Water table dynamics of Dhaka city and its long-term trend analysis using the 'MAKESENS' model

摘要

The water table (WT) data of Dhaka city for 17 years (1988-2004) was analysed for assessing WT fluctuation and predicting its trend using a computer model, "MAKESENS". The analysis revealed that the WT declined drastically at different locations of the city. Moreover, the model also predicted that WT would further decline 9-25 m by the year 2015 and 18-40 m by the year 2025, rendering most wells inoperative, if the pumping rate was not reduced.
