The global impacts of river floods are substantial and rising. Effective adaptation to the increasing risks requires an in-depth understanding of the physical and socioeconomic drivers of risk. Whereas the modeling of flood hazard and exposure has improved greatly, compelling evidence on spatiotemporal patterns in vulnerability of societies around the world is still lacking. Due to this knowled...
Flood flows in inundated urban environment constitute a natural hazard. During the 1213 January 2011 flood of the Brisbane River, detailed water elevation, velocity and suspended sediment data were recorded in an inundated street at the peak of the flood. The field observations highlighted a number of unusual flow interactions with the urban surroundings. These included some slow fluctuations i...
Information is provided on the approach and experience in flood management in the Piemonte Region. Actual practices comprise mainly: (i) the structural mitigation of floods; and (ii) non-structural safety measures subdivided into land use planning and emergency plan activation through hydrometeorological forecasting and the development of an Alert System for flood forecasting and warning. Of pa...
Remotely sensed flood extents obtained in near real-time can be used for emergency incident management and as observations assimilation into forecasting models. High-resolution synthetic aperture radar (SAR) sensors have the potential to detect urban areas through clouds during both day- night-time. This paper considers a method detecting flooding by merging SAR with model-derived hazard maps. ...
Flooding is a very costly natural hazard in the UK and is expected to increase further under future climate change scenarios. Flood defences are commonly deployed to protect communities and property from flooding, but in recent years flood management policy has looked towards solutions that seek to mitigate flood risk at flood-prone sites through targeted interventions throughout the catchment,...
Social pressure on alluvial plains and deltas is large, both from an economic point of view and from a nature conservation point of view. Gradually, flood risks increase with economic development, because the expected damage increases, and with higher dikes, because the flooding depth increases. Global change, changing social desires, but also changing views, require a revision of flood-risk ma...
This report is intended to be used by researchers working on decision support tools in flood risk management. It describes the construction of a GIS-based flood risk assessment tool and reviews each feature in turn, making up the hazard, vulnerability and risk interface of the tool. Feedback from emergency professionals is presented in a companion report, alongside some practical recommendation...
This paper discusses some methodological issues characterizing the development of a short-cut methodology for Na-Tech risk assessment, with particular reference to the integration between flood – and technological – related hazards. Actually, flood events can involve industrial areas increasing the level of risk for people, especially in densely populated areas where major hazard factories and ...
