Coursework Year 12 Introduction and theory
Contents page • 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 Hypotheses To 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: • Upper Course • Middle course • Lower course • Relate theory to 4 hypotheses. • In other words to: • Load • Width and depth • Discharge and Velocity • Gradient
Processes of Erosion • Attrition • Corrasion • Corrosion • 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: • Traction • Saltation • Suspension • Solution
Main river features • Look at the main river features briefly ie. • Meanders • Oxbow 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
Need to use the following graphs to show your collected primary data: Line graphs Piecharts Tables Scattergraph Cross-section of rivers Diagram showing changing width Bar chart (width/depth) Cross-section of the river Flow diagram of discharge Table (angles of the banks) Diagram of angles of the banks Photographs (labelled) Data Presentation
General • Tables of all the results on spreadsheets • Load • Velocity/discharge • Width and depth • Gradient
Load • Pie charts of the Power shape Index for each site (1-4) • Figures entered in as percentages • Table of the Power shape index of the load • How many rocks are very angular, angular, sub angular etc
Load (continued) • Table of the length of the long axis and figures for all 20 stones at each site • Scatter graph and Radar graph of this data
Load (continued) • Table of the Roundness Index of the Load • Scattergraph and Radar graph • Cross-section of the river at each site (drawn on graph paper)
Width and depth Bar charts of the • Width, • Bankful width of the river at each site • Average depth Flow diagram showing changing width across the 4 sites (on graph paper) Cross-section showing the changing depth of the river across the 4 sites (on graph paper)
Discharge and velocity • Flow diagram of the discharge of the river (on graph paper) • Line graphs of • Average discharge at the 4 sites • Average velocity at the 4 sites
Gradient –angles of the banks • Results table of the angles of the banks for each site (1-4) • (On graph paper) Angles of the banks cross-section drawing for each site (1-4)
Flow diagram showing the changing width of the river • Site 1 – 4.9 m (2.5cm on graph paper) • Site 2 – 5.1 m (2.6cm on graph paper) • Site 3 – 8.3 m (4.1cm on graph paper) • Site 4 – 12.2 m (6.1cm on graph paper) Leave 40 squares between each site Scale Width: 1cm: 2m Length: 2cm: 1km
Flow diagram showing the discharge of the river • Site 1 – 0.1 m³/Sec (1 cm on graph paper) • Site 2 – 0.11 m³/Sec (1.1 cm on graph paper) • Site 3 – 0.32 m³/Sec (3.2 cm on graph paper) • Site 4 – 0.5 m³/Sec (5 cm on graph paper) Scale Width: 1cm:0.1m³ Length: 2cm: 1km
Angles of the banks Scale 1cm:1m River width site 1 = 4.9 cm River Width site 2= 5.1 cm River Width site 3 = 8.3 cm River width site 4 = 12.2 cm
Cross-section of the river at each site Scale Vertical: 1 cm: 5 cms Horizontal: 2 cms: 1 m Site 1 Width 4.9 m (49 squares on the graph) 17 readings of depth – depth rerading every 2.9 squares across Site 2 Width 5.1 m (51 squares on the graph) 17 readings of depth – depth reading every 3 squares across Site 3 Width 8.3 m (83 squares on the graph) 17 readings of depth – depth reading every 4.9 squares across Site 4 Width 12.2 m (122 squares on the graph) 17 readings of depth –depth reading every 7.2 squares across
Data Interpretation • Look at each hypothesis in turn • State the hypothesis • Say what you expected to find • Say what you actual found • What do your results mean?
