Study Notes
Meandering Streams and Rivers
- Coupled erosion and sedimentation in a watercourse result in the formation of a meander belt.
- The zone within which a meandering stream periodically shifts its channel is known as a meander belt.
- The sinuosity of a watercourse is measured by dividing the length of the channel by the length of the valley.
- A sinuosity of 1.5 or more defines a meandering stream or river.
- The term 'meander' derives from the Meander River in Turkey, which was known for its winding course.
- The sinuosity of a watercourse is defined by its ratio of channel length to valley length.
- Meander belts are areas within which a meandering stream periodically shifts its channel.
