Natural hazards in Australia: floods

Natural hazards in Australia: floods

Floods are caused by a number of interacting factors, making it remarkably difficult to explain changes in flood hazard. This paper reviews the current understanding of historical trends and variability in flood hazard across Australia. Links between flood and rainfall trends cannot be made due to the influence of climate processes over a number of spatial and temporal scales as well as landsca...

Natural hazards in Australia: heatwaves

As part of a special issue on natural hazards, this paper reviews the current state of scientific knowledge of Australian heatwaves. Over recent years, progress has been made in understanding both the causes of and changes to heatwaves. Relationships between atmospheric heatwaves and large-scale and synoptic variability have been identified, with increasing trends in heatwave intensity, frequen...

Natural hazards in Australia: droughts

Droughts are a recurrent and natural part of the Australian hydroclimate, with evidence of drought dating back thousands of years. However, our ability to monitor, attribute, forecast and manage drought is exposed as insufficient whenever a drought occurs. This paper summarises what is known about drought hazard, as opposed to the impacts of drought, in Australia and finds that, unlike other hy...

Natural radioactivity in ceramic tiles and associated radiological hazards

Background: The natural radioactivity levels in ceramic tiles produced in Turkey were determined and the related radiological hazards were assessed. Materials and Methods: The natural radioactivity levels (226Ra, 232Th and 40K) in the ceramic tiles were measured using high-purity germanium detector system (HPGe) and the related radiological hazards were assessed by radium equivalent activity (R...
