Estimating the flood frequency distribution
The goal of this study is to develop an objective methodology for estimating design floods, i.e. the flood peak discharge with return period T , at ungauged river catchments in Iceland. First, a regional flood frequency analysis is presented for estimating the T -year flood peak discharge with fixed duration D, Q(T,D), for poorly gauged and ungauged catchments. This is done by scaling a regiona...
متن کاملFlood frequency analysis: assumptions and alternatives
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...
متن کاملDetection and attribution of urbanization effect on flood extremes using nonstationary flood‐frequency models
Urbanization is found to have an impact on high flows in a urbanized catchmentThe use of point processes is advocated for trend detection and attributionThe use of process-related covariates gives a better representation of change.
متن کاملThe use of flood regime information in regional flood frequency analysis
Understanding the hydro-climatological controls on floods is fundamental for estimating flood frequency. The river flood regime is a reflection of a complex catchment hydrological response to flood producing processes. Hence, the catchment similarity in a flood regime is a feasible basis for identifying flood frequency pooling groups used in regional estimation of design events. This study desc...
