Water quality indexes (WQI) are a practical way to evaluate and compare the level of chemical contamination of different water bodies and to spatially and temporally compare levels of pollution. The purpose of this study was to check if these indexes are appropriate for intermittent rivers under arid and semi-arid climates. A literature review enabled the comparison of 25 water quality indexes to discern their capability to evaluate spatial (inter and intra catchment) and temporal (high and low water flow conditions) variations in water quality in three Mediterranean intermittent rivers: the River Vène (France) and the Oued Fez and the River Sebou (Morocco). Hierarchical cluster analysis identified groups of WQI with similar behavior and brought to light the 6 most distinguishing indexes. Whatever the hydrological conditions at the two sites, both the ME-MCATUHE and NCS indexes, which were developed for Morocco and Greece, and the CCMEWQI and BCWQI indexes, which were developed for non-arid or semi-arid zones, gave appropriate water quality evaluations.
水质指数 (WQI) 是评估和比较不同水体化学污染水平的一种实用方法,也是时空比较污染水平的一种方法。本研究的目的是检验这些指数是否适用于干旱和半干旱气候下的间歇性河流。通过文献回顾,比较了 25 种水质指数,以辨别它们在评估三个地中海间歇性河流(法国的 Vène 河、摩洛哥的 Oued Fez 和 Sebou 河)的空间(流域内和流域间)和时间(高水和低水流量条件)水质变化方面的能力。层次聚类分析确定了具有相似行为的 WQI 组,并揭示了 6 个最具区别性的指标。无论在这两个地点的水文条件如何,为摩洛哥和希腊开发的 ME-MCATUHE 和 NCS 指数,以及为非干旱或半干旱地区开发的 CCMEWQI 和 BCWQI 指数,都能对水质进行适当的评估。
