A stream will likely begin aggrading sediment along its bed when:
A)the flow remains constant while the sediment supply decreases
B)the flow and the sediment supply increase proportionately
C)the flow increases, while the sediment supply decreases
D)the flow decreases, while the sediment supply remains constant

Question

Quizplus · Accepted Answer

Aggradation occurs when sediment supply exceeds the transport capacity of a stream, leading to sediment deposition. This is most likely when the flow decreases but the sediment supply remains constant, as the stream's ability to carry sediment diminishes while the amount of sediment available for transport does not change.
