Associate Professor David Kennedy
David is a coastal geomorphologist and spends his time studying: rocky shores and platforms; coral reefs and islands; sandy beaches; gravel beaches; and muddy estuaries. Part of his research is also understanding the impact of storms, tsunami , sea level change, sedimentation, and human modification on these coastal landforms.
Cutting-edge methodological design and practice are central to his research and teaching. This includes UAV/Drone and aerial laser surveying, through to isotopic chemical methods and traditional geomorphic hole-digging. He is also at the forefront of eLearning having received several grants for the development of online teaching tools.
David’s research is highly applicable beyond the academic environment having presented invited public talks at community forums throughout Victoria and being interviewed widely for national and international media. Putting research into practice is a core endeavour of this work.
Visiting fellow from Otago University
I am a coastal geomorphologist with connections to ecology and conservation management. My research interests lie at the interface of physical geography and ecology with a focus on the response of bio-geomorphic systems to disturbance. My research to date has been largely concerned with dunal and sandy coasts, since the morphology and dynamics of coastal dunes are governed in large part by the distribution, density and growth forms of associated plant communities and species. Recent projects have involved the measurement of aeolian sand transport and deposition over vegetated foredunes, the impact of invasive sand-binding plants on dune morphology and ecology, and the development of methodologies to evaluate the geomorphic success of coastal dune restorations. Current research examines the sensitivity of the Victorian coastline to erosion under future climates.
My study investigates an invasive, exotic coastal grass, and its arbuscular mycorrhizal (AM) fungal symbiont. The fungi exchange nutrients and water for carbohydrates, in some 90% of terrestrial vascular plants. Natural Resource Managers are concerned that the exotic grass, Sea wheatgrass (Thinopyrum junceiforme) is out-competing the native Hairy spinifex (Spinifex sericeus), but how or why is not currently addressed in the literature. Through field work and experiments, I am testing my hypothesis that Sea wheatgrass has more AM fungi than Hairy spinifex, so it is getting the lion’s share of nutrients, enabling it to rapidly spread and colonize the dunes.
My research focuses on which elements of the rocky coast environment are perceived as being hazardous and how those perceptions relate with physical elements to produce risk. Using high-risk locations in coastal regions of Victoria and New South Wales, Australia, as the case, my research investigates the complex socio-environmental relations that produce risk. In particular, my work emphasises the deep contextualised understanding of risk that is developed through first-hand experience.
I am a second year PhD student studying the evolution of rocky coasts over multiple glacial cycles. My work focuses on the modern coast of Victoria, as well as paleo-shorelines found offshore that have been preserved below modern sea level. One of the most exciting discoveries made during this work has been that of the Drowned Apostles, a group of 60,000 year old sea stacks found at 50m depth offshore of the modern 12 Apostles along the Great Ocean Road. By studying these submerged features and their contemporary counterparts onshore, an evolutionary model of how coasts form and evolve over time will be created not only for Victoria but for rocky coasts across the world.
I have recently commenced my research program with the University of Melbourne on a part time basis while still employed as an Environmental Engineer with the City of Greater Geelong. My research aims to explore the application of ecological engineering in coastal areas to address coastal hazards in environmentally sensitive areas and asses the benefits of ecosystem services that these approaches may deliver. As part of managing natural resources, in particular coastal areas on the Bellarine Peninsula and Corio Bay, my work involves the delivery of capital works some of which aim to address the impacts of coastal hazards that result in erosion and / or landslides. As a key part of my research I will be applying a living shoreline approach by incorporating the establishment of an offshore breakwater in the form of an artificial reef and on shore treatments to stabilise the foreshore and consolidate the primary dune / berm.
I am researching the role of vegetation in foredune morphology. Predicted scenarios for climate change include rising sea levels and increased storm events, I am interested in studying the role of vegetation in mediating erosion on the backshore. My study sites will be located at Summerland’s Bay on Phillip Island Victoria.
My research topic is sand dunes along the Victoria coast. Sand dunes are of significant ecological importance and could also be the most economical natural defence against coastal erosion caused by storms and rising sea levels. My study will investigate the changes of sand dunes in Victoria area during the last several decades. Specifically, changes in bare sands and vegetated dunes as well as their movement rates will be quantified. To explain these changes, both natural factors and potential human influences will be examined. Modelling will also be applied to predict trends in sand dune change.
My research topic is about the seasonality of hourly-scale surface changes on shore platform. With the traversing micro-erosion meter (TMEM), the elevation of rock surface can be measured. I’m exploring the drivers for the short-term micro-topography change. By studying this phenomenon, it will facilitate to better explore the effect of short-term changes on T/MEM measurements, the calculation of vertical weathering rates and the development of shore platform at larger spatial and temporal scales.
