Kertas ini bertujuan menjalankan kajian analisis frekuensi banjir serantau bagi aliran sungai tahunan maksimum di Semananjung Malaysia menggunakan pendekatan LQ–momen. Kaedah LQ–momen dibangunkan untuk digunakan dalam analisis frekuensi banjir serantau bagi mengukur keserasian data, kehomogenan rantau dan pengujian pemadanan bagi mengenal pasti taburan serantau terbaik. Algoritma Gustafson–Kessel (GK) diperkenalkan dalam mengenal pasti rantau homogen Semenanjung Malaysia, dan telah menghasilkan enam rantau homogen yang diuji menggunakan kaedah LQ–momen. Hasil kajian ini menyokong bahawa kaedah LQ–momen secara umumnya berupaya, ringkas dan teguh. Ini membuatkan ianya sebagai alternatif pilihan untuk digunakan dalam analisis frekuensi banjir serantau. Kata kunci: LQ–momen; L–momen; Gustafson–Kessel; analisis frekuensi banjir serantau; pengujian kesesuaian This paper aims to perform regional flood frequency analysis of the annual flood series in Peninsular Malaysia by using LQ–moment approach. The LQ–moments method was developed to use for regional flood frequency analysis in measuring discordancy, regional homogeneity, and goodness–of–fit test to identify the best regional parent distribution. The Gustafson–Kessel algorithm (GK) is presented to identify the homogenous regions in Peninsular Malaysia and produced six acceptably homogeneous regions that had been tested by the method of LQ–moments. The results shown in this study strongly support the method of LQ–moments in terms of good performance, simplicity and robustness. This made it an attractive option for using in the regional flood frequency analysis. Key words: LQ–moment; L–moments; Gustafson–Kessel; regional flood frequency analysis; goodnessof–fit testDownloads
