On the second day of our recent visit to Preston Montford, we explored the Bradshaw Model, and the different changes downstream. Most of these were shown on the classic diagram which can be seen below.
We decided that we would focus on one particular aspect of the model: the changes in the channel width and depth with distance downstream. We could have explored bedload size too, but we also calculated discharge using impellers and flow meters.
The area is managed by the National Trust
We waked up the valley to Lightspout Waterfall.and then made our way down taking readings.
We outlined a systematic sampling strategy which was to sample every 200m from the waterfall.
Results are now in, and we will share some of these over on my OCR Geography GCSE blog.
Remember that in addition to this blog, I also have my classroom blog as well.
