Application of Numerical Model for Ground-water Management of Piedmont Aquifer in Central Dinajpur, Bangladesh

Hossain, Syed Abul
In the present study, an attempt has been made to evaluate the geologic and hydrogeologic properties of the Piedmont aquifer in the Dinajpur district and to use those evaluated values in a ground-water management model. The primary objective is to determine the maximum annual yield and corresponding annual pumping allocation for the basin based on allowable limiting drawdown up to 22 feet from the surface. The .computer model is used to determine the maximum annual yield based on predicted changes in the potentiometric surface (water table) caused by irrigation pumpage prior to 1977 and subsequent allocated irrigation pumpage until 1997.
