Threat Ensemble Vulnerability Assessment - Sensor Placement Optimization Tool (TEVA-SPOT) Graphical User Interface User's Manual [open pdf - 6MB]
"Under existing laws and recent Homeland Security Presidential Directives, EPA has been called upon to play a vital role in helping to secure the nation against foreign and domestic enemies. The National Homeland Security Research Center (NHSRC) was formed in 2002 to conduct research in support of EPA's role in homeland security. NHSRC research efforts focus on five areas: water infrastructure protection, threat and consequence assessment, decontamination and consequence management, response capability enhancement, and homeland security technology testing and evaluation. […] Threat Ensemble Vulnerability Assessment -- Sensor Placement Optimization Tool (TEVA-SPOT) allows users to define a water network contamination 'scenario,' simulate the spread of the contaminant or contaminants throughout the water network, analyze the consequences, and display the results in a variety of graphical and tabular forms. The ultimate aim of a simulation and its subsequent analysis is to determine the vulnerability of the distribution system to contaminant releases and determine the optimal locations to place a set of water quality sensors in the network to mitigate the impacts of contamination. This Users Manual helps to familiarize users with the TEVA-SPOT Graphical User Interface (GUI) functionality. TEVA-SPOT assumes ones familiarity and use with EPANET. Users should first be sure their network model runs in EPANET prior to running the model in TEVA-SPOT."
