Why does a stream bottom erode more deeply when its water level rises in a flood?
A)Since its water velocity remains the same, the increased volume of water can carry more sediment.
B)Its water level rises, so water velocity increases and it can carry more sediment.
C)It does not-its stream bottom builds up to match the rise in water level.
D)Its gradient becomes steeper, so it can erode deeper.
E)To accommodate the additional water, its velocity slows, and it digs in deeper.
