Suspended sediment concentration mapping at temenggor lake using landsat-8 tm data

Abstract

Sediment is a natural occurring material that is broken down by the process of climate and soil erosion whereby transported by the action of wind, water or by the force of gravity acting on the particles. From the satellite data, the total concentration of suspended sediment in the inland water able to be mapped using remote sensing technique processing. Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and therefore not comparable to in-situ observations. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on earth by means of propagated signals. In this study, Landsat-8 TM satellite image is used in determining the concentration of suspended sediment at Temenggor Lake, Perak. Remote sensing techniques is used in processing and analysing the correlation of data sampling and satellite data, respectively. This study indicates that band 2 of Landsat-8 TM able to show the good correlation from polynomial equation at R2 = 0.54 in determining the suspended sediment concentration at Temenggor Lake. This study concluded that Landsat-8 TM is able to map the concentration of suspended sediment in inland water at Temenggor Lake.
