Abstract
Sediment movement from land or sediment load, into rivers and settle at the river mouth
or coastal area can create enormous effect on environment and any activity related.
Thereby, the sediment load study is needed to understand better on the sedimentation
and erosion process at a catchment. In this study, Arc View Soil and Water Assessment
Tool (ArcSW AT) model had been used to estimate sediment load at the Terengganu
River catchment (approximately 440000 hectares). For better prediction, there are
several parameters that had been taken consideration such as rainfall, soil type, land
use, surface elevation, and river network of the catchment. All the weather data ranged
from 1980 until 2010 daily data were obtained from Drainage and Irrigation
Department (DID) of Malaysia and Meteorology Department (MET) Malaysia. In-situ
SSC at 2 stations: Station 1 at river mouth and Station 2 at upper stream had been
analyzed (2.2.2015 to 5.2.2015) in order to test correlation relationship with simulated
sediment load result from ArcSWAT.
