TWO-PARAMETER GAMMA DISTRIBUTION AND LOG NORMAL DISTRIBUTION FOR DERIVATION OF SYNTHETIC UNIT HYDROGRAPH

Journal of Engineering, 2011
Most available methods for unit hydrographs (SUH) derivation involve manual, subjective fitting of a hydrograph through a few data points. The use of probability distributions for the derivation of synthetic hydrographs had received much attention ...

The A Priori Procedure for Estimating the Mean in Both Log-Normal and Gamma Populations and Robustness for Assumption Violations

Methodology, 2022
Although the literature on the a priori procedure, designed to help researchers determine the sample sizes they should use in their substantive research, is expanding rapidly, there are two important limitations.

Bayesian inference for quantiles of the log‐normal distribution

Biometrical Journal, 2020
AbstractThe log‐normal distribution is very popular for modeling positive right‐skewed data and represents a common distributional assumption in many environmental applications. Here we consider the estimation of quantiles of this distribution from a Bayesian perspective. We show that the prior on the variance of the log of the variable is relevant for

Investigating the Effect of Distribution Function and Potential Evapotranspiration Assessment Method in Determining Reconnaissance Drought Index [PDF]

علوم و مهندسی آبیاری, 1970
Iran is located in arid and semi-arid regions in the world and therefore, drought monitoring has an important role in there. Drought assessment is conventionally based on drought indices such as Reconnaissance Drought Index (RDI).

An Alternative to the Log-Skew-Normal Distribution: Properties, Inference, and an Application to Air Pollutant Concentrations

Mathematics, 2022
In this study, we consider an alternative to the log-skew-normal distribution. It is called the modified log-skew-normal distribution and introduces greater flexibility in the skewness and kurtosis parameters.

Maximum discharge and probable rainfall at Aiuruoca basin, Minas Gerais State

Revista Ambiente & Água, 2014
Research on rainfall and annual daily maximum discharge rates is essential to support decisions during the design of hydraulic structures. This study tested the adequacy of probability functions to predict the probable rainfall and discharge rates of the
