River Meden Fieldwork

What was the key question of the River Meden fieldwork?

• How polluted is the river?

• Do the characteristics of the River Meden change downstream?

• Is the River Meden a good tourist location?

• How many species live in the River Meden?

What theoretical model was used to compare river changes?

• River Drift Theory

• River Change Model

• Bradshaw Model

• Delta Formation Model

Which equipment was used to measure river depth?

• Stopwatch

• Flow meter

• Metre ruler and tape measure

• Measuring jug

How was flow (velocity) measured in the River Meden study?

• Stopwatch and float method (e.g. rubber duck)

• Pressure sensor

• GPS tracking

• Weighing water samples

What type of sampling was used for river velocity?

• Stratified

• Systematic

• Convenience

• Quota

What safety action was taken to prevent slipping in the river?

• Use of walking sticks

• Wearing helmets

• Sensible shoes and walking carefully

• Avoiding the river entirely

Overall the River Meden fits the Bradshaw Model in only​ (a)   of the 4 experiments. This could be because between the ​ (b)   and downstream measurements was a ​ (c)   whose supports could have been an obstruction causing the river to ​ (d)   and drop it’s load. This means the river would become slower and shallower and the angle to​ (e)   However the load size and roundness does fit the model as the load has still had to travel further and would have eroded along the way.
