Without ground water, humanity cannot survive in this world. Groundwater is significant for farming, household and industrial needs. Insufficient of groundwater result the major economic setback of our nation. In India, especially in Tamilnadu groundwater were extracted more and to a greater extent and most of the studies and report state that, most of the safe groundwater zone area converted into the over-exploited and critical zone area. The public in the Palani Taluk largely depends upon groundwater for urban and agricultural needs. Therefore, monitoring the groundwater level and its fluctuation is important, which helps to categorise the review region based on the groundwater level. The objective of the research is to recognise groundwater fluctuation zones based on pre-monsoon and post monsoon season in Palani Taluk, to achieve this, GIS Technology got unique and advanced tools to evaluating the enormous quantity of various spatial and characteristic records.
