- The effect of landuse, landscape and climate on movement of water and salt in upland environments
- The effect of changes in landuse particularly pastures on interception of water
- The various ways dryland salinity expresses itself in the central west of NSW
David Mitchell is trained in soil science and surface hydrology. He has 20 years experience in soil physical/ surface hydrology research. He has led several large multidisciplinary research projects, specifically the Key Sites project. Key Sites is a state-wide project studying the various ways dryland salinity is expressed and the subsequent on farm management actions that can be taken to mitigate or reverse the effects of dryland salinity.
Currently David is a partner investigator with the National Centre for Groundwater Research and Training, researching the effects of the recent high rainfall on dryland salinity remediation methods, as well as the role climate and land use has on interception.
He joined NSW Agriculture* in 1992 as technical officer undertaking soil physical research, he spent thee years at CSIRO Townsville undertaking a PhD in surface hydrology before returning to NSW Agriculture as a research officer in the NSW Water Use Efficiency Unit.
David led the Key Sites project from 2005 to 2009.
*NSW Department of Primary Industries was formed on July 1, 2004 through an amalgamation of NSW Agriculture, NSW Fisheries, State Forests of NSW and the NSW Department of Mineral Resources.
