STUDY ON GEOMORPHOLOGY AND YOUNG QUATERNARY STRATIGRAPHY OF PERAK RIVER AND COASTAL PLAIN AREAS

This study focuses on geomorphology and Young Quaternary stratigraphy of the Perak River and its coastal areas. The Perak River is located on the west flank of Peninsular Malaysia. It can be divided into four geographic regions; lower and upper parts for both of the upstream and coastal areas. The channel pattern occurred in this area includes the straight-braided and meandering. The river flow changes it direction from north to south before drifted easterly to the west at Teluk Intan. There are five main evolutions occurred in the downstream of Perak River. The interpretation of satellite images and the compilation of the borehole data have been used to investigate the sedimentation and Young Quaternary stratigraphy of the coastal areas around Perak River.
