2D TO 3D RESISTIVITY IMAGING ON DETERMINIG THE VOLUME OF SINKHOLE : STUDY CASE IN KAMPAR

A geophysical study was conducted at area Mukim Kampar using 2D Electrical
Resistivity Technique (ERT) to study subsurface analysis. The study area is in the Kinta
Limestone Formation. The study area lies within the Kinta limestone formation which
is characterized by weak soils overlying limestone bedrock with karstic features such
as pinnacles, solution channels, cavities, cliffs, overhangs and steep depression amidst
rock plateau. The objective of this subsurface analysis is to study the subsurface of
limestone features using Electricity Resistivity Imaging, to produce resistivity map
(isoelectric) at the study area and to generate 3D model at the subsurface limestone
features.
