RESEARCH GROUP

Geochemistry and Hydrology Division

Updated: October 2025

Research by members of the Division of Geochemistry and Hydrology seeks to understand the biogeochemical and hydrological processes that control the quality and amount of water across spatial and temporal scales.

The studied spatial scales vary from ephemeral headwaters to river mouths and the temporal scales that range from runoff episodes to the 60 years covered of national surface water data and even the millennia revealed by palaeoecological archives. This research supports the Department’s mission to assess how aquatic life as well as aquatic ecosystem services such as drinking water quality/amount are influenced by human activities including agriculture, forestry, climate warming and the deposition of atmospheric pollutants. Since aquatic carbon is critical for water quality, this is also a research specialty.

The division’s research often concerns measures (e.g. land-use planning, wetland and lake restoration) to help society achieve its water-related goals. This involves development of process level knowledge through dedicated field measurements, lab experiments and modelling.

The department’s role in environmental monitoring and assessment is an inspiration and resource for the group’s research.  Responsibility for national water quality monitoring programs involves extensive stakeholder interaction and engages group members in advancing the science of monitoring and assessment. This includes pioneering new measurement technologies and assessment methodologies.
