“…According to the extreme value theory, the behavior of these maxima can generally be described by one of the three extreme value distributions: Gumbel, Fréchet, and Weibull. The generalized extreme value (GEV) distribution, a single parametric family, represents the aforementioned three extreme distributions [ Khaliq et al ., ; Agilan and Umamahesh , ]. The cumulative distribution function of the GEV is described as [ Koutsoyiannis , ; Hosking and Wallis , ] follows: FnormalGnormalEnormalV()xtrue|μ,σ,ξ=normalexp[]prefix−1+ξxμσprefix−1true/ξ. …”

“…The literature on stationary‐based risk assessment of precipitation intensity shows a variety of approaches in the context of univariate and multivariate processing [ Veneziano and Yoon , ; Endreny and Imbeah , ; Blanchet et al ., ; Bezak et al ., ]. Very few publications discuss the incorporation of climate‐related nonstationarity in IDF curves [ Agilan and Umamahesh , ; Cheng and AghaKouchak , ; Lima et al ., ]. The present study develops a flexible time‐varying risk framework using Bayesian techniques to model different complex forms of nonstationarity.…”

“…According to National Research Council [36], these changes in climate are the result of increased emissions of greenhouse gases like carbon dioxide (CO2) from the burning of fossil fuels and destruction of tropical forests. As observed by Agilan and Umamehesh [1], nowadays it is widely recognized that global climate changes are intensifying extreme rainfall events and creating a non-stationary component in the extreme rainfall time series.…”

“…Zamani et al [20] showed that monthly, seasonal and annual flow discharges have decreasing [27] utilized SDSM and A2 and B2 scenarios in Wami-Ruvu River Basin of Tanzania and showed that rainfall and maximum temperature will increase and minimum temperature will reduce; Lima et al [28] uses of GCMs and the traditional Generalized Extreme Value (GEV) distribution for generation of Intensity-Duration-Frequency (IDF) curves in Korea and they showed that intensity of rainfalls with short durations and long return periods will increase in future; Agilan & Umamahesh [29] uses of GCMs and 'K' Nearest Neighbor (KNN) weather generator downscaling method in the Hyderabad city of India for generation of IDF curves and they showed that intensity of rainfalls will increase in future; Mailhot et al [30] Base Function (RBF) ANN for downscaling and concluded that rainfall intensity will increase for return periods less than 2.33 years while it will decrease for return periods more than 2.33 years.
