When: 20th April 2023 (11.30 AM – 2.30 PM AEST)

Where: Rooms G29 and G30 (Ground floor), New Horizon Building, 20 Research Way, Clayton VIC 3800, Department of Civil Engineering, Monash University, Melbourne

Format: Hybrid event

Target participants: The meeting is open to everyone but the main audience will be utilities, water managers and representatives from local and regional stakeholders within the Murray-Darling Basin


Many inland water bodies in Australia and around the globe often experience algae blooms that can impede public health since many of them supply household needs for towns and landholders. In Australia, water from reservoirs is mainly used for stock needs, irrigation, recreation, flood mitigation, and hydroelectricity, demonstrating the significant socioeconomic impact that water quality outbreaks might incur.

PrimeWater is a Horizon 2020 (the EU Research and Innovation program) funded project, that aims to maximize the potential of the Earth Observation (EO) technologies for the water sector by enhancing and expanding the information base for inland water quality attributes, integrating multi- and hyperspectral imagery from satellite, airborne and ground-based sensors with models, increasing the situational intelligence of water regulators, emergency planners, water-related industry professionals, and local communities.

Lake Hume and Melbourne Water are the case studies where the PrimeWater consortium explored the predictability of algal blooms – in terms of timing, extent, and intensity employing both process-based and data-driven, machine learning models.


This workshop intends to initiate a discussion on short to medium-term water quality forecasts into an early warning service for HAB outbreaks. The main objectives of the workshops are:

  • To inform local/regional end users of the findings of the PrimeWater and demonstrate operational forecasting service for inland freshwater
  • To discuss how forecast-based early warning services for HAB can improve risk management operations
