Shape of a River - Geomorphology
Habitat (pg 1 of 2)

The free play of a stream's hydrodynamic forces creates a rich diversity of habitats for aquatic life. This diversity results from variation in stream depth, width, water velocity, and substrate throughout the channel, (the antithesis of a channelized ditch). Diverse habitats support a high degree of biological diversity.

The formation of meanders causes scouring and deepening of the channel along the outside bend. These deep main-channel locations, where fine sediment has been cleared away, are important holding and feeding locations for many species of fish and invertebrates.

The creation of eddies and deposition of fine sediment on point bars on the inside of river bends create slack-water habitat used by many species.
