Every year, flood disasters are responsible for widespread destruction and loss of human life. Remote sensing data are capable of providing valuable, synoptic coverage of flood events but are not always available because of satellite revisit limitations, obstructions from cloud cover or vegetation canopy, or expense. In addition, knowledge of road accessibility is imperative during all phases o...

In the United States, insurance against flood hazard (inland flooding or storm surge from hurricanes) has been provided mainly through the National Flood Insurance Program (NFIP) since 1968. The NFIP covers $1.23 trillion of assets today. This article provides the first analysis of flood insurance tenure ever undertaken: that is, the number of years that people keep their flood insurance policy...

Facing rising sea levels, increasing peak discharges of the rivers and intensification of rainstorms due to climate change; the subsidence of land; development of urbanization; and the growth of population, flood risks continue to be the prime issue to the Netherlands. As the frequency and severity of floods increase, the reconsideration of current flood defense strategies is imperative. This p...

Dongting Lake, the second largest freshwater lake in China, is well known for its rapid seasonal fluctuations in inundation extents in the middle reach of the Yangtze River, and it is also the lake most affected by the Three Gorges Project. Significant inter-annual and seasonal variations in flood inundations were observed from Moderate Resolution Imaging Spectroradiometer (MODIS) time-series i...

Large-scale floods have the potential to generate substantial economic losses. Within Europe, governments have dealt with these losses in different ways, which may or may not have enhanced adaptability of their societies. In this research we develop a classification of insurance and compensation systems to deal with losses from floods. We suggest that, from the perspective of adaptive capacity ...

The paper presents the state-of-the-art in flood forecasting and simulation applied to a river flood analysis and risk prediction. Different water flow forecasting and river simulation models are analysed. An advanced river flood forecasting and modelling approach developed within the ongoing project INFROM is described. It provides an integrated procedure for river flow forecasting and simulat...

BACKGROUND Although numerous studies have indicated that exposure to natural disasters may increase survivors' risk of post-traumatic stress disorder (PTSD) and anxiety, studies focusing on the long-term psychological outcomes of flood survivors are limited. Thus, this study aimed to estimate the prevalence of PTSD and anxiety among flood survivors 17 years after the 1998 Dongting Lake flood an...

The accurate estimation of flood risk depends on, among other factors, a correct delineation the floodable area and its associated hydrodynamic parameters. This characterization becomes fundamental in hazard analyses that are carried out urban areas. To achieve this objective, it is necessary to have topography, both inside riverbed (bathymetry) outside it. Outside riverbed, LiDAR data led an i...

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...

In this article we investigate the complex relationship between environmental risk, poverty, and vulnerability in a case study carried out in one of the poorest and most flood-prone countries in the world, focusing on household and community vulnerability and adaptive coping mechanisms. Based upon the steadily growing amount of literature in this field we develop and test our own analytical mod...
