Geoff Vietz's Profile Picture

Geoff Vietz


Dr Geoff Vietz is a geomorphologist and water management specialist with 18 years experience in catchment, river and wetland management.

Geoff is a Research Fellow at the University of Melbourne where his research is focused on the geomorphology, ecohydraulics and sustainable management of streams and wetlands.

He has authored or co-authored over 100 journal papers or technical reports and lectured on fluvial geomorphology, hydrology, river rehabilitation and environmental flows. He is a former co-leader of the stream ecology program for the Cooperative Research Centre for Water Sensitive Cities and a member of the Waterway Ecosystem Research Group.

Geoff is also the principal of Streamology (, a consulting company focused on narrowing the research-consulting divide and ensuring novel and appropriate solutions are applied to waterway, wetland and water resources management. Geoff has been in technical and managerial roles on projects throughout Australia and internationally. His specialties include geomorphic investigations and environmental flow studies as they apply to both rural and urban environments, in addition to extensive experience in river rehabilitation, monitoring and evaluation, and strategic water resources management. Geoff is immediate past-president of the River Basin Management Society and a Fellow of the Peter Cullen Water and Environment Trust.
