Introduction Adaptation to climate change is one of the main concerns for cities in deltaic areas. For a country such as the Netherlands where two thirds of the land are located under sea level, reliability of the flood defence system is a top priority. Flood defences are exposed to different deterioration processes (also known as failure mechanisms) which might compromise the water retaining c...
The rainfall input is one of the main factors influencing the magnitude of the runoff response during a flood event. Its temporal and spatial distribution significantly contributes to the formation of hydrograph shape, peak discharge and flood volume. a novel approach to the evaluation of the role of the temporal rainfall pattern of hydrograph is presented in this contribution. The methodology ...
About 90 percent of natural calamities that occur in the world are related to climatic factors and among them storms after flood include 30 percent of these calamities. This phenomenon is one of the most perilous natural calamities that has a climatic origin and imposes irreparable financial and physical losses every year. Sistan which is one of the stormiest areas is located at the s...
Statistical dependence among random hydraulic variables generally stem from a common meteorological cause. Usually, this dependence increases the probability of occurrence of floods. Therefore, in many (potential) applications in flood risk analysis there is a need for techniques that properly describe the statistical dependence among random variables. This study makes an inventory of existing ...
Millennial- and multi-centennial scale climate variability during the Holocene has been well documented, but its impact on the distribution and timing of extreme river floods has yet to be established. Here we present a meta-analysis of more than 2000 radiometrically dated flood units to reconstruct centennial-scale Holocene flood episodes in Europe and North Africa. Our data analysis shows a g...
Understanding the hydro-meteorological processes that control flash flooding is extremely important from both scientific and societal perspectives. On the one hand, flash floods rank highly among natural disasters in terms of the number of people affected and the number of fatalities. The potential for flash flood casualties and damage is increasing in many parts of the world due to the social ...
Flood risk assessment is an important tool for urban planning, land development, and hydrological analysis. The flood risks are very high in arid countries due to the nature of rainfall resulting from thunderstorms cover, which comprises mostly dry soil. Several methods have been used assess risk, depending on various factors that affect likelihood occurrence. However, selection these weight as...
Local scouring around the bridges piers has always been considered as a problem, especially in rivers. If we do not take the necessary actions to avoid the occurrence of this phenomenon or to reduce its influence, then the bridge's piers will be destroyed. Placing the bridge piers' foundation far from the earth's surface will turn out in a plan which is not economic at all. Experimental studies...
BACKGROUND Foot injury was common as a result of the Bangkok flood of 2011. In the future, this type of injury should be prevented to lessen the burden during a disaster. OBJECTIVES The study was performed to ascertain what type of footwear is appropriate for volunteer rescue workers during a flood. MATERIAL AND METHODS The study was carried out during the flood in November 2011 at Siriraj ...
The concentrations of dissolved and particulate polycyclic aromatic hydrocarbons (PAHs) were monitored in waters of the Rhône River (France) every fortnight for a full calendar year, from June 1994 to May 1995. All flood events occurring over the course of the experiment were sampled at higher frequency to better quantify the impact of these extreme hydrological episodes on the annual export of...
