Geology and identification of potential groundwater location using Eri Of Dabong, Kelantan

The study area is located in Dabong that belong to Kuala Krai district which is developing and increasing in population day by day. As the growth population increases, problems such as depletion of water resources and lack of clean water could be arises in time. In future, groundwater is important as an alternate source for backup plan to overcome the problem of decreasing sources of clean surface water. Keep in view, the present study focus on update the geological map on 1: 25,000 scale and to identify the potential groundwater location using Electrical Resistivity Imaging (ERI) method. Geological mapping and geophysical survey were conducted and rock samples were collected from lithology, and also structural data, were collected during the fieldwork. Three survey lines were established during the geophysical survey at three different locations. For location 1, the survey line follows Pole-dipole electrode configuration array while another two locations follow Schlumberger electrode configuration arrays and all the data from all locations were recorded using ABEM Terrameter LS 1, then the data is processed by using RES2DINV software. The results show that potential groundwater location existing in the alluvium for survey line 2 and fracture zones for survey line 1 and 3. The geological mapping and geophysical survey is a good combination to identify the potentially groundwater locations in the study area
