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

Abstract

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.
