The Yamuna river has become one of the most polluted rivers in India as well as in the world because of the high-density population growth and speedy industrialization. The Yamuna river is severely polluted and needs urgent revival. The Yamuna river in Dehradun is polluted due to exceptional tourist activity, poor sewage facilities, and insufficient wastewater management amenities. The measurement of the quality can be done by water quality assessment. In this study, the water quality index has been calculated for the Yamuna river at Dehradun using monthly measurements of 12 physicochemical parameters. Trend forecasting for river water pollution has been performed using different parameters for the years 2020–2024 at Dehradun. The study shows that the values of four parameters namely, Temperature, Total Coliform, TDS, and Hardness are increasing yearly, whereas the values of pH and DO are not rising heavily. The considered physicochemical parameters for the study are TDS, Chlorides, Alkalinity, DO, Temperature, COD, BOD, pH, Magnesium, Hardness, Total Coliform, and Calcium. As per the results and trend analysis, the value of total coliform, temperature, and hardness are rising year by year, which is a matter of concern. The values of the considered physicochemical parameters have been monitored using various monitoring stations installed by the Central Pollution Control Board (CPCB), India.

使用不同理化参数分析水污染：亚穆纳河研究

由于高密度的人口增长和快速的工业化，亚穆纳河已成为印度乃至世界污染最严重的河流之一。亚穆纳河受到严重污染，急需恢复。德拉敦的亚穆纳河因异常的旅游活动、糟糕的污水处理设施和污水管理设施不足而受到污染。水质的测量可以通过水质评估来完成。在这项研究中，使用每月测量的 12 个物理化学参数计算了德拉敦亚穆纳河的水质指数。在德拉敦使用不同的参数对 2020-2024 年的河流水污染进行了趋势预测。研究表明，四个参数的值，即温度、总大肠菌群、TDS、和硬度逐年增加，而 pH 值和 DO 值没有大幅上升。该研究考虑的物理化学参数是 TDS、氯化物、碱度、DO、温度、COD、BOD、pH、镁、硬度、总大肠菌群和钙。根据结果​​和趋势分析，总大肠菌群、温度和硬度的值逐年上升，这是一个值得关注的问题。已使用印度中央污染控制委员会 (CPCB) 安装的各种监测站对所考虑的物理化学参数的值进行监测。大肠菌总数、温度、硬度值逐年上升，值得关注。已使用印度中央污染控制委员会 (CPCB) 安装的各种监测站对所考虑的物理化学参数的值进行监测。大肠菌总数、温度、硬度值逐年上升，值得关注。已使用印度中央污染控制委员会 (CPCB) 安装的各种监测站对所考虑的物理化学参数的值进行监测。
