text: Vflo is suited for distributed hydrologic forecasting in post-analysis and continuous operations.  Vflo models may be calibrated by loading precipitation maps for historical events and comparing simulated volume/peak hydrographs to observed hydrographs.  Elevation data are taken from a digital elevation model.  A vector channel representation is employed.  Parameterization utilizes digital data sets at any resolution, including LIDAR terrain data and other digital maps of impervious area, soils, and land use/cover.  Vflo is developed to utilize multi-sensor inputs from radar, satellites, rain gauges, or model forecasts.  The kinematic wave analogy is used to represent hydraulic conditions in a watershed.
