Over the past decade, terrorism risk has become a prominent consideration in protecting the well‐being of individuals and organizations. More recently, there has been interest in not only quantifying terrorism risk, but also placing it in the context of an all‐hazards environment in which consideration is given to accidents and natural hazards, as well as intentional acts. This article discusses the development of a regional terrorism risk assessment model designed for this purpose. The approach taken is to model terrorism risk as a dependent variable, expressed in expected annual monetary terms, as a function of attributes of population concentration and critical infrastructure. This allows for an assessment of regional terrorism risk in and of itself, as well as in relation to man‐made accident and natural hazard risks, so that mitigation resources can be allocated in an effective manner. The adopted methodology incorporates elements of two terrorism risk modeling approaches (event‐based models and risk indicators), producing results that can be utilized at various jurisdictional levels. The validity, strengths, and limitations of the model are discussed in the context of a case study application within the United States.

PurposeThe purpose of this paper is to assess the issues faced by managers of inland waterways in the Southeastern USA as a guide for improvements to spill management information systems.Design/methodology/approachA survey was administered to a group of over 300 professionals representing multiple organizations involved in water quality management and/or spill response in the Southeast region of the USA to query their perceptions on leading demands and issues faced in management of inland waterways both on a daily basis and during spill response efforts.FindingsSurvey results indicated that communication is often the "weak link" in both water management and spill response activities, and that enhanced spill management information tools could serve as a valuable resource in addressing this problem. Display of spatial/visual information was deemed to be especially important to spill response personnel and should be included in the next generation of spill response systems.Research limitations/implicationsThe scope is limited to the Southeastern USA, but similar results would be expected in other regions where management of surface water is of concern.Practical implicationsIn these trying economic times, the survey results serve to rank order decision‐support priorities to which available resources should be allocated and indicate areas of interest for improved support in both water resource management and spill response.Originality/valueThe paper provides the first documentation of the demands and decision‐support priorities of inland waterway resource managers and spill response personnel.
