Abstract
An optimization management study based on a mathematical simulation technique for Al Hillah Kifl Region with an area of 771.8 km2 is developed. The area located between longitudes of (44˚ 15′- 44˚ 27′) and latitudes of (32˚ 15′ – 32˚ 42˚) with average wind speed, sun shine, temperature, evaporation, humidity, and rainfall are 1.73m/s, 8.79hrs, 23.61c⁰, 190.21mm, 50.23%, and 8.61mm respectively occurred in the region. A complex geologic formation of Quaternary Deposits and Upper Miocene encountered there; flood plain deposits of Euphrates River and depression fill deposits which in general, consist of fine sandy silt and siltclay layers. Sixteen existing wells are used for the hydrogeologic properties estimation of the unconfined aquifer. The maximum TDS of 136.7ppm is less than the maximum allowable limits of the Iraqi Standard and world Health Organization (WHO). It is found the maximum allowable groundwater exploitation (safe yield) of the unconfined aquifer is 250m3/day/node which produces 5m drawdown at the centers of the production wells which represents a critical depletion depth; the steady state condition is obtained after 784999days of continuous pumping, moreover it is found that the maximum water demand and available surface irrigation water of 21000 m3/day/node and 20850 m3/day/node for Cotton Crop is occurred July
