Occupation
Hydrologist
Hydrologists study how water moves through and is stored in the environment: rivers, aquifers, catchments, and the systems built around them. The work supports flood risk assessment, water supply planning, contamination investigation, and environmental permitting. It combines field measurement with modelling and a good deal of regulatory reporting.
Also known as: Hydrogeologist · Water resources scientist · Flood risk analyst
