The need of assessing the impacts of natural hazards such as sea level rise and storm surge for coastal areas becomes more and more important as an increase in human population in these areas is apparent. Focusing on New South Wales, where the majority of the population is located in the coastal zone, the aspects of a rising sea level and potential storm surge have to be considered. This situation will worsen as the highest population growth is found in coastal local government areas. Collaroy/ Narrabeen Beach has the most intense and highly capitalized shoreline development in New South Wales. Given that risk (R) is a function of hazard (H) and vulnerability (V) over time (t); i.e., R = f (H, V, t) expressed in monetary terms, Collaroy/Narrabeen Beach is the beach most at risk in New South Wales. By using already available information, such as property information data from local government or hazard information from the New South Wales Department of Land and Water Conservation, a formal method is developed and incorporated into a geographical information system to assess quickly areas at risk. A generalized risk zone then represents possible present and future areas at risk weighted in terms of hazard level and exposure values.
Catharina Greve studied Geography at the Department of Geography, University of Kiel, Germany, where she finished her Master's thesis in 1995. Her main emphasis during her studies as coastal geography in both physical and socioeconomic geography. Catharina worked with different Geographic Information Systems (GIS), and her Master's thesis was based on the application of GIS for the analysis of future tourism trends on the former East German island Ruegen with respect to ecological aspects. She started her Ph.D. as a full-time student at the Coastal Studies Unit, School of Geosciences, University of Sydney, in March 1996 and is involved in a climatechange coastal impact project funded by the National Greenhouse Advisory Committee (NGAC) and the Deutscher Akademischer Austauschdienst (DAAD), Germany.
Peter Cowell is Senior Lecturer at the Coastal Studies Unit in the Marine Studies Centre and School of Geosciences at the University of Sydney. His research on coastal morphodynamics ranges from instantaneous processes to coastal evolution on time scales of centuries and millennia. This work focuses on the application of computer-based Geographic Information Systems both in coastal marine science and land management.
Bruce Thom is Emeritus Professor of Geography, University of Sydney and Visiting Professor of Geography, University of New South Wales. He also holds the chair of the New South Wales Coastal Council and has 35 years scientific experience in coastal geomorphology and Quaternary geology. Thom has a general interest in Quaternary environmental change, with a specific interest in depositional histories of coastal, sand barriers, and estuarine sequences of late Pleistocene and Holocene age. Other interests include evaluation of the magnitude and frequency of coastal erosion events and the development of long-term management strategies to cope with periods of severe coastal erosion. The interaction of plant communities and landforms in the coastal zone, especially mangroves, constitutes another research activity.
