دراسة الصفات الفيزيائية و الكيميائية لمياه الأبار السطحية في منطقة الكبة-الشريخان شمال غرب مدينة الموصل

Abstract EN

The aim of this research is to identify the groundwater chemistry and some hydrogeological properties for shallow aquifer in Sherikhan –Kuba area North West of mosul city .Twenty one groundwater samples were collected and analyzed for the major constituents, and salinity, pH and temperature.

The result showed a strong correlation of sulphate with calcium and magnesium where r=0.92 , r=0.90 respectively .

Factor analysis on hydrochemical variables revealed the domination of three factors that responsible of about 86.6% of the ground water quality variance, the first factor represent the impact of geological formation on ground water quality with 60.29% of variance, second factor represent of impact of agriculture activity on ground water with 13.75 % and the third factor represent of impact of environmental factor on ground water with 11.59%.

Observation of water table fluctuation for five month , in order to record the drawdown of water table , it was found that mean drawdown range from 19 to 23 cm/month for the well No.2 and 5 respectively, for the period extended from April to end August 2009 which indicate that good ground water replenishment in summer season in spite of heavy consumption of ground water for irrigation due to continuing recharge from Tigris river.
