Which of the following is the correct definition of stream gradient?
A)the water pressure at the bottom of the stream divided by the stream's width
B)the increase in discharge of a stream per unit drop in elevation
C)the distance traveled by water in a channel times a drop in elevation
D)the drop in elevation of a stream divided by the distance the water travels

Question

Quizplus · Accepted Answer

Stream gradient is defined as the drop in elevation of a stream divided by the distance the water travels. It helps to determine the slope and speed of the stream, and thus the erosional power of the water. Option A and C are incorrect because they do not take into account the distance traveled by water or the width of the stream. Option B refers to the concept of hydraulic gradient, which is different from stream gradient.
