DEF

A set of software and methods used to compute relationships between physical habitat and streamflow.

CONT

The hydraulic component is PHABSIM (physical habitat simulation), a set of computer programs that simulate hydraulic conditions and (with recent modifications) water quality at different flows, based upon field data and river hydraulic principles. In tandem, PHABSIM and HSI models are used to estimate the habitat availability for fish at different flows.

CONT

Instream Flow Incremental Methodology (IFIM) and Physical Habitat Simulation (PHABSIM). IFIM is a process for evaluating instream flows in the context of the entire ecology of the watershed, including hydrology, geography, and biology. PHABSIM is a modeling approach and tool for use within (or separate from) IFIM. The models are in PHABSIM.
