FutureCoast Erosion Polygons (2050) for High Emissions Scenario SLR

Anticipated erosional areas, between the current 2020 and anticipated 2050 Mean High Water Spring tide lines, based on a High Emissions Scenario sea level rise projection (RCP8.5, 95 percentile) and 'do nothing' coastal management approach. Shoreline retreat is limited by underlying physical susceptibility model (the UPSM of Fitton et al., 2017) and up to 25m of erosion is premitted at known artificial coastal defences. Dataset includes Erosion Area (areas seawards of the 2050 projected position of Mean High Water Springs), Erosion Influence (a 10m landward buffer of the projected position of 2050 MHWS) and Erosion Vicinity (a further 50m landward buffer on Erosion Influence). This data contains the intersect values for society's assets (lengths of roads (km), areas of designates sites (ha)). Further explanation available within Technical Summary WS2, via www.DynamicCoast.com/reports.
Please note, there are two versions of this data, one 'Full' version, for Public Sector organisations in support of statutory work. This dataset includes the number of residential and non-residential properties affected within each erosion polygon, alongside other asset types. The 'public' version exlcudes these two fields.

预期侵蚀区域，介于当前2020年与预测2050年平均高潮春潮线之间，基于高排放情景下的海平面上升预测（RCP8.5，95百分位数）及‘不采取行动’的海岸管理策略。海岸线退缩受限于基础物理敏感性模型（Fitton等人，2017年的UPSM模型）以及已知的人工海岸防御设施允许的最大25米侵蚀。数据集包含侵蚀区域（2050年预测的平均高潮春潮线 seawards 之外的区域）、侵蚀影响区（2050年预测的平均高潮春潮线位置向内陆10米的缓冲区）和侵蚀邻近区（侵蚀影响区再向内陆50米的缓冲区）。此数据集包含了社会资产（道路长度（公里）、指定场地面积（公顷））的交叠值。更多解释可参见技术摘要WS2，详情请访问www.DynamicCoast.com/reports。请注意，此数据集存在两个版本，一为‘完整’版本，适用于公共部门机构以支持法定工作。该数据集包括每个侵蚀多边形内受影响的住宅和非住宅物业数量，以及其他资产类型。‘公共’版本则不包括这两个字段。
