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 notits 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.

Question 2

A river slope or gradient adjusts to what three factors that it has no control over?
   a. stream width, depth, and amount of water
   b. water turbulence, channel roughness, and grain size of sediment
   c. water velocity, water temperature, and stream depth
   d. water velocity, grain size of sediment, and amount of sediment
   e. channel shape, channel cross section, and channel roughness
