Available in PDF, EPUB and Kindle. Book excerpt: Water distribution systems are vital to the well-being of communities because they contribute to the functionality of all other infrastructure and lifeline systems. Earthquakes and other natural hazards can cause damage to the components of a water distribution system, causing far-reaching socioeconomic consequences. This research begins with the development of an end-to-end simulation framework to model post-earthquake functional loss and restoration of a water system, which encompasses seismic hazard characterization, component damage assessment, hydraulic performance evaluation, and network restoration modeling. The modeling framework is validated using data from the 2014 South Napa Earthquake and extended to a hypothetical scenario. The end-to-end simulation framework is then extended to consider stochastic event set assessments of the water network using the UCERF2 (Uniform California Earthquake Rupture Forecast, Version 2) earthquake rupture forecast model. Given that the end-to-end performance evaluation of distributed infrastructure for a large set of events is computationally expensive, a framework that uses Active learning to select a subset of ground motion maps and associated occurrence rates that reasonably estimates the water network risk is also developed. To deal with the temporal complexities that are embedded in the post-earthquake restoration process, a dynamic updating methodology is developed to reduce uncertainties in the outcomes of post-event recovery forecasts using Bayesian Inferencing, by exploiting real-time data. The specific example of updating predictions (post-earthquake functional recovery forecasts including total recovery time and complete recovery trajectory) is presented and validated on a real pipe network (Napa water system) and event (2014 earthquake and recovery). Ultimately, the frameworks and models developed as part of this work can inform risk-based decision making and resilience planning of water networks and other lifeline systems.

Download or read book Risk Based Asset Management Framework for Water Distribution Systems written by Ram Krishna Mazumder and published by . This book was released on 2020 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Distribution Systems (WDSs) are the most essential civil infrastructure systems for the functioning of communities. Economic prosperity and social wellbeing of modern society depend on reliable, robust, and resilient WDSs. Unfortunately, a majority of water pipelines in the United States (U.S.) are in service beyond their intended design life and have experienced a high failure rate. Aged metallic pipelines are susceptible to failure due to corrosion deterioration, traffic loading, excessive water pressure, seismic loading, and other factors. These failures result in enormous direct and indirect economic and societal consequences. Moreover, water pipe failures often lead to cascading consequences to other interconnecting infrastructure, especially road networks. In the face of these frequent failures, water utilities are struggling to maintain their assets with limited budget and resource constraints. There is a clear need to develop a comprehensive framework to assess and mitigate the risk posed by combined external loading (e.g., water pressure, traffic loading, earthquakes) and corrosion deterioration to WDSs. This research presents a risk-based asset management decision-support framework for WDSs subjected to combined corrosion and external loading, considering both component-level and system-level risk. A critical literature review of existing literature on various aspects of asset management is performed to establish the knowledge gap between current practice and theory in WDS research. Various fragility models of pipelines and systems are developed considering the effect of corrosion deterioration. Uncertainties involved in fragility and restoration models are accounted for using the probabilistic approaches. The seismic restoration process is modeled considering the repair activities overtimes. Next, a framework is proposed that incorporates topological and hydraulic reliability model, seismic functionality and resilience model, scenario-based seismic damage and renewal cost analysis, post-disaster repair sequence model, and risk-based decision tools. The framework developed in this research is intended to support water utilities in long term asset management and investment decisions. Although this approach is presented for WDSs, the proposed asset management framework can be applied to other types of networked systems.

Download or read book National Earthquake Resilience written by National Research Council and published by National Academies Press. This book was released on 2011-09-09 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States will certainly be subject to damaging earthquakes in the future. Some of these earthquakes will occur in highly populated and vulnerable areas. Coping with moderate earthquakes is not a reliable indicator of preparedness for a major earthquake in a populated area. The recent, disastrous, magnitude-9 earthquake that struck northern Japan demonstrates the threat that earthquakes pose. Moreover, the cascading nature of impacts-the earthquake causing a tsunami, cutting electrical power supplies, and stopping the pumps needed to cool nuclear reactors-demonstrates the potential complexity of an earthquake disaster. Such compound disasters can strike any earthquake-prone populated area. National Earthquake Resilience presents a roadmap for increasing our national resilience to earthquakes. The National Earthquake Hazards Reduction Program (NEHRP) is the multi-agency program mandated by Congress to undertake activities to reduce the effects of future earthquakes in the United States. The National Institute of Standards and Technology (NIST)-the lead NEHRP agency-commissioned the National Research Council (NRC) to develop a roadmap for earthquake hazard and risk reduction in the United States that would be based on the goals and objectives for achieving national earthquake resilience described in the 2008 NEHRP Strategic Plan. National Earthquake Resilience does this by assessing the activities and costs that would be required for the nation to achieve earthquake resilience in 20 years. National Earthquake Resilience interprets resilience broadly to incorporate engineering/science (physical), social/economic (behavioral), and institutional (governing) dimensions. Resilience encompasses both pre-disaster preparedness activities and post-disaster response. In combination, these will enhance the robustness of communities in all earthquake-vulnerable regions of our nation so that they can function adequately following damaging earthquakes. While National Earthquake Resilience is written primarily for the NEHRP, it also speaks to a broader audience of policy makers, earth scientists, and emergency managers.

Download or read book Critical Infrastructures Resilience written by Auroop Ratan Ganguly and published by Routledge. This book was released on 2018-02-21 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text offers comprehensive and principled, yet practical, guidelines to critical infrastructures resilience. Extreme events and stresses, including those that may be unprecedented but are no longer surprising, have disproportionate effects on critical infrastructures and hence on communities, cities, and megaregions. Critical infrastructures include buildings and bridges, dams, levees, and sea walls, as well as power plants and chemical factories, besides lifeline networks such as multimodal transportation, power grids, communication, and water or wastewater. The growing interconnectedness of natural-built-human systems causes cascading infrastructure failures and necessitates simultaneous recovery. This text explores the new paradigm centered on the concept of resilience by approaching the challenges posed by globalization, climate change, and growing urbanization on critical infrastructures and key resources through the combination of policy and engineering perspectives. It identifies solutions that are scientifically credible, data driven, and sound in engineering principles while concurrently informed by and supportive of social and policy imperatives. Critical Infrastructures Resilience will be of interest to students of engineering and policy.

Available in PDF, EPUB and Kindle. Book excerpt: This book comprises components associated with smart water which aims at the exploitation and building of more sustainable and technological water networks towards the water–energy nexus and system efficiency. The implementation of modeling frameworks for measuring the performance based on a set of relevant indicators and data applications and model interfaces provides better support for decisions towards greater sustainability and more flexible and safer solutions. The hydraulic, management, and structural models represent the most effective and viable way to predict the behavior of the water networks under a wide range of conditions of demand and system failures. The knowledge of reliable parameters is crucial to develop approach models and, therefore, positive decisions in real time to be implemented in smart water systems. On the other hand, the models of operation in real-time optimization allow us to extend decisions to smart water systems in order to improve the efficiency of the water network and ensure more reliable and flexible operations, maximizing cost, environmental, and social savings associated with losses or failures. The data obtained in real time instantly update the network model towards digital water models, showing the characteristic parameters of pumps, valves, pressures, and flows, as well as hours of operation towards the lowest operating costs, in order to meet the requirement objectives for an efficient system.
