dc.description.abstractIn 2007, the Centre for Global Archaeological Research (CGAR) Universiti Sains Malaysia (USM) has discovered existence historical object in Sungai Batu, Kedah. Based on excavation result, known that Sungai Batu was declare as an early civilization in Southeast Asia. This triggering archaeologist to extend the excavation site. Try and error methods by excavate random area is time consuming, failure to find buried object and can disturb the historical evidence. This study used 2-D resistivity imaging and seismic refraction methods to determine and validate the resistivity and velocity value at Sungai Batu and to identify and characterize subsurface geology and geomorphology profile Sungai Batu ancient river system. A total of thirty, 2-D resistivity imaging survey lines using Pole-Dipole array for maximum depth penetration and nine seismic refraction survey lines were conducted at the study area. Four of the lines were correlated and validated with existing on-site borehole to identify soil type. The validated values applied to the remaining survey lines which no borehole record to map the subsurface of the study area. Based on the results, Sungai Batu area consist of clay with resistivity value of 7-26 Ω.m and velocity value of 717-1607 m/s; sandy clay with resistivity value of 6-265 Ω.m and velocity value of 1004-1901 m/s; while bedrock/hard layer was identified with resistivity value of more than 669 Ω.m and velocity value of more than 2052 m/s. Boundary between clay/sandy clay with shale was identify with resistivity value of 314 Ω.m and velocity value of 1822 m/s. Subsurface geology and geomorphology profile of Sungai Batu area is characterized by recent alluvium (clay and sandy clay) thickness and bedrock topography.en_US
