Waterside space provides a good landscape and a relaxing space in urban areas. However, some people are vulnerable to the reflected light from the water surface. Some children have a weak tolerance to scattering light, and some elderly people are vulnerable to glare from strong light. The only medical advice to the weak in response to such light could be to teach them not to approach waterside spaces. At present, there is no fundamental solution, and the situation requires assistance from engineering technology. In this study, we tried to obtain basic knowledge to control the characteristics of reflected light from the water surface by conducting hydraulic experiments. Also, we investigated the condition of waterside space using a structure with water flow in urban space. Based on the results, a method for designing waterside space was considered from the viewpoint of human visual effects.
