Base level of a stream is a balance of
A) stream power and sediment load.
B) velocity and discharge.
C) precipitation and infiltration.
D) runoff and evaporation.

Question

Quizplus · Accepted Answer

The base level of a stream is the point at which it can no longer erode its channel, so the balance of stream power (velocity and discharge) and sediment load is important in determining this level. Precipitation and infiltration, as well as runoff and evaporation, are important factors in determining the amount of water flowing in the stream, but they are not directly related to the base level.
