The Northwest Watershed Research Center is actively involved in the development of computer simulation models. Models and tools currently available are:
TheSimultaneous Heat and Water(SHAW) model simulates heat, water and solute transfer within a one-dimensional profile which includes the effects of plant cover, dead plant residue and snow. Unique features of the model include: simultaneous solution of heat, water and solute fluxes; detailed provisions for soil freezing and thawing; and a sophisticated approach to simulating transpiration and water vapor transfer through a multi-species plant canopy.
