Fluvial geomorphology is the study of how rivers shape the world around us. At its core, it examines the intricate interplay between sediment, water, and vegetation throughout an entire river catchment. By understanding the complex processes in a river system, we can gain insight into how it might behave in the future, particularly under changing conditions such as climate change.
At Tonkin + Taylor, we have a team of expert fluvial geomorphologists with proven technical capability and project experience.
Our fluvial geomorphology team work closely with water engineers, river managers, ecologists, freshwater scientists, landscape architects, and geotechnical engineers to provide our clients with holistic, long-term solutions. By collaborating across a range of expertise and industries, our fluvial geomorphology team can provide tailored solutions that consider each river system’s unique characteristics.
Tonkin + Taylor fluvial geomorphology team aim to provide our clients with robust solutions through improved river management, flood risk assessments, erosion mitigation, gravel resource management, ecological assessments and enhancements, fish passage design, stream diversion design, and stream enhancement initiatives.
Award-winning project highlight: The Kōpūrererua Stream Realignment Project
The Kōpūrererua Stream Realignment project is a collaborative endeavour initiated by Tauranga City Council (TCC) with the support of Bay of Plenty Regional Council (BOPRC) and Ngāi Tamarāwaho. This project won in the Healthy Parks Award category at 2025 New Zealand Park Awards.
“It’s been incredibly rewarding to see the ecological effects already – birds returning, fish establishing in the new stream reaches, and the meaningful involvement of local iwi as kaitiaki of this area.” – Josh Hodson, Senior Water Resources Engineer.
