text: Vflo is a commercially available, physics-based distributed hydrologic model generated by [http://www.vieuxinc.com Vieux & Associates, Inc.]  Vflo uses radar rainfall data for hydrologic input to simulate distributed runoff. Vflo employs GIS maps for parameterization via a desktop interface.  The model is suited for distributed hydrologic forecasting in post-analysis and in continuous operations.  Vflo output is in the form of hydrographs at selected drainage network grids, as well as distributed runoff maps covering the watershed. Model applications include civil infrastructure operations and maintenance, stormwater prediction and emergency management, continuous and short-term surface water runoff, recharge estimation, soil moisture monitoring, land use planning, water quality monitoring, and water resources management.
