Ocean Hazards Database (OHD) for the State of Hawaii Statewide Coastal Highway Program Report

Summary:

This Ocean Hazards Database (OHD) contains all relevant geographic information system (GIS) layers, maps, measures, interpretations, and rankings from the Ocean Hazards Classification Scheme (OHCS) assessment of 302 mileposts and points of interest across coastal state routes in Hawaii. As a part of the State of Hawaii Department of Transportation Statewide Highway Shoreline Program Report, the OHCS assesses and ranks shoreline roadway vulnerability to historical sea-level rise rates (in/yr), projected sea-level rise rates by 2050 and 2100 (in/yr), mean tidal ranges (ft), maximum annually recurring peak wave periods (sec) and significant wave heights (ft), mean projected shoreline change rates (ft/yr) and coastal armoring, historical and hypothetical tsunami flow depths (ft), and hypothetical category 1-4 storm surge inundation heights (ft). OHCS ranking criteria and methods are described in Chapter 3 of the State of Hawaii Statewide Coastal Highway Program Report (2019). OHD materials are organized into coastal highway digital elevation models, ocean hazard map packages, ocean hazard supplementary maps, and ocean hazard supplementary tables.

摘要：

本海洋灾害数据库（OHD）包含夏威夷沿海州级公路沿线302个里程桩及兴趣点的海洋灾害分类体系（OHCS）评估中所有相关的地理信息系统（GIS）图层、地图、测量数据、解释及排名。作为夏威夷州交通部《全州公路海岸线项目报告》的一部分，OHCS针对海岸线公路的脆弱性进行评估与排名，评估指标包括历史海平面上升速率（英寸/年）、2050年及2100年预测海平面上升速率（英寸/年）、平均潮差（英尺）、年度最大重现峰值波周期（秒）、有效波高（英尺）、平均预测海岸线变化速率（英尺/年）、海岸防护工程、历史及假设海啸流深（英尺），以及假设1-4级风暴潮淹没高度（英尺）。OHCS的排名标准与方法详见《夏威夷州全州沿海公路项目报告（2019）》第3章。OHD的资料分为沿海公路数字高程模型、海洋灾害地图包、海洋灾害补充地图及海洋灾害补充表格四类。
