Abstract
The aim of this study is to use two geophysical methods and collaborate with borehole profile in the assessment of subsurface condition and types of material. These include electrical resistivity and seismic refraction surveys. Assessment of subsurface includes the measurement of depth to bedrock, and identification of the presence of core boulder, weak zone, and cracks. Electrical resistivity survey is done by measuring electrical conductivity values in order to distinguish different condition of soil. On the other hand, seismic refraction survey measures velocity of wave produced to evaluate depth of subsurface layers.
