Groundwater Level Trends Over Southern India
Groundwater is essential for obtaining freshwater and plays a crucial role in promoting sustainable development in agriculture, industry, and the socioeconomic status of an area. However, due to the extensive use of groundwater, many areas in India are facing a decline in their groundwater levels. Groundwater level time series analysis aids in detecting trends, analyzing behavior, and determining the causes of water level decline. We considered four seasons for identifying the trends in groundwater levels i.e. Post-Monsoon Rabi, Monsoon, Pre-Monsoon and Post-Monsoon Kharif seasons. Using Mann–Kendall test, analysis of trends for Southern India which consists of 8 states was performed. Data on the piezometric level of 181 observation wells from 1996 to 2018 has been taken into consideration. The significant declining trend was observed in 47 observation wells in monsoon season, 61 wells in post-monsoon Rabi, 27 wells in post-monsoon Kharif and 45 wells in pre-monsoon from the results. Out of all wells only one well exhibited increasing trend over 8 states. The outcomes of the study are going to help the groundwater development authorities in the respective states for resource management, water supply planning, groundwater recharge management, environmental protection and policy formulation and regulation.
