This summary is a 'quick tour' of HFAM . For additional information we recommend downloading the HFAM Demonstration software. Applications of continuous hydrologic simulation methods require time series of continuous hydrometeorologic data, and physical data on watersheds and facilities. To make handling these data as straightforward as possible, HFAM includes a comprehensive data base for hydro-meteorologic time series. Calibration of HFAM , matching continuous simulated and observed streamflows and snow depths, is done for all applications.
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.
