The loss of inland waterway infrastructure assets could have severe adverse societal and economic effects areas directly impacted, the surrounding regions and/or the nation. The Supporting Secure and Resilient Inland Waterways (SSRIW) project is being undertaken in close collaboration with our sister NTSCOE, the Mack-Blackwell Rural Transportation Center at the University of Arkansas. The goal of the SSRIW project is to develop a prototype decision support system that integrates state-of the-art geographic information system (GIS) technology and computer-based vulnerability and risk assessment models to provide timely knowledge and awareness of what infrastructure exhibits high risk and low resiliency to potential attacks or natural disasters against critical inland waterway transportation systems.
