Introduction
Aims
I am going to carry out a piece of fieldwork on the Yellow water river. My aims for this fieldwork are: River study for GCSE COURSEWORK Study how river features change from source to
mouth Compare Yellow water river to rivers in our textbooks
![Page 9: Coursework Year 12](https://reader035.vdocuments.us/reader035/viewer/2022062314/56812b94550346895d8fb6b4/html5/thumbnails/9.jpg)
Our 4 HypothesesTo achieve our aims I will test the following 4 hypotheses:
• The load of the river decreases in size and becomes more rounded as we go downstream
• The river becomes deeper and wider as we go downstream
• The discharge and velocity of the river increase as we go further downstream
• The gradient of the banks decrease as we go downstream
![Page 10: Coursework Year 12](https://reader035.vdocuments.us/reader035/viewer/2022062314/56812b94550346895d8fb6b4/html5/thumbnails/10.jpg)
Theory and background
River in 3 sections:1. Upper Course2. Middle course3. Lower course
Relate theory to 4 hypotheses. In other words to:
Load Width and depth Discharge and Velocity Gradient

Processes of Erosion
1. Attrition2. Corrasion3. Corrosion4. Hydraulic Action Diagram of these processes How do they affect the river in the upper,
middle and lower courses?

Processes of transport
What is transportation? How does it affect the river? Features There are 4 processes:1. Traction2. Saltation3. Suspension4. Solution

The sites We will collect the data at each of 4 sites. Site 1 – Near the source in Upper course. Grid
Ref: 214, 224. (close to public pathway – easy access)
Site 2 – Upper to middle course. Near a picnic area (easy access). Grid Ref: 208, 222
Site 3 – Middle Course. In Fairy Glen. Public walk. Grid Ref: 188, 188.
Site 4 – Mouth of the river. Accessed from the beach. Grid Ref: 179, 181.
All sites in public areas, accessible without trespassing on private property
