To study the effects of a forest fire on runoff characteristics, the Utah State University Watershed Simulation Model (USUWSM) has been applied to three small drainage areas in the Entiat Experimental Watershed which is located within the Wenatchee National Forest of central Washington. Each component of the USUWSM has been described in the report, including structural changes to the model that were necessary to achieve reasonable agreement between observed and simulated runoff hydrographs. Lack of information on the spatial distribution and precipitation due to the absence of an adequate precipitation gaging network on or close to the study area was a severe handicap to the simulation study. Only a very short period of post-fire streamflow record was available and thus it was possible to make only qualative conclusions regarding the effects of the forest fire on runoff characteristics.
