Avon Otakaro Network Hydraulic Modelling

avon_birds.JPGThe Avon-Otakaro Network (AvON) is a community led group with a strong sustainable vision for Christchurch’s Red Zone, aiming to restore and enhance the ecosystems, natural habitat, biodiversity and recreation of the city’s waterways.


In 2014, EWB was involved in the technical support of the Mahinga Kai project, focusing on the analysis of the Kate Sheppard waterways complex in Christchurch East.

UC student Duncan Keenan spent his summer collecting data, including water levels, tidal flows and salinity, with professional EWBNZ volunteer Ben Throssall who utilized the data to create detailed hydraulic and salinity models. These models helped deepen the group’s understanding of the waterways and allowed them to predict scenarios beyond those observed in the field. Their work highlighted how much more there is to learn about the waterways, with the potential for the projects to be extended with continued support from EWBNZ.
