My 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. Observations will use a high-resolution LiDAR system to provide 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.
