6 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)

7 Location State where study is
Mention local towns, rivers, mountains nearby Map of Yellow water river Map of N.Ireland

8 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

9 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

10 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

11 Upper Course

12 Middle course

13 Lower Course

14 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?

15 Processes of transport
What is transportation? How does it affect the river? Features There are 4 processes: Traction Saltation Suspension Solution

16 Main river features Look at the main river features briefly ie.
Meanders Oxbow lakes How are they formed? Include diagrams?

17 Methodology How we are going to collect our primary data



20 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

21 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

22 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)

23 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

24 Data Presentation 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)

25 General Tables of all the results on spreadsheets Load
Velocity/discharge Width and depth Gradient

26 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

27 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

28 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)

29 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)

30 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

31 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)

32 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

33 Flow diagram showing the discharge of the river
Site 1 – 0.1 m³/Sec (1 cm on graph paper) Site 2 – m³/Sec (1.1 cm on graph paper) Site 3 – 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

34 Angles of the banks Scale 1cm:1m River Width site 3 = 8.3 cm
Left Bank Point Distance on graph Angle (°) 1 1.5cm 47° 2 2cm 10° 3 25° Site 1 Right Bank Point Distance on graph Angle (°) 1 1.4cm 51° 2 4.6cm 3 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

35 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

36 Depth of the river across the 4 sites

37 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?
