IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Web-based, automated dam-break flood simulation and mapping system for the usa

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 with
30m 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.
