In Situ Flood Frequency Analysis Used for Water Resource Management in Kelantan River Basin

One of the most prevalent and traditional uses statistics in hydrology is flood frequency analysis. The can occur practically everywhere considered leading cause natural disaster death worldwide. This study aims to apply analysis Kelantan streamflow site identify optimal distribution that best fits data from goodness-of-fit test (GOF). Five distributions were applied this study; namely lognormal (LG), generalized extreme value (GEV), Pareto (GP), log-Pearson three (L3) logistic (GL) distribution. obtain parameter estimates. performance evaluation then performed utilizing GOF efficiency evaluations. results indicate GP possible function for determining annual peak flow at site.
