Drainage density is determined by
A) dividing the number of streams in a basin by the basin area.
B) dividing the actual path length of a stream by the shortest path length of the stream.
C) averaging the discharge values across a drainage basin.
D) dividing the total length of all stream channels in the basin by the area of the basin.

Question

Quizplus · Accepted Answer

Drainage density is calculated by dividing the total length of all stream channels in a basin by the area of the basin. This provides a measure of how well-developed the stream network is within a given area. Option A is not correct because it only takes into account the number of streams in a basin, not the length of the streams. Option B does not provide an accurate measure of drainage density. Option C is incorrect as it averages discharge values, which is not directly related to drainage density.
