Derived flood frequency distribution for negatively correlated rainfall intensity and duration

Regional rainfall and flood frequency analysis for Sicily using the two component extreme value distribution

This paper first presents a duration-dependent hypothesis regarding the parameters of the two component extreme value (TCEV) distribution and proposes a simple model to obtain the rainfall depthduration relationship both at ungauged sites and at short record gauged sites in the Sicilian region. Then, by using the annual maximum peak flood and the annual maximum mean daily discharge recorded in ...

Intensity-Duration-Frequency (IDF) rainfall curves, for data series and climate projection in African cities

Changes in the hydrologic cycle due to increase in greenhouse gases cause variations in intensity, duration, and frequency of precipitation events. Quantifying the potential effects of climate change and adapting to them is one way to reduce urban vulnerability. Since rainfall characteristics are often used to design water structures, reviewing and updating rainfall characteristics (i.e., Inten...

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...
