Assessment of Pre-Monsoon and Monsoon Groundwater Level and Fluctuation at Regional Level in South of Haryana; Reference to Rewari District
A present study was carried out at Dept. of Agro- Meteorology, CCS HAU Hisar to find the status of ground water in Rewari district for two decades i.e. from 1996-2017 With the main objective to investigate the temporal trends in annual and seasonal groundwater level and fluctuation in Rewari district. The study involved analysis of the ground water data for 20 years and mapped the changed in ground water levels between pre monsoon and monsoon seasons. The major activities in ground water fluctuation in five block of Rewari district involved the of existing data, generation of GIS database (shape files), interpolation, categorization, mapping and interpretation. Trend analysis has been done spatial analysis by Geographical Information Systems (GIS). The results indicated that a mix of negative and positive trends in the groundwater level series. Results also indicated the pre-monsoon ground water level influenced higher recharge of ground water than the total annual amount of rainfall. In pre- Monsoon rise in water level was found in north parts and decline was in south eastern parts. Study show that in Monsoon Central parts of Rewari district observed rising water table and South Eastern and North Western parts of district had declining water level from normal. The pre-monsoon season the groundwater level varied from 7.26 to 22.23 meters below ground level in depth and during the monsoon season the groundwater level was found to be from 10.46 meters to 22.23 meters bgl during year (2017).
