The catchment area of Terengganu has to be flooding during the monsoon season. The reason is climate change that increases water flow in most of the rivers. The analysis using ArSWAT2012 has simulated the whole watershed and the result as proven to have about 25 different sub-basins. Each sub-basin has its peculiar characteristics of Hydrologic Response Units (HRUs). Base on the morphological classification, the river has accumulated a lot of sediments. The sediment yield and concentration has been analyzed from 1973- 2017 through simulation. The study compared the simulations and found out the slide differences in the sediment loads that come in and the sediment that goes out. The sediment concentration also varies with the temporal morphological changes of the Terengganu watershed especially the river mouth.
