Flashcards in The Hjulstrom curve Deck (4):
What does the Hjulstrom curve represent?
relationship between river velocity and competence. As well as how the processes of erosion, deposition and transportation vary with river velocity
Critical erosion velocity curve shows what?
Minimum velocity needed for the river to pick up and transport particles of different sizes
Higher velocity is needed to erode material, than to just transport it.
Settling velocity curve shows what?
Velocities at which particles of different sizes are despite
Competence of the river at different velocities
