Flood inundation maps (climate scenarios) for the Fitzroy catchment in Western Australia

Flood inundation maps for the Fitzroy catchment in Western Australia for the baseline, dry and wet climate scenarios\nLineage: These data were generated from hydrodynamic modelling (MIKE21 model) results. These are grid based (30m x 30m) inundation depth at 6-hourly time interval. Flood events were simulated for 40 days irrespective of their magnitude to ensure complete recession of each flood. Model outputs were processed in ArcGIS. Inundation extent and duration were estimated by accumulating six hourly model outputs for the simulation period of 40 days. The data represent number of days each computational grid was inundated during the entire simulation period.

澳大利亚西澳大利亚州菲茨罗伊流域（Fitzroy catchment）适配基准、干旱与湿润三种气候情景的洪水淹没地图数据集。数据溯源：本数据集基于水动力模型（MIKE21 model）的模拟结果生成。数据采用30米×30米的格网格式，存储每6小时时间步长的淹没水深。为确保每场洪水完全退水，本次模拟对所有洪水事件开展了为期40天的全周期模拟，未考虑洪水的实际规模。模型输出结果通过ArcGIS软件进行处理；通过累加40天模拟周期内的每6小时模型输出结果，可估算得到淹没范围与淹没时长。本数据集记录了整个模拟周期内，每个计算格网被淹没的总天数。
