This study explores the impact of river dredging on water quality in Suzhou, China, using a SARIMA model to predict water quality variables in rivers without dredging for comparison. The study spans the water quality data from 2019 to 2023, calculating CCME-WQI scores for each river. Results indicate that rivers Shi and Zhu, two river being dredged, showed significant increases in observed water quality index scores, while the scores for predicted water quality data for these two rivers without dredging decreased substantially. The magnitude of improvement in water quality for nearby undredged Zhao was less than one-fifth of the improvements observed in Shi and Zhu. These findings suggest that river dredging indeed leads to improved water quality within at least an eight-month timeframe. The study emphasizes the importance of employing proper dredging practices and thorough monitoring protocols to mitigate potential environmental impacts.
