Determination of sediment load chenges (1983-2010) at Terengganu river catchment using remote sensing and goagraphic information system (GIS) technology
(Universiti Malaysia Terengganu, 2015) Chong, Wei Sheng
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.
