This study explored countermeasures of environmental remediation in small-scale urban rivers via a case study on a river within the campus of a university. The water quality of the campus river was investigated, and the water environment capacities were then estimated. Subsequently, the effectiveness of previous remediation projects in improving the river water quality was assessed, after which some suggestions were presented for a more effective remediation in the future. The study identified one sector(i.e., Z4) with the highest chlorophyll a concentration, indicating a high risk of algal bloom in this sector. Moreover, there were 19% and 88% of the sampling stations, respectively, of which the TN and TP concentrations exceeded the standard level IV. The water environment capacities for TN and TP were 12.38 kg/d and 1.05 kg/d, respectively. Based on these findings, it is suggested to promote environmental remediation measures including restoration of aquatic vegetation and construction of ecological embankment and treatment wetland as well as water diversion project in the campus river, with a special emphasis on the sectors H2 and Z4. Meanwhile, it is also recommended to promote sponge campus construction and campus environmental education projects to achieve more promising performance of the river restoration projects.
