Past NZ Rivers Group Events
Join Kyle Christensen in an interactive session to find out about the factors that contributed to the failure of the floodwall at Edgecumbe in the 2017 flood (note – this was presented at the 2019 River Managers/Rivers Group Workshop on Whakatane). The presentation will be 30 – 40 mins with time for questions/discussion afterwards.
Please join us for an afternoon showcasing the cutting-edge river related research (broadly defined) currently taking place across the University of Auckland.
We will hear talks of the latest research from students and also hear keynote talks on how river research can be translated into effective river management and practice in New Zealand. There will be a prize for best student presentation on the day, and the relaxed atmosphere will present multiple opportunities to mingle and network with colleagues, students and staff at the University.
- Friday 20 March: If you would like to give a talk, please send a title and short (100 word) abstract by then to Edwin Baynes (firstname.lastname@example.org). Please encourage your students to submit a title, and if you have something exciting that you would like to talk about then please also feel free to submit a title.

The International Association for Hydro-Environment Engineering and Research (IAHR) and the Engineering New Zealand/Water New Zealand Rivers Group in association with the University of Auckland are proud to announce the 11th River, Coastal and Estuarine Morphodynamics Symposium – RCEM 2019, which for the first time comes to Aotearoa, New Zealand, land of the long white cloud.
2019 promises to be a unique and memorable event as the River, Coastal and Estuarine Morphodynamics Community celebrates its 20th year anniversary. The Conference will be hosted in Auckland from 16-21 November 2019.
Celebrating 20 years, the theme of the Conference is “Ka mua, ka muri: Looking back, moving forward”, and the programme will include plenary speaker presentations as well as special and contributed sessions, poster displays, a diverse array of exhibits, networking functions, and field trips that showcase Auckland’s unique natural environments and attractions.
New Zealand is home to some of the most spectacular water-shaped morphodynamic locations worldwide. The Conference will be held in early summer in the city of Auckland, within walking distance of the CBD, museum, art gallery, parks and the Waitemata waterfront. Imagine an urban environment where everyone lives within half an hour of beautiful beaches, hiking trails and a dozen enchanted holiday islands including Waiheke and Great Barrier Islands. Auckland is boasting three harbours, two mountain ranges, 48 volcanic cones and more than 50 islands.
We are looking forward to seeing you in Auckland in November 2019. Nau mai haere mai! Welcome!

New Zealand river managers and engineers are tasked with working in some of the most dynamic river systems in the world. Sudden and rapid changes in these channels can render control and modification structures redundant, threaten their integrity, or undo months of river control work.
In this workshop we will introduce the key processes driving river behaviour in New Zealand. Our premise is that understanding these processes is key to working with them, rather than against them. In turn, working with the dynamics of the river is critical for effective and sustainable river management, to reduce the risks of failure and loss of infrastructure and capital, and even improve the aesthetics and habitat of managed river reaches.
We invite participants to discuss particular issues and sites that they may be working with currently or expect to engage with in the future, to connect our theory with your practice. Problem-cases in particular are welcome to discuss in a BYO case study session.
The workshop is facilitated by Professors Ian Fuller & Russell Death, Innovative River Solutions Group, School of Agriculture & Environment.

Although confluence flows are ubiquitous, occurring in geophysical systems, such as river networks, mechanical systems, such as duct or pipe networks, and biological systems, such as arterial or venous networks, understanding of the fluid dynamics of confluences is limited.
This research proposes a generalized framework characterizing the fluid dynamics of open-channel confluences with a concordant bed, including an-in depth investigation of the physics of shallow mixing layers developing over a no-slip surface. Using eddy-resolving numerical simulations in idealized geometries, we systematically examine the main parameters (confluence angle, velocity ratio, density ratio, curvature of the downstream channel) that control confluence fluid dynamics and the influence of this dynamics on mixing between the two incoming streams. In particular, we investigate the role played by the quasi-2D large-scale eddies generated within the mixing interface and by the streamwise-oriented vortical (SOV) cells forming in the vicinity of the mixing interface in mixing.
We show that the main reason why SOV cells have a large capacity to enhance mixing and to entrain sediment from the bed in the case of a loose-bed boundary is because their cores are subject to large-scale bimodal oscillations toward and away of the mixing interface.
Finally we discuss some examples where shallow mixing interfaces form at river confluences with natural bathymetry and in particular the role played by density differences between the incoming streams on hydrodynamics and mixing of concordant bed confluences.

The ability of animals to sense and navigate complex environments is unrivaled by even the most sophisticated robots known to humans. Nowhere is this more challenging to understand than in the three-dimensional environment of water, where animals are unconstrained by gravity, often in turbulence flows, and appendages and bodies are at the mercy of complex fluid-structure interactions.
Fishes, which comprise over half of all living vertebrates, have an exquisite control mechanism for negotiating turbulence. I will describe advances my lab has made in understanding how fish swim in unsteady flows, and how by study nature’s designs we can reveal insights into some of the biggest challenges in engineering and robotics.

Why attend the “lessons learnt from the large flood events in the Bay of Plenty Region” workshop?
The River Manager’s forum is a group of river managers from all regional and unitary councils across New Zealand, who come together to share knowledge, experiences and lessons learnt in the management of New Zealand Rivers from a council perspective. The Rivers Group is a forum for all those with an interest in rivers, flood risk management and the operational and environmental issues of catchments and river systems.
Understanding River Management in the Bay of Plenty
Understanding the events leading up to large flood events, things that unfolded during those flood events, and the response from the Regional Council and Civil Defence, help us collectively to understand and plan for future flood events.
- Learn about the Rangitāiki River flood scheme and the Rangitāiki floodway, and some of the challenges the council faces moving forward.
- Hear about BOPRC’s flood forecasting model for the Rangitāiki River, and how it performed in light of the 2017 flood event.
- Learn more about the three major flood events that have occurred in the Bay of Plenty in the last few years, and the independent reviews and recommendations from two of these.
- This event is a unique opportunity to network with river professionals and leaders in river management.
- There is an opportunity for robust discussion with the BOPRC river management team during the panel discussion.
- Inspire each other with our stories of success, challenges and celebration.
- Participate in an interactive field trip through the Rangitāiki River with those involved with managing the river.
