Comparison of Estimators of Gumbel Distribution for Assessment of Seasonal and Annual Rainfall

Comparison of Estimators of Gumbel Distribution for Assessment of Seasonal and Annual Rainfall Estimation of seasonal and annual rainfall for a river basin is of importance in planning and management of water resources projects. This study illustrates the use of six different parameter estimation methods for Gumbel distribution for assessment of seasonal and annual rainfall for Krishna and Godavari river basins. Goodness-of-Fit tests involving Anderson–Darling and Kolmogorov–Smirnov are used for checking the adequacy of fitting of Gumbel distribution to the recorded rainfall data. Model performance indicators such as correlation coefficient, model efficiency and root mean square error are used for the selection of suitable method for estimation of rainfall. The study shows that the probability weighted moments are better suited for determination of parameters of Gumbel distribution for assessment of seasonal and annual rainfall for Krishna and Godavari basins. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of The Institution of Engineers (India): Series A Springer Journals

Abstract

Estimation of seasonal and annual rainfall for a river basin is of importance in planning and management of water resources projects. This study illustrates the use of six different parameter estimation methods for Gumbel distribution for assessment of seasonal and annual rainfall for Krishna and Godavari river basins. Goodness-of-Fit tests involving Anderson–Darling and Kolmogorov–Smirnov are used for checking the adequacy of fitting of Gumbel distribution to the recorded rainfall data. Model performance indicators such as correlation coefficient, model efficiency and root mean square error are used for the selection of suitable method for estimation of rainfall. The study shows that the probability weighted moments are better suited for determination of parameters of Gumbel distribution for assessment of seasonal and annual rainfall for Krishna and Godavari basins.
