تقييم نوعية المياه الجوفية لزراعة بعض المحاصيل في محافظة النجف الأشرف باستعمال موديل (ewatsuit model)‎

Abstract EN

This study was included some chemical tests on samples of groundwater (wells) in the certain locations of Al-najaf Al ashraf, like (acidity, electrical conductivity, total dissolved solids, total hardness, chlorides, magnesium ion, sodium ion and calcium ion). The results of these tests were admitted in mathematical model named (Watsuit Model) to predict the soil bearing to the salinity and toxicity problems resulting from irrigation water insteady-state conditions.

In this away salinity or concentration of contaminated was calculated by multiplying the conductivity of irrigation water (Ec) or salt concentration with A concentration factor (Cf) with corresponds to the washing factor and depth in the root zone. Finally, the suitability of water irrigation was evaluated by comparison with.
