Dr Tapas Biswas

Senior Research Scientist

Tapas is a water quality researcher with expertise in measuring, monitoring and managing inland water quality using smart and emerging technologies.


Dr Tapas Biswas is a Senior Research Scientist in CSIRO L&W, leading the water quality research in the Modelling Water Ecosystems team. He has 32 years of experience in research, teaching and consultancy on soil and water resource management in Australia, Asia and America. Tapas has managed numerous large-scale research programs involving multi-jurisdictions within the Murray-Darling Basin and overseas. The recent focus of his work includes river productivity responses to environmental watering; freshwater quality responses to anthropogenic changes; bushfire impacts on catchment water quality; and continuous forecast of harmful algal growth in freshwater bodies.

Tapas is actively using in-situ sensors to accurately estimate key water quality indicators in real-time in order to inform sustainable water management decisions. His work with on-ground sensors aims to calibrate AquaWatch, Australia’s first satellite system, to monitor water quality from space.

General research areas:

  • Water quality monitoring and modelling
  • Dryland and irrigation salinity
  • Remote sensing and early warning tools for water quality change
  • Dynamics of cyanobacteria blooms and blackwater in lowland rivers
  • Impacts of bushfire on river and lake water quality
  • River productivity (carbon, nutrients, dissolved oxygen, phytoplankton)
  • Wastewater reuse and zero discharge Biosystems
