Definitions:

Narrow Canyons

Deep, slender valleys with steep sides, carved by the erosive force of flowing water over geological time scales.

Downward Incision

The erosional process by which a river cuts deeper into its bed, often leading to the formation of a canyon or gorge.

Erosion

The process by which natural forces like water, wind, ice, and gravity wear away and break down earth materials, transporting them from one place to another.

Stream Deposition

The process by which sediment carried by a stream is laid down or deposited in new locations, often resulting in the formation of deltas and alluvial fans.
