Our researchers are working on innovative engineering solutions in the following focus areas:
- spatial sampling for land use management in urban and rural catchments
- smart monitoring and management of water infrastructure
- porous earth technologies for aquifer assets
- decentralised and alternative water systems
- stormwater harvesting into the urban water supply-quantity and quality aspects
- water supply catchment modelling
- quality classes and water supply sources in urban developments
- scale-modelling catchment, soil and water.
Smart water system design and data analytics
Ageing water assets results in about 19,000 pipe breaks every year in Australia and cost billion of dollars to maintain and repair. Meanwhile, emerging smart water technologies, including Internet of Things (IoT) based remote sensing, artificial intelligence (AI), machine learning and advanced data analytics, have provided opportunities to enable sustainable water asset management.
In collaboration with Australian water utilities and other research institutions, we are developing tools to make the most of the investment in smart water and wastewater networks. We transform data to meaningful information, which allows a proactive, instead of reactive, asset management.
Aerated furrow irrigation with runoff recycling (AFIRR)
Out of the 2-million-hectare irrigation industry in Australia, 900,000 hectares are under surface gravity irrigation. Excessive deep drainage is a major drawback of surface furrow irrigation systems. The current situation is exacerbated by the extensive use of heavy machinery on land, which compacts soil and results in less plant respiration and lower yields. This project aims to improve soil, air and water bonds for both saving water and increasing yield by simultaneous application of water on the surface and air injection below ground which is the so-called aerated furrow irrigation with runoff recycling (AFIRR). Our initial physical modelling of AFIRR indicates a 5% increase in soil moisture retention and 15% of total water applied as recycled tailwater runoff, showing a 20% improvement in water application efficiency.
Water storage underground
Around 97% of the world’s liquid fresh water is stored in aquifers. Water supplies from underground have many advantages including: no losses due to evaporation, the availability of local aquifers in many regions, and they provide modular asset development opportunities. It's typically less expensive to use local groundwater than to pipe, pump and treat water sourced from outside the region. However, groundwater supplies must be used in a sustainable manner and managed for any underground engineering project such as tunnelling and mine construction. Interactions of groundwater with surface waters and other assets must be carefully evaluated using a range of monitoring, site investigation, water tracer techniques, drilling and core testing, as well as computer modelling.
Our current projects include research in:
- the sustainability of aquifers for supplying water for town water, irrigation and baseflow to rivers
- advanced pore pressure analysis methods using passive and inexpensive techniques
- innovative ground testing methods and sensor systems
- groundwater management for engineering projects such as tunnelling and mining
- water tracer technologies for investigating recharge, mixing and inter-aquifer interaction.
