This dataset is an updated version of the Two-Monthly Maximum Flood Water Depth Spatial Time Series for the Murray-Darling Basin (MDB) (https://doi.org/10.25919/c5ab-h019). It provides two-monthly spatial layers representing the maximum surface water extent and water depth within each two-month period across the MDB from 1988 to 2024. The dataset was developed using the Multi-Index Method (MIM) for surface water mapping (https://data.csiro.au/collection/csiro:63899, please refer to the metadata of this dataset for details) and a Digital Elevation Model (DEM) (https://data.csiro.au/collection/csiro:64136) processed with the Floodwater Depth Estimation Tool (FwDET). Key improvements in this version include: • Coverage updated to June 2024. • Enhanced water detection in wetlands and vegetated areas using remote sensing imagery. • Improved cloud masking algorithms. • More accurate water depth estimation through the use of a bathymetry-enforced DEM. This updated dataset offers 36.5 years of two-monthly images of surface water depth across the entire MDB. The file format is Cloud Optimised Geotiff (COG). The data type for the files is uint16. The unit of the data is in millimetres. The maximum depth is 65534mm; minimum water depth is 1mm; value 0 represents dry land; and value 65535 represents no-data. The file format is Cloud Optimised Geotiff (COG) and the projection used is EPSG:4326.
