近几十年来的人类活动导致南亚河流水环境日益恶化。这种退化引起了尼泊尔主要城市居民的担忧，包括加德满都谷地的居民。流域河流的恶化与卫生条件普遍较差以及向河流排放废水的工业的存在直接相关。本研究旨在利用加拿大环境部长理事会水质指数 (CCME WQI) 调查加德满都谷地主要河流水生生态系统和休闲的水质状况。使用 10 个物理化学参数来确定 20 个不同采样点的 CCME WQI。数据分析表明，农村地区水质为优到良，而人口稠密的聚居区和核心城区水质较差。研究结果预计将为政策制定者提供有关研究地区当地人使用河水的宝贵信息。
Human activities during recent decades have led to increased degradation of the river water environment in South Asia. This degradation has led to concerns for the populations of the major cities of Nepal, including those of the Kathmandu Valley. The deterioration of the rivers in the valley is directly linked to the prevalence of poor sanitary conditions, as well as the presence of industries that discharge their effluents into the river. This study aims to investigate the water quality aspect for the aquatic ecosystems and recreation of the major rivers in the Kathmandu Valley using the Canadian Council of Ministers of the Environment water quality index (CCME WQI). Ten physicochemical parameters were used to determine the CCME WQI at 20 different sampling locations. Analysis of the data indicated that the water quality in rural areas ranges from excellent to good, whereas in denser settlements and core urban areas, the water quality is poor. The study results are expected to provide policy-makers with valuable information related to the use of river water by local people in the study area.
