ABSTRACT-The Peatland Hydrologic Impact Model (PHIM) is a continuous simulation computer model developed over a twelve-year period to aid hydrologists in understanding the hydrologic functions of peatlands and upland-peatland watersheds. An initial conceptual model defined the research needed to create the working m?del. The re~e_arch has become an iterative process of model design, field work, model refinement, ~ode! test1?g, an~ add1t1?nal field work. The model is as physically-based as possible while relying on data mput that 1s readily available to the natural resources community. It simulates streamflow response of peatlands, upland-peatland systems, mined peatlands, and a combination of these watershed units.
