Ross has designed and supervised onground waterway management and rehabilitation programs including management of waterway avulsions, stream bed and bank erosion, sediment management, willow management and streamside revegetation.

Ross is the author of the “Technical Guidelines for Waterway Management” a technical manual on the design and implementation of stream management works for the state government of Victoria, and has conducted training courses in Tasmania, Victoria, South Australia and Queensland on the application and implementation of the principles of geomorphic channel design.

Dom Blackham

Dom is a fluvial geomorphologist with particular expertise in geomorphic investigation and analysis, stream rehabilitation, stormwater management in urban waterways and post-bushfire catchment response. Dom has worked as a consultant and researcher in Australia and UK for the last 20 years.

Dom was a member of the Co-operative Research Centre for Catchment Hydrology (now eWater CRC) and carried out research into the role of riparian vegetation in controlling stream channel erosion funded by Land and Water Australia. The key finding from his research was that exotic grasses such as Phalaris spp. provide significant resistance to erosion and their removal through weed control and native revegetation programs may have the unintended consequence of increasing erosion rates.

Dom’s consulting activities have focussed on combining hydrology, hydraulics and fluvial geomorphology to develop sustainable catchment and river management solutions. He has been closely involved in the development of geomorphic flow objectives to control the impact on channel form of stormwater runoff from urban development and the assessment of various risks to river health and engineering infrastructure following bushfires. Dom maintains close links with research and academia through his Honorary Fellowship at Melbourne University and informal links with various researchers at eWater CRC.
