Modelled fluvial flood depth data with climate change created 2004: 1 percent annual chance for grid reference TR
收藏资源简介:
This modelled fluvial flood depth data with climate change was created for the 1% annual chance of flooding situations and was produced as a by-product from the 2004 generalised modelling project. The purpose of the generalised modelling project was to fill the gaps where there was no detailed local modelled data in 2004, in order to define the extents of Flood Zones for spatial planning. The purpose of this climate change data was to provide a high-level sensitivity analysis of the possible effects of climate change based on a 20% increase in peak flows in the fluvial modelling. A two-dimensional hydrodynamic model called JFlow was used to produce this modelled fluvial flood depth data on a 5x5m grid. Since 2004, some local detailed modelling projects have included scenarios for climate change however this climate change dataset has not been updated. INFORMATION WARNING: This data is not suitable for identifying whether an individual property will flood due to climate change, for detailed decision making or for use in site specific Flood Risk or Strategic Flood Risk Assessments. Where this data is used further evidence, verification and studies should be undertaken. Climate change allowances have changed since this work was completed in 2004. More recent, accurate and local detailed modelling depth data with climate change is available for some places. Please contact your local Environment Agency office to see if detailed modelling is available for your area of interest. This metadata record is for Approval for Access product AfA480 2004 Climate Change 1 in 100 Fluvial Flood Depth Grids Modelled fluvial flood depth data with climate change are available for the whole of England, however this data is for the 100x100km squared Ordnance Survey National Grid reference TR. If you are interested in data for another grid reference refer to this Ordnance Survey National Grid document to find the relevant referencing code and search on Data.gov.uk again to download the data.

本附带气候变化情景的河流洪水水深(fluvial flood depth)模拟数据,是为应对年超越概率1%的洪水情景而生成,其作为2004年通用建模项目(generalised modelling project)的副产品产出。该通用建模项目的初衷,是填补2004年当地缺乏详细本地化模拟数据的空白,以明确洪水分区(Flood Zones)范围,服务于空间规划工作。 本气候变化数据集的研制目标,是基于河流洪水模拟中洪峰流量(peak flows)增加20%的情景,开展气候变化潜在影响的高层次敏感性分析。 本次数据采用二维水动力模型(two-dimensional hydrodynamic model)JFlow,在5米×5米的网格(grid)上生成河流洪水水深模拟结果。 自2004年起,部分本地详细建模项目已纳入气候变化情景,但本气候变化数据集尚未进行更新。 【数据使用警示】:本数据不适用于识别单个物业是否会因气候变化遭受洪水侵袭,也不适合用于精细化决策、场地特定洪水风险评估或战略洪水风险评估。若使用本数据,需开展额外的论证、验证与研究工作。自2004年本项目完成以来,气候变化适配标准已发生变更。 部分地区已获取更新、更精准且包含气候变化情景的本地详细洪水水深模拟数据。您可联系当地环境署(Environment Agency)办事处,查询目标区域是否有此类详细建模数据。 本元数据(metadata)记录对应获批访问产品AfA480——《2004年气候变化情景下百年一遇河流洪水水深网格数据》。 本附带气候变化情景的河流洪水水深模拟数据覆盖英格兰全境,但本数据集对应英国地形测量局(Ordnance Survey)国家网格参考系中100km×100km的TR区块。若您需要其他网格参考系的数据,请查阅该英国地形测量局国家网格文档获取对应参考代码,随后前往Data.gov.uk平台再次检索下载所需数据。 版权声明:© 环境署(Environment Agency)版权及数据库权益2016年。保留所有权利。本信息的部分内容基于由生态与水文学中心(Centre for Ecology & Hydrology, CEH)授权的数字空间数据,© 英国自然环境研究理事会(NERC)。英国环境、食品与农村事务部(Defra)、英国气象局(Met Office)及北爱尔兰农业、环境与乡村事务部河流管理局© 王室版权。© 克兰菲尔德大学(Cranfield University)。© 詹姆斯·赫顿研究所(James Hutton Institute)。本数据包含英国地形测量局数据,© 王室版权及数据库权益2015年。土地与物业服务处© 王室版权及数据库权益。
