  • PUBLICATION NOTICE: Water Security Scenarios: Planning for Installation Water Disruptions

    Abstract: The Army’s critical missions are at risk from interruption of water supplies. Sufficient amounts of high- quality potable water are a resource without substitute. The Army’s Installation Energy and Water Security Policy establishes requirements for installations to sustain critical mission capabilities and to mitigate risks posed by energy and water disruptions that affect installations; this includes coordinating vulnerability and risk assessments of potential disruptions and implementing adequate responses to mitigate identified risks. Resilient installations will develop storage capacity to forestall water shortages and will also have short- and long-term plans to help the installation recover from events and forestall progressing to more severe deficits. This project supports compliance with the water security policy by exploring the range of conditions and responses possible across installations. Multiple scenarios were developed to explore how a 14-day interruption in water supply might affect an installation and to provide preliminary guidance to help installations develop strategies to address water disruptions to critical missions drawing from existing processes used in mission assurance. Researchers investigated types of installations and classes of scenarios most relevant to installation water security planning and explored several scenarios to provide a framework to helps installations advance their water resilience and security planning.
  • PUBLICATION NOTICE: Operation and Deployment Risk Assessment Report for the City of Cedar Rapids, Iowa: Alternative and Sequencing Optimization for Removable Flood Barriers

    ABSTRACT: The City of Cedar Rapids, Iowa, partnered with engineering firms and the US Army Engineer District, Rock Island (MVR), to develop a Flood Control System (FCS). In 2011, the US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory (ERDC-CHL), was tasked with completing a risk assessment of removable floodwalls on the eastern side of the Cedar River. In 2016, ERDC-CHL was asked to include the temporary flood closure barriers on both sides of the Cedar River. Phase 1 of the study consisted of seven alternatives to be considered for the final FCS design, with a goal of a 90% confidence of successful deployment. Phase 2, initiated by MVR, targeted a 95% confidence level. The method used for evaluation was RiskyProject® software. The software used a Monte Carlo method of analysis to determine a range of durations, manpower, and labor costs based on logical sequencing. The results showed that the “Master Plan Minus 400 ft” alternative to be the most efficient for Phase 1. The most efficient alternative for Phase 2 was Task 5.4, which achieved a 95% confidence level of completion within 48 hours. The Phase 1 and the Phase 2 descriptions are detailed within this report.
