Chandan Kumar Pandit

Abstract: This paper presents an analysis of the water level of Hatia Dam, Ranchi, based on historical data from 2009 to 2020. The study identifies a positive trend in water levels during several months (i.e. for February, March, April, May, July, November, December) and seasons (i.e. for Summer, Monsoon, Post-Monsoon), with significant correlations observed between the water level and monsoon rainfall. Temperature, however, shows no significant correlation with water levels. The water level of Hatia Dam reaches its peak during the post-monsoon season meters and the lowest water level is observed during summer season. The ARIMA (0,1,1) model was employed for forecasting, predicting that the water level will reach 590.131 meters by 2030.
