What is Fluvial Geomorphology?

Fluvial geomorphology is how rivers shape the world, and, in its most simplistic form is the interaction between sediment, water and vegetation throughout a river catchment. It is a specialist technical area which focuses on understanding and explaining river processes and how they change through time.

An understanding of river character and behaviour is key to understanding how rivers may behave in the future and under changing conditions (such as climate change or land-use changes). This information provides a holistic and long-term foundation for river management plans, flood risk assessments, erosion mitigation, gravel resource management, ecological assessments and enhancements, as well as fish passage design, stream diversion design, and stream enhancement projects.

Our fluvial geomorphologists at T+T regularly collaborate with water engineers, river managers, ecologists, freshwater scientists, landscape architects and Geotech engineers across a wide range of disciplines and industries to get the best outcome for our varied clients in New Zealand and Australia.

Recent projects include a sedimentation study in the Manawatū River for Horizons Regional Council and geomorphic trends assessment as input into the Waiohine River floodplain management plan for Greater Wellington Regional Council.
