Models of the IFIM include the Physical Habitat Simulation System (PHABSIM), Time Series Analysis Library (TSLIB), two temperature models: Stream Network Temperature Model (SNTEMP) and the Stream Segment Temperature Model (SSTEMP), SALMOD, and the Legal Institutional Analysis Model (LIAM). The various models are designed to give the user information required to select environmental flow needs. The models do not calculate an environmental flow need - selecting an environmental flow need is the responsibility of the user. PHABSIM is a set of programs designed to predict microhabitat conditions in rivers as a function of streamflow and the relative suitability of those microhabitat conditions to aquatic life. TSLIB programs provide data entry, analysis, and display of daily or monthly flow or habitat values. Some programs are useful for integrating microhabitat and macrohabitat, and some are of value in the analysis of water operations systems. SNTEMP predicts the water temperature in streams and rivers from data describing the stream's geometry, meteorology, and hydrology. It handles a dendritic network of streams through time and space. SSTEMP is a scaled down version of SNTEMP suitable for single (to a few) reaches and single (to a few) time periods. SALMOD is a computer model that simulates the dynamics of freshwater salmonid populations. Developed and used for the Trinity River, California, Chinook salmon evaluation, SALMOD has wide applicability for freshwater habitat-limited salmonid populations. LIAM was designed to accomplish three goals: (1) plan for participation in a negotiation, (2) predict organizational behavior, and (3) examine likely negotiation strategies.born digitalproceedings (reports)engCopyright and other restrictions may apply.
