Riverscape
A riverscape comprises the features of the landscape which can be found on and along a river. Most features of riverscapes include natural landforms but they can also include artificial landforms. Riverscapes can be divided into upper course riverscapes, middle course riverscapes, and lower course riverscapes.
The term riverine is sometimes used to indicate the same type of landscape as a riverscape, or only the riverbank. Riverine landscapes may also be defined as a network of rivers and their surrounding land, which is excellent for agricultural use because of the rich and fertile soil. The word riverine is also used as an adjective which means "relating to or found on a river or the banks of a river".
Upper course
In the upper course of rivers, channels are narrow and gradients are steep. Vertical erosion is the prominent land-forming process. Typical features of upper course riverscapes include:- Interlocking spurs
- Braided channels
- V-shaped valleys
- Giant's kettles
- Plunge pools
- Alluvial fans
- Tributaries
- Waterfalls
- Potholes
- Gorges
- Rapids
Middle course
In the middle course of rivers, the discharge increases and the gradient flattens out. Typical features of middle course riverscapes include:- U-shaped valleys
- Riparian forests
- Slip-off slopes
- Oxbow lakes
- Tributaries
- Cut banks
- Meanders
- Marshes
- Riffles
- Pools
Lower course
In the lower course of rivers, the channels are wide and deep, and the discharge is at its highest. Typical features of lower course riverscapes include:- Wide flat-bottomed valleys
- River groynes
- Large bridges
- Distributaries
- River deltas
- Floodplains
- Meanders
- Levees
- Kolks
