Mr Jonathan Cohen


Jonathan Cohen is a PhD candidate of the School of Natural and Built Environments (NBE) at the University of South Australia (UniSA).  In 2011 he graduated from UniSA with a Master’s in Environmental Management and Sustainability, specialising in water management.

His PhD research will focus on improving our understanding of the impact of different vegetation types, soil types climate and seasonality on formation and changes of natural organic matter (NOM) in sub-catchments, and its impact on surface and shallow subsurface water. The research will also focus on testing the treatability of differ NOM fractions using hydrolysed poly-coagulants.  Based on this study, a data base will be developed for supporting catchment management decision-making. This research will help improve our understanding of the connection between catchment management and NOM which is still only partially understood. This has resulted in a lack of effective methodology for the prediction and assessment of the effects of catchment conditions on the impacts of NOM on drinking water quality. The research will focus both on field studies of sub-catchments of Myponga and Mt Bold reservoirs in SA and on soil leaching experiments under laboratory conditions.
