This study aims to model pollution dynamics and quantify pollutant loads to improve river water quality management.
Field measurements and secondary data collection were conducted.
The QUAL2Kw model was employed to simulate spatial variations of key water quality parameters.
Pollution loads from point and non-point sources were estimated and analyzed.
Significant spatial variability in water quality was observed, with increasing pollutant concentrations downstream.
Several river segments exceeded permissible water quality standards for biochemical oxygen demand and chemical oxygen demand.
Scenario analysis suggested that reducing domestic wastewater inputs could greatly improve water quality.
