Flood Study — Citywide Overland Flow — Central Sub-Model

***This dataset is available on Brisbane City Council’s open data website – [data.brisbane.qld.gov.au](https://data.brisbane.qld.gov.au). The site provides additional features for viewing and interacting with the data and for downloading the data in various formats.*** \n \nBrisbane City Council Citywide Creek and Overland Flow Path Mapping Flood Study Central Sub\\-Model. This dataset contains reports, data and metadata used in the flood study, and results data for the existing floodplain condition scenarios. \n \nCouncil is committed to ensuring we have the latest flood modelling data to help manage flood risk in Brisbane. Flood studies provide Council with technical data to inform policy and for managing flooding within the Brisbane River and local creek and overland flow catchments. \n \nThe Citywide Creek and Overland Flow Path Mapping Flood Study comprises a series of 27 individual sub\\-models which cover the entire Brisbane City Council area. Results data for flood height, depth and hazard (depth x velocity) are available for each individual sub\\-model for the 2, 5, 10, 20, 50, 100, 500 and 2000 year Average Recurrence Interval (ARI) storm events. \n \nFor specific details on how the study was conducted, the areas it covers, and before using the data please read the flood study report. The flood study report, metadata used in the flood study and a detailed map that shows the 27 individual sub\\-models has also been made available in open data and is called [Flood Study — Citywide Overland Flow — reference](https://data.brisbane.qld.gov.au/explore/dataset/flood-study-citywide-overland-flow-reference). \n \nThe data on the table tab is the metadata relating to the data used for flood modelling in the Brisbane City Council Citywide Creek and Overland Flow Path Mapping Flood Study. \n \nMore information on flood studies and how this information is used can be found on the [Brisbane City Council Website](https://www.brisbane.qld.gov.au/community-safety/community-safety/disasters-emergencies/be-prepared/flooding-brisbane/flood-strategy/flood-studies). \nThe image below shows the 27 individual sub\\-models of the flood study and can be used to identify the sub\\-model for your location of interest.\n\n\n \n\n\n \n\n\n

布里斯班市议会全市溪流与地面流路径映射洪水研究中央子模型。本数据集包含洪水研究中使用的报告、数据和元数据，以及现有洪泛区条件情景下的结果数据。

市议会致力于确保掌握最新洪水建模数据，以助力布里斯班洪水风险的管理。洪水研究为市议会提供技术数据，用于指导政策制定及布里斯班河与本地溪流、地面流流域内的洪水管理。

全市溪流与地面流路径映射洪水研究包含27个独立子模型，覆盖布里斯班市议会辖区全域。针对2年、5年、10年、20年、50年、100年、500年及2000年平均重现期（Average Recurrence Interval，ARI）暴雨事件，每个子模型均提供洪水高度、深度及风险度（hazard，深度×流速）的结果数据。

关于研究的实施方法、覆盖区域及数据使用前的注意事项，请查阅洪水研究报告。洪水研究报告、研究中使用的元数据以及展示27个独立子模型的详细地图已在开放数据中发布，名称为《洪水研究——全市地面流——参考资料》[Flood Study — Citywide Overland Flow — reference](https://data.brisbane.qld.gov.au/explore/dataset/flood-study-citywide-overland-flow-reference)。

表格标签页中的数据是布里斯班市议会全市溪流与地面流路径映射洪水研究中用于洪水建模的数据相关元数据。
