As there has been a continued increase in the demand for higher levels of safety, security and reliability for all critical infrastructures, the design, construction, and operation of dams should be integrated as part of a comprehensive risk management framework that can effectively address natural and manmade hazards. As an effect, in recent years integrated management strategies have become more and more important, and as such, their related implementation efforts should include aspects such as sustainability, resilience, and public participation. Risk Analysis, Dam Safety, Dam Security, and Critical Infrastructure Management offers the state of the art on risk analysis, representing a primary tool for achieving effective management of critical infrastructures along with a suitable framework for the development of risk management models regarding natural, technological and human-induced hazards. The book is divided in four parts: Critical Infrastructure Management, focusing on efficient, equitable, and sustainable management of critical infrastructures; Risk Analysis, focusing on recent developments regarding risk management models for natural, technological and human-induced hazards; Dam Safety, focusing on recent developments regarding dam safety, and Dam Security, focusing on aspects regarding dam security and vulnerabilities to human-induced threats. This book is essential reading for graduate students and researchers interested in risk analysis as applied to all type of critical infrastructures, and for designers, engineers, owners and operators of critical infrastructures in general and dams in particular.

Abstract. Dams as well as protective dikes and levees are critical infrastructures whose associated risk must be properly managed in a continuous and updated process. Usually, dam safety management has been carried out assuming stationary climatic and non-climatic conditions. However, the projected alterations due to climate change are likely to affect different factors driving dam risk. Although some reference institutions develop guidance for including climate change in their decision support strategies, related information is still vast and scattered and its application to specific analyses such as dam safety assessments remains a challenge. This article presents a comprehensive and multidisciplinary review of the impacts of climate change that could affect dam safety. The global effect can be assessed through the integration of the various projected effects acting on each aspect of the risk, from the input hydrology to the calculation of the consequences of the flood wave on population and assets at risk. This will provide useful information for dam owners and dam safety practitioners in their decision-making process.

In the past few years, the field of dam safety has approached risk informed methodologies throughout the world and several methodologies and programs are appearing to aid in the systematization of the calculations. The most common way of implementing these calculations is through the use of event trees, computing event probabilities, and incremental consequences. This methodology is flexible enough for several situations, but its generalization to the case of systems of several dams is complex and its implementation in a completely general calculation methodology presents some problems. Retaining the event tree framework, a new methodology is proposed to calculate incremental risks. The main advantage of this proposed methodology is the ease with which it can be applied to systems of several dams: with a single risk model that describes the complete system and with a single calculation the incremental risks of the system can be obtained, being able to allocate the risk of each dam and of each failure mode. The article shows how both methodologies are equivalent and also applies them to a case study.
