Abstract
This paper describes the results of a ground water potentiality assessment and its importance in the field of trenchless technology. Water plays a vital role in the development as well as for depletion of any activity in the area . Thus, the availability of surface and ground water governs the process of planning & development of any activity. The surface water resources are inadequate to fulfill the water demand. Productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly developed through exploration. Keeping this in view, the present study attempts to identify and understand groundwater potential zones of the study area using GIS. The methodology includes the construction of groundwater potentiality map using Geographical Information System (GIS) to protect the groundwater resources in the study area and to formulate recommendations to reduce the water scarcity. The ground water potentiality of the area has been assessed through integration of the relevant layers which include geomorphology, geology, slope and land use/ land cover, in ArcGIS environment. Criteria for GIS analysis have been defined on the basis of ground water conditions and appropriate weightage has been assigned to each information layer according to relative contribution towards the desired output. The ground water potential zones map generated through this model was verified with the yield data to ascertain the validity of the model developed and to find its corresponding influence in the subsurface constructions.
