Drought Analysis in East Nusa Tenggara (Indonesia) Using Regional Frequency Analysis [PDF]
The Scientific World Journal, 2021 Drought is a condition of a shortage of water that has an impact on economic activity. This research studies the severe drought area in Indonesia using Regional Frequency Analysis (RFA), based on daily precipitation data recorded at nine stations.

Incorporating spatial dependence in regional frequency analysis. [PDF]
Water Resour Res, 2014 AbstractThe efficiency of regional frequency analysis (RFA) is undermined by intersite dependence, which is usually ignored in parameter estimation. We propose a spatial index flood model where marginal generalized extreme value distributions are joined by an extreme‐value copula characterized by a max‐stable process for the spatial dependence.

Optimal depth-based regional frequency analysis [PDF]
Hydrology and Earth System Sciences, 2013 Classical methods of regional frequency analysis (RFA) of hydrological variables face two drawbacks: (1) the restriction to a particular region which can lead to a loss of some information and (2) the definition of a region that generates a border effect.

Improved Regional Frequency Analysis of rainfall data
Weather and Climate Extremes, 2022 Rainfall are subject to local orography features and their intensities can be highly variable. In this context, identifying climatically coherent regions can greatly help interpreting rainfall patterns and improve the inference of return levels.

Regional Flood Frequency Analysis Using Computer Simulations [PDF]
International Journal of Advanced Engineering Research and Science, 2017 Different probability distribution methods were employed to determine the flood frequency analysis using computer simulations. Many probability distributions including Gumbel, lognormal, log-Pearson type iii, General Extreme value have been tried to fit the data. The length of record for most of the stations is over 10 years (chosen from 1956 0nwards).

Regional analysis of runoff thresholds behaviour in Southern Italy based on theoretically derived distributions [PDF]
Advances in Geosciences, 2011 The analysis of runoff thresholds and, more in general, the identification of main mechanisms of runoff generation controlling the flood frequency distribution is investigated, by means of theoretically derived flood frequency distributions, in the ...

Regional frequency analysis of extreme wind in Pakistan using robust estimation methods [PDF]
Scientific ReportsThe quantile estimates of extreme wind speed are needed for various areas of interest using regional frequency analysis (RFA) and extreme value theory. These calculations are crucial for the coding of wind speed. The data was taken from the NASA official

Quantifying Drought Characteristics in Complex Climate and Scarce Data Regions of Afghanistan
Geosciences, 2023 Droughts cause critical and major risk to ecosystems, agriculture, and social life. While attempts have been made globally to understand drought characteristics, data scarcity in developing countries often challenges detailed analysis, including climatic,
