Infrastructure Risk Management Processes: Natural, Accidental, and Deliberate Hazards, discusses quantification of exposure and vulnerability of complex, spatially distributed systems, yielding estimates of local and system-wide potential losses, for different alternatives in multi-hazard decision situations. These situations require an integration of scientific, engineering, social, administrative, psychological, and political processes with advances, setbacks, and many uncertainties. This monograph consists of eight papers that illustrate work done to date and plans for work to be done on managing these risks for potable water, electric power, transportation and other infrastructure systems threatened by earthquakes, tsunamis, landslides, severe storms, saboteurs, and various other hazards. This monograph, produced by the Risk and Vulnerability Committee of the Council on Disaster Risk Management (CDRM), is a sequel to a previous monograph, ""Acceptable Risk Processes: Lifelines and Natural Hazards"" (2002), published by ASCE. Topics covered include: Hazard Issues; Systems Evaluation Issues; Risk Criteria Issues; and Systems Management Issues.
