Studying towards a PhD in Water Resource Management
A numerical simulation of fine sediment dynamics in the lower Rangitata River in response to different flow regimes, supported by complete substrate mapping, with a view to informing flow management of the River and its impact on ecological values.

Justin’s PhD research involves observing and modelling the fine sediment dynamics of the Rangitata River and understanding the river’s morphological response to flow abstraction. The project is funded by DoC and supervised by Dr James Brasington of Waterways, Dr Jo Hoyle of NIWA and Dr Jono Tonkin at UC Biology. A high-resolution LiDAR system has provided unprecedented view of the river’s form and composition, supplemented by photography and in-river surveying. Modelling at multiple scales will seek to understand the behaviour of ecologically problematic fine sediment in space and time.
