Climate change due to anthropogenic greenhouse gas emissions is expected to increase the frequency and intensity of precipitation events, which is likely to affect the probability of flooding into the future. In this paper we use river flow simulations from nine global hydrology and land surface models to explore uncertainties in the potential impacts of climate change on flood hazard at global...

Abstract Flood frequency estimation forms the basis for engineering design of hydraulic structures, including bridges and culverts, local regional development planning, flood insurance. In United States, Water Resources Council recommends using Log-Pearson Type III (LP3) distribution as a standard use with annual peak flow data. However, researchers have argued more than one streamflow value in...

To design hydraulic structures, predicting the discharge of flood is necessary, the main cause lies in failure that may occur in downstream. Most hydraulic structures were destructed because of the lack of resistance against floods with flow rate more than design flood, so selecting design flood is one of important decisions should be made as an effective factor accompany with other hydrologic ...

Flood frequency analysis (FFA) is a form of risk analysis, yet a risk analysis of the activity of FFA itself is rarely undertaken. The recent literature of FFA has been characterized by: (1) a proliferation of mathematical models, lacking theoretical hydrologic justification, but used to extrapolate the return periods of floods beyond the gauged record; (2) official mandating of particular mode...
