Hydrodynamic model of the Cooper Creek floodplain

\n## **Abstract** \nThis dataset was compiled by the Geological and Bioregional Assessment Program from source data referenced within the dataset and/or metadata. NOTE: LARGE FILE SIZE ~235 GB. The dataset contains the model files, inputs and outputs for the hydrodynamic model of the Cooper Creek floodplain. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement. The Cooper GBA region has a large floodplain that floods frequently. This dataset contains model setups and validation results of a 2D hydrodynamic model (MIKE21FM), and all inputs and outputs for selected historical flood events (one set each for the Queensland side and South Australian side of the Cooper Creek). The calibrated hydrodynamic model can be used to evaluate how flood characteristics may change under future scenarios (development and future climate change). Outputs from the hydrodynamic modelling include 6 hourly estimates of spatial flood extents across the modelling domain, and water depth and velocities for each mesh element for all the historical flood events used. The full details about the modelling (model setups, inputs and outputs) are described in details in the Cooper flood modelling report. This is a large dataset and may take several hours to several days to download depending on internet connection speed.\n\n\n## **Attribution** \nGeological and Bioregional Assessment Program\n\n\n## **History** \nThe model setup includes model mesh and all related setup files, inputs include rainfall, potential evapotranspiration, LiDAR DEM, river and water holes bathymetry, classified Landsat images for the flood events used, soil characteristics, vegetation characteristics, observed streamflow at the upstream gauges and ungauged inflows along the model domain boundaries estimated using a regionally calibrated rainfall-runoff model.\r\nThe methods report without accompanying data is available from the CSIRO Research Publications Repository.

## **摘要**
本数据集由地质与生物区域评估计划（Geological and Bioregional Assessment Program）基于数据集内及/或元数据中引用的源数据编制而成。注意：文件体量较大，约235 GB。本数据集包含库珀河漫滩水动力模型的模型文件、输入与输出数据。本衍生数据集的生成流程详见本元数据说明的“历史沿革”字段。
库珀GBA区域拥有大片漫滩，洪涝灾害频发。本数据集包含二维水动力模型（MIKE21FM）的模型搭建方案与验证结果，以及库珀河昆士兰州段与南澳大利亚州段各一组选定历史洪水事件的全部输入与输出数据。
经率定的水动力模型可用于评估未来情景（包括开发活动与气候变化）下洪水特征的变化情况。本次水动力模拟的输出结果包括：模拟全域内每6小时一次的空间洪水范围估算数据，以及所用全部历史洪水事件中每个网格单元的水深与流速数据。有关本次模拟的全部细节（模型搭建方案、输入与输出数据）均详见《库珀河洪水模拟报告》。本数据集体量较大，根据网络连接速度的不同，下载可能需要数小时至数天不等。
