Abstract
The roles of man-made weirs were well-known as flooding control in summer monsoon, but the function of wintering habitat for wintering water birds were not revealed. This study examined the effects of man-made weirs on the wintering distribution of water birds in Tancheon Stream, Korea, with a focus on the effects of freeze-thaw process. Data collected during January to February 2003 included thawed water surface ratios, water depths, sandbar areas, and bird distribution under different weather conditions. The analysis revealed a strong positive correlation between thawed surface areas in front of weir’s drop structures and the abundance of dabbling and diving water birds during severe cold conditions with temperatures below - 9°C. However, it was also observed that the stagnant water impounded by the weirs tended to freeze easily in winter, making it difficult for water birds to inhabit those areas. These results suggest an adaptation process against man-made weirs by wintering water birds in urban streams, provide significant insights for improving the function of weirs to enhance water birds’ habitats, especially in urban stream management.
