Development of a method for studying cascading effects between critical infrastructures

Abstract: Most current methods for studying cascading effects rely on written sources to extract information. This thesis presents an empirical method for studying cascading effects, when little written information of the event is available. The method presented has been influenced by incident investigation methods. It has been applied on a case of flooding in south of Sweden and revised based on the results. The case study showed that the method is able to gather and structure information about cascading effects and conditions that affect the outcome of cascading effects. An advantage of this method is that it captures conditions as well as potential cascading effects.
