An assessment of the water quality of the Oued Martil River basin (in northern Morocco) which is under natural and anthropogenic pressures was carried out over an annual cycle (spring, summer, autumn 2017 and winter 2018) at 20 sampling stations within the watershed. This assessment was conducted using biotic indices including the IBMWP (Iberian Biological Monitoring Working Party index), the QBR (Index of Riparian Quality) and the IHF (Fluvial Habitat Index). Physicochemical and bacteriological quality was also assessed based on twelve parameters (temperature, pH, electrical conductivity, dissolved oxygen, biological oxygen demand, chemical oxygen demand, suspended matter, sulphate, nitrite, nitrate, faecal coliforms, and faecal streptococci) of the surface waters of Oued Martil River basin. The scores of the biotic indices as well as the measurements of the physico-chemical and microbiological parameters classified the waters of the upstream reaches of the Oued Martil River as good quality while those of the downstream reaches were classified as poor quality.

使用理化,细菌学参数和生物指标评估摩洛哥西北部乌德·马蒂尔河流域的生态状况

在流域内的20个采样站的年度周期(春季,2017年春季,2017年秋季和2018年冬季)中,对自然和人为压力下的瓦尔德·马蒂尔河流域(摩洛哥北部)的水质进行了评估。该评估是使用生物指数进行的,包括IBMWP(伊比利亚生物监测工作组指数),QBR(河岸质量指数)和IHF(河流栖息地指数)。还根据地表水的十二个参数(温度,pH,电导率,溶解氧,生物需氧量,化学需氧量,悬浮物,硫酸盐,亚硝酸盐,硝酸盐,粪便大肠菌群和粪便链球菌)评估了理化和细菌学质量。 Oued Martil流域。
