Flood inundation extent and duration for the Fitzroy catchment in Western Australia

Brief description

This dataset provides flood inundation extent and duration for the Fitzroy catchment in Western Australia for the flood events of 2001, 2002, 2006, 2007, 2009, 2011 and 2014. The data are in raster format. The values in the raster file shows the duration of inundation (days) during an event. The following are the start and end time for each flood.

Lineage: These data were generated from hydrodynamic modelling (MIKE21 model) results. Model outputs were processed in ArcGIS. Inundation extent/ duration was estimated by accumulating six hourly model outputs for the simulation period of 40 days. The data represent number of days each computational grid (30m x 30m) was inundated during the entire simulation period.
