Regional frequency analysis of maximum daily rainfalls using TL-Moment approach

Analyzing rainfalls data are important in order to obtain the probability distribution of flood. The main aim of the study is to perform regional frequency analysis of maximum daily rainfalls measured over stations in Selangor and Kuala Lumpur by using the TL-moment method with t = 0, t = 1 and t =...
