Study of rainfall-runoff relationship using hydrological modelling system (HEC-HMS) for Johor river, Malaysia

This study focused more in flood estimation model for Johor River in Kota Tinggi watershed, Malaysia using HEC-HMS (Hydrological Modeling System). HEC-HMS is necessary tool for analyzing and simulating rainfall and runoff process. In this study, HEC-HMS version 3.5 is used to simulate stream flow fo...
