Abstract: Ground Water Levels is the most important or needed in Primary Sector, Industrial Sector and Service Sector also, especially Agricultural Sector its play a vital/crucial role. Present paper deals with the application of ?Time Series Analysis? to analyze and predict Ground Water Levels (GWLs) in Anantapuramu district based on the data collected from January 2001 to November 2017. Through with Ratio to Trend Method, for the purpose of analysis the district is divided into five Zones or Revenue Divisions (RD) namely, 1. Anantapuramu RD 2. Penukonda RD 3. Kadiri RD 4. Kalyandurg RD 5. Dharmavaram RD. We have calculated for the values of the Seasonal Indices (S.I) and compared among them by using the data. Further, validation of the fitted method identified the best suitable Zone. In the present paper we analyze the data collected and identified Seasonal effects for Ground Water Levels and conclusions are drawn based on the results obtained.
