Hydromorphological attributes for all Australian river reaches

Hydromorphological data including temporal and spatial river width dynamics, flow regime, and river gradient for 1.4 million Australian river reaches are presented. This river hydromorphology dataset is developed based on surface water recurrence information from the WOfS Landsat-derived dynamic water mapping product and GIS-based hydrological features from the Australian Geofabric. We also propose a parameter which can be used to classify reaches by the degree to which flow regime tends towards permanent, frequent, intermittent, or ephemeral. This dataset provides fundamental information for understanding hydrological, biogeochemical, and ecological processes in floodplain–river systems; describing river width features in hydrological modelling; estimating river depth and discharge; assessing river conveyance capacity; identifying flooding-prone areas, and determining potential locations for satellite-based river gauging.
