An oil risk management system based on high-resolution hazard and vulnerability calculations

摘要

A new oil risk management system is proposed herein. Risk is computed in a quantitative way, combining a detailed hazard maps generated with a process-based oil spill model over an unstructured computational grid, and a spatially detailed methodology for vulnerability analysis. The system has a web interface that serves as a single point of access to both emergency-driven and risk-management products. The system's products are made available to decision makers and emergency response agents through a WebGIS portal. The paper describes the methodological bases and application of a risk assessment tool that provides hazard, vulnerability and risk assessment maps for oil spills in coastal areas.
