Question

Quizplus · Accepted Answer

Incised meanders are formed when a stream cuts vertically downward into its bed, creating a deep, narrow channel. The meanders retain their sinuous pattern as the stream incises its way downward. Excised, excavated, and concentrated meanders do not necessarily retain their original sinuosity as they are modified by different processes. Superposed meanders are formed when a stream erodes through an existing ridge, so they may or may not retain their original pattern depending on the structure of the underlying rock.
