An innovative technique for modelling impacts of coastal storm damage

摘要

A spatial–temporal model is developed to model the impacts of simulated coastal region storm surge and flooding using a combined spatial mapping and system dynamics approach. By coupling geographic information systems and system dynamics, the interconnecting components of the spatial–temporal model are used with historical data to evaluate storm damage. The model examines the component-wise changes to the physical environment, community infrastructure and socioeconomic resources from simulated storm surges. To illustrate this model, the research is applied to the case of Charlottetown on Prince Edward Island, Canada, a vulnerable coastal city subject to considerable impacts from increasingly frequent severe storm surges.
