Digital Infrastructures addresses how information technologies can be used to manage water, power, transport, and telecommunication systems.  The book balances analyses of specific civil and environmental systems with broader treatments of social, organizational, management and environmental forces that impact these critical infrastructures.   The book is organized into four sections. First, fundamental themes of policy, management, and technology are presented to frame the domain of digital infrastructures. Second, the way in which information technologies are applied in specific infrastructure sectors (including water, power, transport, and telecom) are reviewed with a focus on critical technological, managerial, and policy issues confronting system planners and managers. Third, cross-cutting themes of economics, earth systems engineering, and international sustainability are examined as alternative systems perspectives for achieving the integration of information technology and infrastructure. Finally, the concluding section considers  new directions and challenges being posed by issues such as crises management and homeland security.  Additional information about the book, editors, contributors and ordering is provided below.
