Management of groundwater resources in the Al-Mansourieh zone in the Diyala River Basin in Eastern Iraq

Three scenarios of operation times (12, 8 and 6) hours/day were taken to test the drawdown head of groundwater resources in the Al-Mansourieh zone in the Diyala River Basin in Eastern Iraq. In operation time with 6 h/day, the drawdown head of groundwater in five cells begins with less than 1 m for cell (i = 40, j = 38) and increase to reached maximum value about 15 m for cell (i = 75, j = 45) in 20th year and the dry cell not appear until 8000 day. These results indicate that the 6 h/day is the optimum operation time to keep the wells without drying.299
