Abstract

The Melantai River in Kluang, Johor, has experienced hydrological changes in recent years, such as changing rainfall patterns and runoff. These changes can be caused by urbanization, the changes in land use and climate. Extensive knowledge is needed on the characteristic of land use and soil type, and weather changes in the Melantai River watershed. This study uses SWAT+ to analyze the interactions between land use, soil type and rainfall-runoff processes under climate scenarios. Spatial and environmental data are processed through QGIS as a characterization tool to characterize land use and soil type, while the observed climate data (2010-2021) will be studied. Simulation of runoff volume and hydrological dynamics using SWAT+ gives an understanding of the changes in the water cycle that occur in the Melantai River. This study provides knowledge on land use and soil type of Melantai River watershed, swat+ model that has been adapted to the condition of Melantai river watershed, and evaluation of climate change impacts on rainfall pattern and runoff by simulated the Global Climate Data (GCM) from 2040-2060 using SSP5-8.5 scenario. The results of the study will be an useful tool for policy makers in developing effective water resources management and flood mitigation. this study emphasizes the important role of hydrological modeling in addressing complex problems in the watershed
