Stream
First-order streams are perennial streams--streams that carry water throughout the year--that have no permanently flowing tributaries. This means no other streams "feed" them.
1st order stream with a small catchment and low drainage basin density, which flows into the River Severn
Characteristics
Land use
Agriculture 95% - pastoral sheep grazing, during the Victorian times woodland was completely cleared to make way for sheep for the woollen trade, there is now debate as to whether it should be returned to woodland through afforestation or remain as upland moorland habitat it currently is.
Recreation and Tourism – 5% - the National Trust took over the area 54 years ago and developed the café, gift shop and education centre. They also maintain the paths and the stream in terms of flooding defences.
Geology
Permeable precambrian sedimentary rock, the mountain acts as an aquifer, which means that the stream never dries up, even in the summer after 8+ weeks of no rainfall!

Low drainage density → Drainage density is the total length of all the streams and rivers in a drainage basin divided by the total area of the drainage
