The concept of a graded river profile is based on which balance?
Answer and explanation
Correct answer: A long-term balance between sediment load and stream energy
A graded river has adjusted its slope, channel form, discharge, and sediment load so that, over time, erosion and deposition are broadly balanced. It is not completely inactive: floods or changes in sediment supply may disturb the profile, after which the river readjusts. Thus option A correctly expresses the relationship between stream energy and transported load; the other balances are unrelated.
