Abstract
 National Hydrography Dataset -Based RiverSpill Track: Water Resources Author(s): Rakesh Bahadur, William Samuels, Michael Monteith The RiverSpill time-of-travel spill model is being updated to use the National Hydrography Dataset in geodatabase format. Mean flow volume and velocity attributes are linked to the NHD flowlines. USGS real-time stream flow gages are also being indexed to NHD so that travel time and concentration is based on flow conditions at the time of the spill event. This model forms the basis of the transport module of the Incident Command Tool for Protecting Drinking Water (ICWater). Public water supply intakes, HazMat sites, dams, pipelines, bridges, and railroads are also included as part of ICWater. Both stand-alone and web-based versions are being developed.
