| The assessment of irrigation water quality is a standout amongst the most critical variables that ought to be considered in irrigation projects management, because it has a huge impact on agriculture growth and production. This study has assessed the irrigation water quality status of new Hussainiyah canal in Karbala city, Iraq. Twelve water quality parameters with regard to four observing stations during the year 2015 were surveyed. The 48 samples were tested for, Electric Conductivity, pH value, Total Dissolved Solids, Sodium, Sodium Absorption Ratio, Soluble Sodium Percentage, Sulphate,Calcium, Magnesium, Potassium, Chloride and Alkalinity(EC, PH, TDS, Na, SAR, SSP, SO4, Ca, Mg, K, Cl and Alk). These stations were scattered along the new Hussainiyah canal from upstream to downstream and named as ( Salamiyah, Abrahimiyah, QuntaraBedah and Safie). Canadian Water Quality Index (CWQI) technique was applied to make the assessment according to regular time variations(every four months for each station). The results indicated that the irrigation water quality of new hussainiyah canal was in fair conditions for stations, Salamiyah, Abrahimiyah and Quntara Bedah, while it was marginal to fair conditions for Safie station. Also, the conditions of the quality for irrigation water in the canal were not match the eligible levels for some times at the period of study. Regular monitoring for irrigation water quality status and reducing the pollution roots should be adopted from water resources authorities in province of Karbala to pre save that valuable artery source of water. | ||
