伊斯坦布尔是世界上人口稠密的大都市地区之一，自过去十年以来一直面临缺水问题。从梅伦流域调水被认为是向伊斯坦布尔供水的最可行的选择，因为它的水势很高，水质退化相对较少。本研究由两部分组成。第一部分根据《生活饮用水地表水水质要求》的要求，对5个监测站的26项水质数据进行了分析和评价。第二部分，建立了具有简单水质动力学的一维河流水质模型。这为流域更先进的水质模型奠定了基础。评估水质数据和开发模型的原因是为就防止现有水质进一步恶化的初步行动作出决策提供信息。从取水点水质评价来看，梅仁河的NH_4+、BOD_5、粪链球菌、锰和苯酚等指标较差，COD、PO43−、总大肠菌群、总悬浮物、汞和总铬等参数不适合饮用水提取。模型计算结果与水质评价结果基本一致。研究还表明，河流沿线相对较高的无机氮和磷浓度与扩散的营养负荷有关，应与市政和工业废水一起管理。
Istanbul, being one of the highly populated metropolitan areas of the world, has been facing water scarcity since the past decade. Water transfer from Melen Watershed was considered as the most feasible option to supply water to Istanbul due to its high water potential and relatively less degraded water quality. This study consists of two parts. In the first part, water quality data covering 26 parameters from 5 monitoring stations were analyzed and assessed due to the requirements of the “Quality Required of Surface Water Intended for the Abstraction of Drinking Water” regulation. In the second part, a one-dimensional stream water quality model with simple water quality kinetics was developed. It formed a basic design for more advanced water quality models for the watershed. The reason for assessing the water quality data and developing a model was to provide information for decision making on preliminary actions to prevent any further deterioration of existing water quality. According to the water quality assessment at the water abstraction point, Melen River has relatively poor water quality with regard to NH4+, BOD5, faecal streptococcus, manganese and phenol parameters, and is unsuitable for drinking water abstraction in terms of COD, PO43−, total coliform, total suspended solids, mercury and total chromium parameters. The results derived from the model were found to be consistent with the water quality assessment. It also showed that relatively high inorganic nitrogen and phosphorus concentrations along the streams are related to diffuse nutrient loads that should be managed together with municipal and industrial wastewaters.
