NHD, RIVERSPILL, AND THE DEVELOPMENT OF THE INCIDENT COMMAND TOOL FOR DRINKING WATER PROTECTION

摘要

The RiverSpill time-of-travel spill model has been updated to use the NHD in geodatabase format. Mean flow volume and velocity attributes are linked to the NHD flowlines. USGS real time stream flow gages have been 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 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 have been developed.
