IJERTV10IS070104 Construction of water table contour map and Geohydrological Studies in Pathanamthitta using GIS techniques Ashna Beegum , Simi Monachen , Sandra K Shaji , Anamika Chandra, Vishnu K Pathanamthitta is a developing city in Kerala, India. Ground water is a major source of water supply for the town which is reflected by regular extraction of ground water through ever increasing no. of municipal industry and private bore wells. Water table contour map represent lines of equal elevation. Creation of a water table contour map will help in a variety of ways. Through this points with equal ground water levels can be easily identified. QGIS software helps in creating the map. Water levels from wells represent the ground water level in an area. Different zones can be identified from a water table contour map. Hydrogeology makes use of ground water contour maps in order to evaluate an aquifer. These maps indicate lines with equal ground water levels based on a reference level (masl). A ground water contour map provides important information about ground water movement and flow directions. Different regions facing water scarcity will be identified. The groundwater potential zones are identified to the help of study the geographical factors and groundwater availability.
