Aerial photographs of footpaths & erosion – this allows us to see where the biggest amount of footpath erosion is Description of method: Tripping on footpaths – wear hiking and bring a first aid kit Look at an OS map and select a footpath – Getting lost mobile phone and OS map Use systematic sampling to select three points 500m apart from each other Advantage of location: At each site place a tape measure across Close to school – collect lots of data the footpath and split the distance by 10. quickly and easily a ruler measure across the footpath In a National Park so there are easy to at each point access footpaths which will help to Repeat for each point and then at each collect lots of data site Justify the method: Data presentation: Systematic sampling – to reduce bias in Drew a cross-section for each site – this selecting sites looks like a line graph Transect – away from Bakewell to help Draw a transect line and then located with identify any patterns an arrow each of the cross-sections on it Easy method to do Positives: No expensive equipment Easy to see changes down the transect Negatives Time consuming to do Complicated to draw Conclusion: Footpath does not decrease away from Bakewell Site 1: Average erosion 20 cm Site 2: Average erosion 15cm Site 3: Average erosion 10cm Reasons for this: Less walkers the further away from Bakewell as tourists do not want to walk that far away from the town. Change in rock type – rock gets harder the further away from Bakewell Evaluation: Problems Issues with the methods: Ruler not easy to read One person measuring - not accurate when reading the Issues with the results: Less accurate as the measurement was only taken once Only one footpath so not easy to get a clear idea of how the other footpaths near Bakewell change
