The aim of this work is to present the hydrochemical mechanisms describing the system of the Euphrates River before and after mixing with groundwater from the springs of Hijlan (western Iraq). Continuously, the data generated from these springs water have been adapted to provide an updated assessment for future water therapeutic purposes. Physicochemical characteristics of water in the mixing plume of Hijlan Creek and Euphrates indicate the multi Hydrochemical plumes as revealed by the spatial variation of important parameters related to the ecological parameters including K+, Na+, Ca2+, Mg2+, HCO3, SO42−, Cl, NO3, PO43−, Pb, Zn, Cd, Fe, Mn, Temp, DO, BOD5, H2S, Turbidity, EC, pH, and TDS. The re-aeration (k2) and de-oxygenation rate (k1) coefficients, as well as the self-purification factor (f) of the mixing plume, are 0.51, 2.03 and 0.25 s−1, respectively. The Cl concentration in the confluence zone changes, due to the chloride content mixing rates of 7.1 and 92.9% for Euphrates and Hijlan creek water, respectively, with water discharge of 316,224 m3/day and chloride load discharge of 420 tons/day. The assessment of the water quality indicates unsuitability for aquaculture purposes. However, the water can be used for therapeutic purposes and to cure multiple diseases.

Hijlan Creek 泉对幼发拉底河水质的影响和污染羽流的水化学特征

这项工作的目的是展示描述幼发拉底河系统在与来自 Hijlan(伊拉克西部)泉水的地下水混合之前和之后的水化学机制。不断地,从这些泉水中产生的数据已经被调整,为未来的水治疗目的提供更新的评估。Hijlan Creek 和 Euphrates 混合羽流中水的物理化学特征表明,与 K +、Na +、Ca 2+、Mg 2+、HCO 3 - 等生态参数相关的重要参数的空间变化揭示了多水化学羽流, SO 4 2− , Cl - , NO 3、PO 4 3−、Pb、Zn、Cd、Fe、Mn、Temp、DO、BOD 5、H 2 S、浊度、EC、pH 和 TDS。再曝气(k 2)和脱氧速率(k 1)系数以及混合羽流的自净化因子(f)分别为0.51、2.03和0.25 s -1。由于幼发拉底河和希吉兰河水的氯化物含量混合率分别为 7.1% 和 92.9%,排水量为 316,224 m 3,因此汇流带中的 Cl -浓度发生变化/天,氯化物负荷420吨/天。水质评估表明不适合水产养殖。然而,水可用于治疗目的和治愈多种疾病。
