Floods through inundated urban environments constitute a hazard to the population and infrastructure. A series of field measurements were performed in an inundated section of the City of Brisbane (Australia) during a major flood in January 2011. Using an acoustic Doppler velocimeter (ADV), detailed velocity and suspended sediment concentration measurements were conducted about the peak of the f...

In the present paper, COSMO-SkyMed high-resolution data acquired on the southern Basilicata region (Italy) are used for flood hazard monitoring. We concentrate on the flood event of Nov. 2-4, 2010, for which multi-temporal SAR data were available over the Bradano River downstream area in the same acquisition geometry, which allows interferometric processing. SAR intensity data analysis of two a...

This paper examines the effects of urbanization on the flood hazard in semi-arid/arid southern California using traditional hydrograph, frequency-magnitude and statistical analysis augmented with GIS-based variable parameterizations and visualizations. It was found that the peak flood discharges were significantly increased in urban watersheds in conjunction with increasing mean baseflow in the...

Damage assessments of natural hazards supply crucial information to decision support and policy development in the fields of natural hazard management and adaptation planning to climate change. Specifically, the estimation of economic flood damage is gaining greater importance as flood risk management is becoming the dominant approach of flood control policies throughout Europe. This paper revi...

Conventionally flood mapping typically includes only a static water level (e.g. peak of a storm tide) in coastal flood inundation events. Additional factors become increasingly important when increased water-level thresholds are met during the combination of a storm tide and increased mean sea level. This research incorporates factors such as wave overtopping and river flow in a range of flood ...

In March 2014, Congress passed legislation to halt discounted flood insurance premiums from increasing to full-risk levels. The rate hike was authorized two years earlier by the Biggert-Waters Act to address the National Flood Insurance Program’s structurally induced $24 billion debt. The recent developments highlight the tension between risk-based premium and affordability of flood insurance f...

El Niño and La Niña events, the extremes of ENSO climate variability, influence river flow and flooding at the global scale. Estimates of the historical probability of extreme (high or low) precipitation are used to provide vital information on the likelihood of adverse impacts during extreme ENSO events. However, the nonlinearity between precipitation and flood magnitude motivates the need for...

The field of hazard function analysis (HFA) involves a probabilistic assessment of the ‘‘time to failure’’ or ‘‘return period,’’ T, of an event of interest. HFA is used in epidemiology, manufacturing, medicine, actuarial statistics, reliability engineering, economics, and elsewhere. For a stationary process, the probability distribution function (pdf) of the return period always follows an expo...

Flood disaster is considered as a major natural hazard due to its devastatingeffects on the affected areas. Determining the flood vulnerable areas is important fordecision makers in order to perform planning and management activities. GeographicalInformation System (GIS) is integrated with Multi Criteria Decision Analysis (MCDA)used to analyze the flood vulnerable areas. The aim of this researc...
