A short cut methodology for flood-technological risk assessment
نویسندگان
چکیده
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 flooding areas overlap. In spite of its potential high relevance, risk from industrial accidents triggered by floods has so far received little attention.

Determining tropical cyclone inland flooding loss on a large scale through a new flood peak ratio-based methodology
In recent years, the United States has been severely affected by numerous tropical cyclones (TCs) which have caused massive damages. While media attention mainly focuses on coastal losses from storm surge, these TCs have inflicted significant devastation inland as well. Yet, little is known about the relationship between TC-related inland flooding and economic losses. Here we introduce a novel ...

Flash floods are considered to be one the worst kind of hazard. They are characterized by their suddenness, rarity, small scale, heavy rain and peak discharge, unpredictable, fast and violent movement. It has severe effects on human society in the form life losses, damages to property, roads, communication and on natural settings. Advances in hydrology, meteorology, engineering, using of GIS an...
متن کاملNational-scale assessment of current and future flood risk in England and Wales
In recent years, through the availability of remotely sensed data and other national datasets, it has become possible to conduct national-scale flood risk assessment in the England and Wales. The results of this type of risk analysis can be used to inform policy-making and prioritisation of resources for flood management. It can form the starting point for more detailed strategic and local-scal...
متن کاملFuzzy approach to analysis of flood risk based on variable fuzzy sets and improved information diffusion methods
The predictive analysis of natural disasters and their consequences is challenging because of uncertainties and incomplete data. The present article studies the use of variable fuzzy sets (VFS) and improved information diffusion method (IIDM) to construct a composite method. The proposed method aims to integrate multiple factors and quantification of uncertainties within a consistent system for...
متن کاملFlood Risk Impact Factor for Comparatively Evaluating the Main Causes that Contribute to Flood Risk in Urban Drainage Areas
Among the various factors that contribute to flood risk, heavy storms, inadequate storm drainage systems, and the concentration of population and assets have usually been considered to be fundamental factors affecting flood damage. Climate change is also a real threat, bringing heavier and more frequent storms. This study presents a methodology for comparatively evaluating the impact of the flo...
