Drainage density is determined by

Describe the common stream channel patterns.

The meaning of the terms "river" and "stream" sometimes overlap although, in general, the term "river" is reserved for channels of water larger than a stream.

Faulted and jointed landscapes directs streams courses in patterns of right-angle turns forming this drainage pattern.
