This study evaluated the management priority of small catchments in the Nam River basin, comprehensively considering the impact of non-point pollution sources for water quality improvement. Water quality data from the Water Environment Measurement Network and additional field survey data were collected to understand the water quality status at the small catchment level. The management priority was calculated by integrating data on pollution sources, land cover, and runoff using a weighted method. As a result, the E08-2 small catchment, located downstream of the Nam River, showed the highest priority, followed by A18, B09, E04, and A19. The main factor influencing the water quality improvement priority was the pollution source characteristics within the small catchment, especially the influence factor and land use condition. This study contributes to the efficient water quality management of the Nam River basin by identifying the priority by small catchment through analysis that simultaneously considers point and non-point pollution sources.
