Relationship between ground penetrating radar [GPR] and dynamic cone penetrometer [DCP] for sinkhole detection / Fatin Anis Izzati Amiruddin

Sinkholes are a common occurrence that frequently occurs around the world. A sinkhole is an event where water flows into a low area and will cause sedimentation of the soil. Several methods effectively detect and resolve the problem, such as using Ground Penetrating Radar (GPR) and Dynamic Cone Penetrometer (DCP). The study's aims will show the relationship between GPR and DCP measurement that will be affected the result for the sinkhole detection. The objectives are to detect a sinkhole's existence and investigate the relationship between GPR and DCP in sinkhole detection. The study area proposed for this study is the University of Technology MARA (UiTM) Arau, located in Perlis. In this study, a GPR measurement will be conducted using one wavelength which is 800MHz. The methodology includes site selection and reconnaissance, data collecting, data processing, data interpretation, and result; fifth processes or phases are involved. The GPR radargram will be processed using Reflexw software, and the analysis process, which is statistical analysis, was performed on the test result collected from GPR and DCP. As the expected outcome, the strong relationship between GPR and DCP will be achieved due to the sinkhole presence.
