Line thickness & shade map Strahler stream order, which is a measure of how many streams merge into a given channel. Highest order are small headwater creeks, while largest are the great rivers of the world (i.e., Amazon, Congo, Nile). Lakes are a consistent light blue.
Tools: QGIS and R
Sources: HydroRIVERS/HydroLAKES (HydroSHEDS).
Looks cool. No clue what the Strahler Stream Order is but I assume that it’s based on water flow?
Looks good, but as an Australian, many of those ‘rivers’ do not flow generally. They are channels that carry water once or twice a decade.
And that, kids, is why Australia has a population of 25 million while the US is about the same size and has a population of 300+ million.
