General Geology and Surface Investigation of Groundwater Potential Zone Using Geological Mapping and Geographical Information System (Gis) at Telaga Bijih area, Tanah Merah, Kelantan.

Identifying a good site for groundwater exploration in hard rock terrain is a challenging task. In hard rocks, groundwater occur in secondary porosity developed due to weathering, fracturing, faulting, etc., which is highly variable and varies sharply within very short distances, contributing to near-surface aquifer. In such situations topographic, hydrogeological and geomorphological features provide useful clues for the selection of suitable sites. The study area lies between latitude 5° 45' 10.508 N and 5° 47' 53.309" N and longitude 101° 56' 29.001" E and 101° 59' 12.249" E. The research is focusing on the surface investigation of groundwater potential zone using geological mapping and Geographical Information System (GIS) in and around Telaga Bijih Area, Tanah Merah, Kelantan. Initially based on the satellite imageries, topographical, geomorphological and hydrogeological inference promising zones were demarcated in hard rock areas of in and around Telaga Bijih village. For this purpose, the essential thematic layers such as lineament density, lithology, drainage density, and slope density were generated using Geographic Information System (GIS) application to generate groundwater potential zonation map. The final map of groundwater potential will showed the potential zones in the study area. Based on hydrogeomorphological, geological and lineament mapping, the study area has qualitatively been categorized into five condition it found that the most concentration of groundwater zones having high potential are situated near to the lineament zones in study area.
