Introduction Location Background information/Theory Methodology Tables/Graphs/Data collected
Place in Geographical context
State where study is? Include 2 maps of N.Ireland (highlighting
Rostrevor) One drawn, one from computer Include map of Rostrevor area showing the
course of the Yellow Water river (computer and drawn). Highlight studied area
Ensure all maps are titled and labelled with keys (number them Figure 1 etc)
Location
State where study is Mention local towns, rivers, mountains
nearby Map of Yellow water river Map of N.Ireland
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
Data PresentationNeed to use the following graphs to show your collected primary data:
Line graphs
Piecharts
Tables
