In an enlarged urban stream, habitat structure is lost and flows become more shallow, slow- moving and indistinct.

Notes:
The channel enlargement process sharply degrades stream habitat structure and flows become more shallow, slow moving and indistinct. High quality streams have a series of pools, riffles, and glides that provide unique and stable habitat areas for different fish and aquatic insects. Urban streams are characterized by highly scattered and poor quality stream beds.
