Impact of fire on groundwater recharge

Wildland fires are increasingly common and severe, significantly impacting drinking water resources. While predictions of post-wildfire stream flows exist, our understanding of fire effects on groundwater recharge remains limited. In this talk, we introduce a conceptual model that illustrates the time-variable nature of recharge and identify the conditions under which it should be applied. We also demonstrate methods for evaluating spatial variations in recharge following wildfires. Lastly, we discuss the need for targeted monitoring efforts if adverse trends in the wildfire regime continue. This talk aims to enhance our understanding of fire-water interactions and inform strategies for sustainable water resource management in fire-prone regions.

About the speaker:

Dr. Konrad Miotliński is a hydrogeologist with 20 years of international experience in research, academia, and consulting. He is passionate about water quality and the development of computational models to address complex issues in water resources. Recently, Konrad developed a model to assess the impact of wildfires on drinking water quality in the Perth Hills catchments.
