Abstract :
Earlier the authors worked on Trend effects and Seasonal effects on Ground Water Levels (GWLs) in Anantapuramu district, for the data collected from January 2001 to November 2017. While calculating trend values we have used different linear and non-linear models like, Straight line, Parabola, Exponential, Power curve models. Similarly to determine Seasonal effects we have used
- Simple Averages Method and
- Ratio to Trend Method.
Now we proceed to determine Seasonal effects through an improved method over Simple Averages and Ratio to Trend Method namely ‘Ratio to Moving Average Method’. Conclusions are drawn based on the results obtained.
