Description
Abstract: This research presents a quantitative resource model that embeds input-output relationships of supply and demand within a spatial network model. This allows the impacts of a spatial hazard on the movement of resources to be evaluated. The model enables scenarios and interventions to be explored to aid the development and design of effective infrastructure provision to sustain the resource needs of a modern society. The model has initially been tested on a case study in the Shetland Islands. The analysis highlights how a single flood event can disrupt the movement of resources across the region. Disruption of certain sectors can lead to a cascading failure across the system, which result from system interdependencies. Resource management strategies, such as storing supplies locally or alternative movement schedules are shown to increase the resilience of the system. Finally, planned model and case study developments are described.
