Abstract
AbstractThe groundwater is a major source of water supply for both industrial and domestic purposes. Groundwater level is regularly declining at a faster rate due to its continuous withdrawal. The Indian state of Maharashtra has been in a constant state of drought due to the lower monsoon rainfall. Therefore the study has been done to assess the impact of rainfall and consequent change on the groundwater regime and surface water storage in the Sina Basin, Maharashtra using GIS and statistical analysis. Correlation methods were applied to investigate groundwater level response to rainfall, as well as its seasonal variations in the alluvial aquifer Sina basin. Data were collected from IMD for the year (1985–2009) of 9 stations. Trend analysis of rainfall was done using the Mann–Kendall test and a correlation was established between water level residual and moving average of rainfall. Results obtained by correlation analysis showed that the overall trend of rainfall in the Sina basin is increasing. Also, the results exhibited that the 2–year moving average of the annual rainfall of different stations was showing the best correlation with groundwater level in the study area.KeywordsGroundwaterCorrelationMann–Kendall test
