Abstract :

Agricultural drought becomes more appearance due to climate change and uncertain weather pattern. The current and continuing drought in many parts of the world, combined with ever increasing demands from both traditional and new water users, including municipal, industrial, agricultural and environmental needs, has impacted groundwater resources. Supplementary irrigation becomes important to overcome short term drought ensuring successful cultivation. Apart from obtaining the irrigation water from the traditional water sources (surface run off and rainfall) for irrigation, other alternative water source needs to be explored. The most feasible water source and relatively abundance is the ground water.Identify suitable location for shallow tube well development using electrical resistivity method has been extensively used. This method once of the surface geophysical methods can reduce risk and unnecessary costs by assisting in the siting of wells location. Technique based on resistivity can be used to interpret the characteristics of aquifer and thus to identify suitable location for tube well. The surveys were conducted at three different locations in Perak and Kelantan situated in Peninsular Malaysia which was mainly aluvial deposits lithology.The shallow tube well in quartenary aquifer into the ground will consider for groundwater identification.The resistivity values of highly discharge of groundwater approximately in ranges of 4.4Ωm to 20 Ωm with flowrate at range 45 m³/h to 47 m³/h.The depths of tube well were in between 9 to 24 m. The groundwater aquifers are found in saturated sand, coarse sand with some gravelly sand.
