Many environmentally oriented groups who oppose water resources projects, have conceived various types of flow requirements to supposedly meet a variety of biological purposes in rivers. Examples of flow requirements include minimum flows for general preservation or enhancement of fish and terrestrial species, channel maintenance flows to prevent sedimentation and vegetative encroachment so that the conveyance capacity of a stream is maintained at current levels and flushing flows to maintain appropriate substrate for fish spawning. This paper focuses on the purpose of flushing flows, the physical processes governing the concept and steps required to determine if a flushing flow is needed and the magnitude of a flushing flow, if found to be needed.
