that the river channel is 3.4m wide which is 0.1m narrower than at Site 1 and also the river is 0.22m deep at the deepest point which is 0.01m shallower than the measurement for Site 1. The left side is deeper than the right side like it is in Site 1. The left side measurement is 0.22m deep and the right side measurement is 0.09m deep. Again the difference of 0.13m may be due to erosion and deposition.

Graph6 is the cross-section at Site 2. The diagram shows that
