Abstract: This paper describes a web-based, fully-automated, two-dimensional dam-break flood simulation and mapping system for the entire USA, which was developed by integrating the numerical solver DSS-WISE™Lite with the DSAT (Dams Sector Analysis Tool) web-based platform. DSAT/DSS-WISE™ Lite capability is the result of a joint effort between the University of Mississippi National Center for Computational Hydroscience and Engineering (UM-NCCHE) ,the Dams Sector-Specific Agency of the Office of Infrastructure Protection at the Department of Homeland Security (DHS) National Protection and Programs Directorate (NPPD) ,the U. S. Army Corps of Engineers (USACE) ,and Argonne National Laboratory (ANL) . DSS-WISE™Lite is a state-of-the-art, two-dimensional flood simulation software derived from DSS-WISE™ (Decision Support System for Water Infrastructural Security) software, which is an integrated system for dam/levee break/breach flood simulation, mapping and GIS-based consequence analysis software. DSS-WISE™was developed by the UMNCCHE within the framework of SERRI (South East Region Research Initiative) Program, funded by the Department of Homeland Security (DHS) Science and Technology Directorate (S& T) and monitored by Oak Ridge National Laboratory (ORNL) .DSAT is a web-based tool jointly developed by DHS and USACE in order to provide a wide range of analytical capabilities for owners and operators of public and private dams. It resides on a server hosted by ANL provides access to various analytical tools, including DSS-WISE™ Lite. The system is fully automated and operates without human intervention. It is available 24/7 and free of charge to authorized users. The statistics show that for 91%of simulations with30m cell size and 81%of simulations with 10m cell size the results are sent to the user within one hour. The DSAT/DSSWISE™Lite system has been in operation for 34 months and handles on the average 4 to 5 simulations per day. Because of its excellent computational performance, DSAT/DSS-WISE™Lite serves not only as a tool for screening and prioritizing dams but also as a real-time operational tool for emergency management. It was has already been used as a decision making and emergency planning tool by dam safety engineers, flood emergency managers and decision makers.
