摘要
Surface water is critically important in supplying water to streams and wetlands, and in providing water for irrigation, manufacturing, electricity power and other uses and it is an important source of water supply especially in various regions in Malaysia and it become ever more important with an increasing population. However groundwater can be an alternative source of water to the ever increasing population. Groundwater is water located beneath the ground surface in soil pore spaces and in the fractures of lithologic water formations. This would provide alternative freshwater source. In order to determine the existence of usable groundwater for agriculture purposes in Marang Terengganu, 2-D resistivity imaging technique was utilized. Three lines were surveyed at the site. The 2-D resistivity imaging technique utilized the Pole dipole array because of relatively good horizontal coverage but it has significantly higher signal strength. The total length of the survey lines is 400 meters. Three lines were surveyed for groundwater delineation purpose. At Marang, the survey site shows the existence of groundwater. The maximum depth of investigations for the surveys is 125 meters. In general the results show that the subsurface is made up of sand and clay (resistivity value of less 100 ohmm) and sandstone with resistivity of more than 2000 ohmm in all the sections. This zone can be a source of groundwater.
