We are using satellite imagery to map floodplain inundation in the Northern Murray Darling Basin, and where satellite imagery is not available due to issues such as cloud cover, we will use predictive modelling techniques. This work will help us to identify the effect of floodplain structures on flood pathways, validate environmental water requirements and link ecosystem health with inundation patterns.
Our projects include:
- Mapping and modelling floodplain inundation
- Validating overbank environmental water requirements
- Identification and mapping of flood paths and floodplain connectivity
- Assessing the impact of floodplain structures on flood paths
In 2021-22, the flood inundation mapping project has:
- Assessed the suitability of a number of datasets, water indices and thresholds for mapping inundation extent across the northern Murray-Darling basin.
- Produced over 400 maps of inundation extent for each catchment in the northern Murray-Darling basin. These maps closely represent the extent of field-observed inundation.
- Undertaken a case study within the Border Rivers catchment.
