Description
Summary:Water is a major issue that faced by the settlement area in most country around the world. Moreover, if the settlement is located in metropolis city. Based on those reasons, the authors triggered to conduct the study regarding the identification of potential aquifer. The study carried out in Blang Bintang (Aceh Besar) by utilized 2D resistivity method. The 2D resistivity survey lines were conducted with 5 m minimum electrode spacing using pole-dipole array, and the results validated with existing borehole record. The bore-log identified aquifer zone located between sandy clay and clay with depth of 56-67 m. The 2D resistivity results shows the aquifer layer located at depth of 55-70 m with resistivity value of 30-45 Ωm. Both data are significantly consistent. It can be concluded that the aquifer can be identify using 2D resistivity imaging using any available array, but the resistivity values vary depend on their geology setting.
