ABSTRACT
Groundwater (GW) sustainability is a key concern for the high dependency on groundwater for agricultural and domestic uses in the southwestern region of Bangladesh. So, this study intends to analyze the pattern of current and predicted changes in the water table for future development. It is based on selected wells in the Jashore district’s eight Upazilas. MAKESENS has been used to analyze the dynamics of GW levels for long-term prediction, and Geographic Information System (GIS) is utilized to visualize the results. This study reveals the annual water table (WT) depth lowering with a decreasing rate of maximum and minimum 0.17 and 0.04 m/year, respectively. The suction limit is considered 8m because shallow tube wells utilize atmospheric pressure to lift water. The standard atmospheric pressure is 1.034 kg/cm2, equivalent to 10.34m (maximum theoretical lift) of the water column, which reduces to 8m due to frictional head losses in the pipe. It is anticipated that the WT of some of the study area’s locations will be lowered beyond the suction limit by 2030 if the declining trend continues. This research’s findings may be useful in understanding the GW situation, GW management, and GW related activities in the study area.
