Spatial Analysis of Groundwater Fluctuation in Nathusari Chopta Block of Sirsa District (Haryana, India) using Geospatial Technology

摘要

The present research demonstrates the spatial-temporal changing in the groundwater leveLof the study area i.e., Nathusari Chopta block of Sirsa district. The 15 locations of dug-wells were taken to observe the ground water level of pre-monsoon and monsoon season for two decades (1996-2018). The fluctuations in the groundwater level during two decades in the area were also analysed. The interpolation technique of geospatial technology was used to analyse and mapping of the ground water level and its fluctuation. The groundwater level of two decades showed a range from 1.28 meter below ground level to 29.4 m (bgl) over the locations. The ground water fluctuation of the area had upwelling trained as result showed that upto 6 meter water table rose during the period. The study showed uprising trend in average groundwater level from 12.37 m bgl in 1996 to 7.56 m bgl in year 2018. The changes in the groundwater level were more prominent in centre, North-east and West as rising trends in the area. The probable reason for this trend may be the poor groundwater quality in western and northeastern parts of the area hampering the farmers from its use. The central part of area is most affected by water table rising problem and most of the area suffers from Waterlogging and soil salinity. The major aim of the study was to find out the spatial and temporal changes in the seasonal groundwater level and its fluctuations.
