Integration of oil spill modeling with coastal resource information could be useful for protecting the coastal environment from oil spills. A scenario-based risk assessment and sensitivity indexing were performed for the Chennai coast by integrating a coastal resource information system and an oil spill trajectory model. The fate analysis of spilled oil showed that 55% of oil out of a total volume of 100m(3) remained in the water column, affecting 800m of the shoreline. The seasonal scenarios show major impact during the southwest (SW) and northeast (NE) monsoons and more fatal effects on marine pelagic organisms during SW monsoon. The Oil Spill Risk Assessment Modeler tool was constructed in a geographic information systems (GIS) platform to analyze the risks, sensitivity mapping, and priority indexing of resources that are likely to be affected by oil spills along the Chennai coast. The results of sensitivity mapping and the risk assessment results can help organizations take measures to combat oil spills in a timely manner.
将溢油模型与沿海资源信息相结合，对于保护沿海环境免受溢油影响可能是有用的。通过整合沿海资源信息系统和溢油轨迹模型，对钦奈海岸进行了基于情景的风险评估和敏感性指数分析。溢油命运分析表明，100m³ 总溢油量的 55% 仍留在水柱中，影响了 800m 的海岸线。季节情景表明，西南季风和东北季风期间影响较大，西南季风期间对海洋浮游生物的危害更大。溢油风险评估模型工具构建在地理信息系统 (GIS) 平台上，用于分析钦奈海岸沿线可能受到溢油影响的资源的风险、敏感性映射和优先级索引。敏感性映射和风险评估结果可以帮助组织及时采取措施应对溢油。
