摘要

登嘉奴的集水区在季风季节一定会被洪水淹没。原因是气候变化增加了大部分河流的流量。使用ArSWAT2012进行的分析模拟了整个流域，结果证明有大约25个不同的子流域。每个子流域都有其独特的水文响应单元（HRU）特征。根据形态分类，这条河积累了大量的沉积物。通过模拟分析了1973年至2017年的产沙量和含沙量。这项研究比较了模拟结果，发现了流入和流出泥沙的滑动差异。泥沙浓度也随着丁加奴流域特别是河口的时间形态变化而变化。

SIMULATION OF SEDIMENT YIELD AND SUPPLY ON WATER FLOW IN DIFFERENT SUBBASINS OF TERENGGANU WATERSHED FROM 1973-2017

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.
