Calibration is essential. Hydrologic models are not reliable unless they represent continuously observed watershed behavior in the region where they are applied. HFAM includes a variety of tools for calibration of model parameters. Design of Water Resource Facilities Designs are investigated with HFAM Analysis runs. These are long-term simulations of 30 to 80 years, depending on the available historic meteorologic data in the watershed.
Watershed behavior is modeled with and without new facilities.
Analysis runs show continuous streamflow, snowpacks, generation, diversions, and reservoir levels or volume. Statistical summaries of flood frequency, watershed soil moisture, snowpacks, streamflows, hydro generation, reservoir releases, and other time series are available. This plot shows the total snowpack water content above a reservoir during the spring snowmelt season. Snow water equivalent at a selected location and elevation can be plotted for comparison to a snow course or snow pillow measurement. This display shows a powerhouse that is operating on a user defined weekly schedule.
