    ‎ Evaluation of spatial qualitative changes in surface water using cluster ‎analysis and factor analysis (Case study: the Aras river within the ‎boundaries of Iran)‎ by Mohammad Mostafa Shabarang‏, Ebrahim Fataei, Ali Akbar Imani, Hooman Bahmanpour, Mohammed ‏ Shabani‏

    Published 2024-11-01
    “…Therefore, based on the obtained results, it was revealed that the reason for qualitative changes at different stations is due to the entry of human pollutants from various urban, industrial, mining, and agricultural sources as well as erosion in the river basin. Therefore, given the high precision of the analytical methods used in the evaluation of the qualitative aspects of the studied river’s water, it can be acknowledged that multivariable methods such as cluster analysis and factor analysis, can confidently determine the water quality of rivers and significant parameters affecting their quality and identify pollutants in the management of river water quality.…”
