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

Question

Quizplus · Accepted Answer

Drainage density is defined as the total length of all stream channels in a basin divided by the area of the basin. Choice A is incorrect because discharge values do not necessarily reflect the density of the drainage network. Choice C is incorrect because it is describing the sinuosity of a stream channel rather than its drainage density. Choice D is incorrect because the number of streams is not necessarily a good indicator of drainage density, as some basins may have many small streams while others have fewer but larger streams.
