Biography

Dr. Klaus Joehnk is a Principal Research Scientist in CSIRO Land and Water leading the Modelling Water Ecosystems team. He has over 20 years of experience in research and consultancy on hydrodynamic and water quality modelling of lakes and rivers in Europe and Australia. During the last years he has been leading projects on combining hydrodynamic and water quality modelling with satellite remote sensing of inland waters with a goal of operational short-term forecasting of harmful algal blooms. Further areas of research are modelling of low dissolved oxygen - blackwater - events in river systems for risk reduction of hypoxia and fish kills, large scale modelling of hydrological and thermal conditions in river systems to support a release strategy of carp herpesvirus for pest reduction, and in general utilizing modelling tools in combination with remote sensing to better manage water dependent ecosystems. During and after the bushfires in Australia 2020 he led a research group to investigate the effects of bushfires on water quality. Klaus is also working as part of the AquaWatch Australia mission team to develop a satellite based monitoring and forecasting system for inland water quality on a continental scale.

Dr. Joehnk has over 50 publications in International Journals and Conference Proceedings. He serves on the editorial board for Ecological Informatics (Elsevier) and is Associate Editor for Frontiers in Environmental Science - Interdisciplinary Climate Studies. Dr Joehnk is a committee member of the Australian Water Association/ACT branch.

Research areas:
Dr Klaus Joehnk's primary research area is environmental modelling of climate-driven aquatic systems. His special research interests include:
* Dynamics of cyanobacteria blooms
* Remote sensing of water quality
* Continental scale modelling of aquatic systems
* Climate change impact on stratification of lakes
* Mine pit lakes

Project lead over the last 5 years:
* Water quality responses and mitigation options for post 2019/20 bushfire floods in the MDB (2020)
* Assessment and mitigation options of blackwater risk in the Murray River system (2018-2020)
* Development of hydrological, ecological and epidemiological modelling to inform a CyHV3 release strategy for the biocontrol of carp in the Murray Darling Basin (2017-2019)
* HIREMOT - High-resolution in-situ and surface measurements of optical and temperature lake characteristics – AQUACOSM H2020 (2020)
* Development of bloom remote sensing capability and cyanobacteria forecasting model for Western Treatment Plant’s largest treatment lagoon systems (2017-2018)
* Lake Hume blue-green algae risk minimisation (2017-2018)
* A national framework for prediction of Harmful Algal Blooms (2015 - 2017)
* Murray River Decision Support System - blackwater, harmful algal blooms (2015-2017)
* Coorong hydrodynamics and macrophyte+fish habitats (2013-2015)
* Western Port Bay sediment transport (2014-2016)
* Wave model in the Great Barrier Reef and estuaries (2011-2016)
* Lake model inter-comparison project (LakeMIP)
* Lake temperature variability on a continental scale
