The use of engineering risk analysis and multi-objective decision-making under risk are considered as tools for floodplain management and extreme flood protection. Distinction is made between (a) the catchment or large scale planning and (b) the local or small-scale design of protection measures. After defining the risk of flooding at different scales and specifying the multiple criteria that m...

Floods have caused major losses and damages to people, infrastructure, the environment. This study aims assess risk perception of households prone riverine flash floods perceived infrastructure livelihoods. Data were collected from 382 through a questionnaire survey analyzed using chi-squared t-tests. Overall, was higher for floods. Similarly, ‘flood coping capacities’, ‘livelihood disruption’,...

Flash floods are typically associated with short, high-intensity and extreme rain-storms, they characterized by short response time severely impact damage communities in different areas China. In order to scientifically assess the risks of flash floods, this paper takes Hubei Province as an example carry out risk assessment. Based on Pearson correlation coefficient principal component analysis ...

Flash floods are highly variable phenomena in both time and space. Therefore, tools with the potential to provide early warning are needed to analyse them. In Europe, flash floods often occur on small catchments; it has already been shown that the spatial variability of rainfall has a great impact on the catchment response. The aim of this paper is to use a coupled hydrological-hydraulic model ...

Satellite radar and radiometer data show that subtropical South America has the world’s deepest convective storms, robust mesoscale convective systems, and very frequent large hail. We determine severe weather characteristics for the most intense precipitation features seen by satellite in this region. In summer, hail and lightning concentrate over the foothills of western Argentina. Lightning ...

OBJECTIVE To evaluate effectiveness of a community-based preparedness program for flash floods. DESIGN A controlled community intervention trial with preassessment and postassessment. SETTING Fifteen intervention villages and 16 control villages in Golestan province of Iran. PARTICIPANTS People more than six years of age. INTERVENTION Intervention program consisted assembling Village Di...

The error in satellite precipitation-driven complex terrain flood simulations is characterized in this study for eight different global satellite products and 128 flood events over the Eastern Italian Alps. The flood events are grouped according to two flood types: rain floods and flash floods. The satellite precipitation products and runoff simulations are evaluated based on systematic and ran...

Karst flash flooding, identified as one of the hazards in karst terrains, is directly linked to the structure and hydraulic properties of karst aquifers. Due to the characteristics of flow within karst aquifers, characterized by a dual flow – diffuse flow within fissured limestone and conduit flow within karst conduits networks – flash flooding may be important in volume and dynamics. Such phen...

The flash flood registered in November 1997 the city of Badajoz (Spain) basin Rivillas river is analysed by means numerical code Iber+. This event constitutes one most destructive flash-floods an urban area Iberian Peninsula. Starting from precipitation data obtained rain stations, runoff entire was simulated to obtain discharge Badajoz. maps with Iber+ reproduce accurately field during actual ...
