Using Australian water tools to develop new drought metrics for Cambodia
eWater, Geoscience Australia (GA) and the Australian Bureau of Meteorology (BOM) collaborated to pilot using space-based data to forecast streamflows and water availability.
With the support of the Australian Water Partnership, eWater, GA and the BOM worked with the United Nations Economic and Social Commission for the Asia Pacific (UNESCAP) to develop new metric’s for the their ‘Regional Cooperative Mechanism for Drought Monitoring and Early Warning in Asia and the Pacific’ (the Regional Drought Mechanism)
The project integrated three leading Australian tools for water management:
- Australia’s National Hydrology Modelling Platform – eWater Source
- GA’s Open Data Cube for accessing and managing space-based data
- the BOM’s streamflow forecasting tools
The pilot project integrated the three tools, to develop streamflow and water availability forecasts from space-based data. Traditionally, such information requires significant on-ground data and complex analysis tools. The pilot highlights the potential of the integrated suite of tools to significantly increase the information available to water and agricultural managers and farmers to anticipate and plan for drought conditions.
Further, the use of Open Data Cube technology enabled many Source model inputs to be generated automatically, reducing the time to build the model, potentially making modelling more accessible to water managers.
The information was made available in a relatively simple format and accessed through mobile technology via https://escap.ewater.org.au/
