Modelled fluvial flood depth data with climate change created 2004: 1 percent annual chance for grid reference SJ

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.

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 SJ. 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.

本模型化的河流洪水深度数据，系针对1%年一遇的洪水情况编制，并作为2004年广义建模项目的副产品生成。广义建模项目的宗旨在于填补2004年未详尽的地方模型化数据之空白，以界定防洪区的范围，为空间规划提供依据。

此气候变化数据旨在提供基于河流模型中峰值流量增加20%的气候变化可能影响的初步敏感性分析。

采用名为JFlow的二维水动力学模型，在5x5米的网格上生成了此模型化的河流洪水深度数据。

自2004年以来，一些地方详细建模项目已包含气候变化情景，然而此气候变化数据集尚未更新。

信息警告：本数据不适用于判断单个财产是否会因气候变化而洪水，亦不适用于详细决策或特定地点的防洪风险或战略防洪风险评估。在使用本数据时，应进行进一步证据收集、验证和研究。自2004年工作完成后，气候变化预留值已发生变化。

对于某些地区，可获取更近、更准确且更详细的本地模型化深度数据。如需了解您感兴趣区域是否可获得详细建模数据，请联系当地环境局办公室。

此元数据记录为批准访问产品AfA480 2004气候变化1：100河流洪水深度网格。

模型化的河流洪水深度数据（含气候变化）适用于整个英格兰，但此数据仅针对100x100平方公里的军械调查国家网格参考SJ。如需其他网格参考数据，请参阅此军械调查国家网格文档以查找相关引用代码，并在Data.gov.uk上再次搜索以下载数据。归属声明：© 环境局版权和/或数据库权利2016。版权所有。本信息中的一些特性基于从生态水文中心（CEH）许可的数字空间数据。© NERC（NERC）。Defra、气象办公室和DARD河流管理局©皇家版权。© 克兰菲尔德大学。©詹姆斯·哈顿研究所。包含OS数据©皇家版权和数据库权利2015。土地与财产服务©皇家版权和数据库权利。
