Surface water modelling and analysis tools provide technical support to:
- Inform the operation of large and complex water supply systems;
- Understand the projected impacts of climate change on water availability and assess water supply system augmentation options;
- Maintain and improve Victoria's water allocation framework;
- Demonstrate compliance with intestate water sharing arrangements developed for the Murray-Darling Basin;
- Quantify and verify water savings arising from irrigation modernisation works and conservation and efficiency programs;
- Monitor, assess, forecast and report on Victoria's water availability and use;
- Develop and implement long term water resource plans such as regional Sustainable Water Strategies, Long Term Water Resource Assessment and Urban Water Strategies;
- Develop and implement measures for extreme conditions such as dry condition preparedness and flood management plans;
- Establish sustainable limits on the amount of surface water that can be diverted from a river system; and
- Develop environmental watering plans.
The Department of Environment, Water and Planning (DELWP) is a key contributor to the development and maintenance of surface water modelling software utilised by the Victorian water industry.
The Department is contributing to the development and maintenance of new surface water modelling platform, Source, developed by eWater on behalf of Australian governments (the Commonwealth and state governments of NSW, Victoria, QLD, SA, WA and ACT). Source is designed to simulate all aspects of water resource systems to support integrated planning, operations and governance from urban, catchment to river basin scales, including human and ecological influences.
The Department have developed a strategy to transition from the current widely used REALM software to Source software.
In addition to Source, the Department contributes to the maintenance of legacy water resource allocation software and specialist farm dam impact estimation software.
The Resource ALlocation Model (REALM) can simulate both simple and large complex water supply systems.
The Spacial Tool for Estimating Dam Impacts (STEDI) can simulate the impact of farm dams on streamflow.
