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

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

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

Upper Course

Middle course

Lower Course

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

Main river features

Look at the main river features briefly ie.MeandersOxbow lakes

How are they formed? Include diagrams?

Methodology

How we are going to collect our primary data

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

Photos

Include photos of each site Label the photos with local features Photos should show you collecting the

data and using the equipment at each of the 4 sites

Hypothesis 1-4 Restate the hypothesis Methods used for each hypothesis Why method was chosen How it was carried out Diagrams to show how information was

collected (do after fieldwork)

Initiative

Why it was chosen? How was it done? – diagrams and photos

needed Results of work done – graphs; charts;

photos etc Interpretation of results Evaluation of work done
