What is the title (aim) of our physical enquiry?
Investigate an urban regeneration project in Farnham
Investigate changes to the characteristics of the River Tillingbourne along it's long profile
Investigate changes to the River Tillingbourne's characteristics at natural and man-made locations
There is no change to the river channel cross profile of the River Tillingbourne along it's long profile
Which of the following is hypothesis 2?
There is no change in river discharge, and sediment size and shape along the RiverTillingbourne.
There is no change to the channel cross profile of the River Tillingbourne.
There is no evidence of human interference along the River Tillingbourne.
There is no evidence of deprivation in the Brightwells area of Farnham.
Which of the following were risks associated with the physical enquiry into the River Tillingbourne?
Disease caught from contaminated water (e.g. Weil's disease)
Injury or allergic reaction from horses
Drowning
Being hit by a car whilst walking down / crossing roads
Which of the following techniques was used to judge sediment shape?
Cailleaux's roundness index
Power's scale of roundness
Callipers
Group assessment
When working out the distance between depth measurements across the river, what number did we divide the width of the river by?
8
9
10
11
By collecting 10 pieces of sediment at 10 different points across the river that were equidistant from each other (same distance apart), what sampling method where we using?
Random
Systematic
Stratified
None of the above
When we chose our three sites to collect river data, what sampling methodology did we use?
Random
Systematic
Stratified
None of the above
When collecting velocity measurements, what was our sample size?
1
2
3
4
Which of the following is NOT a valid justification for using the lollipop stick method for determining velocity?
It's cheap and easy to conduct
It measures surface velocity, which allows us to compare velocity at different sites
Taking 3 measurements allows us to calculate an average to reduce impact of anomalies
The velocity of the river at the surface is the same as the velocity below the water
How did we use maps to help our investigation?
Helped us choose and navigate to our chosen sites
Helped us to interpret land use surrounding the river (natural vs man-made)
Allowed us to present our sediment shape and discharge data spatially (i.e. over space)
Helped us to complete our risk assessment
What data did we overlay as proportional shapes above our cross profile diagrams?
Sediment shape
Sediment size
Velocity
Cross-sectional area
Which of the following is NOT a core reason we chose the River Tillingbourne and the 3 sites along it?
Our teachers had extensive knowledge and understanding of the river - helping us to analyse our data.
It is a beautiful location in the Surrey Hills
The river is relatively small and accessible and so safe to conduct fieldwork in.
The sites we could access were suitably spaced out at different points along the river's course allowing us to test our hypotheses.
Most people found the cross sectional area of the river increased downstream. This was because... (pick two)
The river was widened by local people
The hydraulic radius also increased
The river drains an increasingly large area so there is more water
The width and the depth increased
Which of the following did we find decreased downstream from source?
Width
Depth
Velocity
Sediment size
What does the hydraulic radius tell us?
What the wetted perimeter is
How easily / efficiently the river is flowing
How many pieces of sediment are in contact with the water
When helping to explain changes in the characteristics of the River Tillingbourne, which theory/concept is most helpful?
Bradshaw's Model
Power's Scale of Roundness
Erosion, Transportation and Deposition
Long and cross profile
