PROJECT 2.7: Refining Australia’s water futures
This project ran from 1 July 2016 until 30 June 2019
Information about, and analyses of, future water availability are critical for water resources planning and investment decisions; however, consistent projections for a range of hydroclimate variables (e.g. rainfall, surface run off, lateral water flow, soil moisture) and drought metrics are not currently available.
We’ve worked with state and federal government and water managers to identify gaps in hydroclimate metrics and improve climate-water modelling. Building on existing science, we have develop methods to deliver next generation projections of future water availability and hydrologic variables or metrics important to the water and related sectors.
This will improve Australia’s ability to assess the impact of climate change on Australia’s hydroclimates and water resources, and inform planning and climate change adaptation in the water and related sectors.
Outcomes from this project will be used in the current Hub Project 5.4 – Water futures under climate change.
Key project achievements include:
- Improved and undertook integrated climate-water modelling and projections
- Developed and implemented research case studies with key stakeholders in the water sector, gaining an improved understanding of the water sector’s climate change information needs and challenges

This project is contributing to meeting the following climate challenges:
Improved modelling developed in this project will enhance the quality of projections that are available to water managers and planners.
Agricultural and environmental system managers and planners will be able to use projections developed from work in this project to make more effective management and investment decisions.
