Groundwater (GW) trend analysis provides an early warning system for changes in water table caused by climatic conditions or in response to human activities such as water withdrawal. This analysis investigates the pattern and trends of the seasonal groundwater level data of Arpa River Basin in Bilaspur district, Chhattisgarh for the period from 1984 to 2015. A study was under taken for identifying the trends in pre- and post-monsoon groundwater levels using non parametric Mann-Kendall test and Sen's slope estimator for time series modelling and forecasting of pre- and postmonsoon groundwater. |
