Mal Green, PhD

Estuarine, Coastal & Marine Specialist

Mal specialises in estuarine sediment transport. He has a BSc (1st Class Hons) from the University of Sydney and a PhD from the Virginia Institute of Marine Science. Before emigrating to New Zealand, he spent 6 years at the University of Cambridge (UK) researching sediment dynamics in the shallow seas around the British Isles. His current research interests, which have brought him into shallower water, include sediment transport in tidal creeks, wave-driven sediment transport in estuaries, boundary-layer flows over shellfish beds, and prediction of decadal-scale estuarine sedimentation. He has a particular interest in limits-based management, and is currently developing the concepts and analytical methods required to implement catchment contaminant load limits to achieve environmental objectives in estuaries.

Mal was awarded the 2009 Kudos Award for Environmental Science in recognition of his leading role in applying science to issues threatening our coasts. As well as providing cutting-edge science relevant to client needs, Mal is very well known amongst resource management practitioners as an excellent environmental science facilitator. He is also an experienced project manager and has considerable experience in leading large, multi-disciplinary teams. Until recently, Mal was Principal Scientist, Coastal and Estuarine Physical Processes at NIWA, as well as Leader of their Catchments to Estuaries Programme.
