Identifying potential groundwater is essential especially in the rural areas. However there is uncertainty in distinguishing groundwater from soil particles when using 2-D resistivity and Induced Polarization (IP) survey. Many researchers faced the problem of determining the exact location or missed the full capacity of the aquifer when drilling in the subsurface layers. Therefore the purpose of this study is to use the combination of resistivity and IP analysis to determine the potential groundwater in Machang Kelantan and to differentiate the saturated zones between aquifer and unconsolidated sediments. Four resistivity survey lines each 200 metre (m) long with 5 m electrode spacing using the pole-dipole array were set up. From the results of 2-D resistivity and IP survey the possible groundwater area in the subsurface can be indicated by low resistivity values ranging from 10 - 100 m (Ohm-m) and overlapped by low chargeability values ranging from 0 - 1 millisecond (msec). Alluvium which consists of sandy clay and sand has resistivity value of 500 - 2000 m and chargeability value of 3 - 10 msec. Fault and fracture in the subsurface may also indicate existence of an aquifer. The result of this study provides beneficial information on groundwater occurrence by differentiating aquifer to unconsolidated sediments.

Abstract

Identifying potential groundwater is essential especially in the rural areas. However there is uncertainty in distinguishing groundwater from soil particles when using 2-D resistivity and Induced Polarization (IP) survey. Many researchers faced the problem of determining the exact location or missed the full capacity of the aquifer when drilling in the subsurface layers. Therefore the purpose of this study is to use the combination of resistivity and IP analysis to determine the potential groundwater in Machang Kelantan and to differentiate the saturated zones between aquifer and unconsolidated sediments. Four resistivity survey lines each 200 metre (m) long with 5 m electrode spacing using the pole-dipole array were set up. From the results of 2-D resistivity and IP survey the possible groundwater area in the subsurface can be indicated by low resistivity values ranging from 10 - 100 m (Ohm-m) and overlapped by low chargeability values ranging from 0 - 1 millisecond (msec). Alluvium which consists of sandy clay and sand has resistivity value of 500 - 2000 m and chargeability value of 3 - 10 msec. Fault and fracture in the subsurface may also indicate existence of an aquifer. The result of this study provides beneficial information on groundwater occurrence by differentiating aquifer to unconsolidated sediments.
