Beyond functionality: topographical complexity as a driver of aesthetic value in urban green infrastructure

Cities face growing challenges from stormwater: flooding, pollution, and habitat loss. Green infrastructure offers solutions, yet the aesthetic dimension is often overlooked. This study introduces the Buras Beauty Scale for objectively assessing the beauty of wetland configurations and emphasises its integration into green infrastructure projects. Our methodology involved surveying diverse groups, including non-architecture students and non-traditional architects, who perceived higher beauty in wetland configurations compared to traditional architects and architecture students (mean beauty scores: 7.8 and 7.5 vs. 6.2 and 6.4, respectively). Statistical analysis revealed a strong correlation (r = 0.731, p < 0.05) between beauty assessments and Shannon-Weaver entropy, highlighting the importance of topographic diversity. We also observed that higher beauty scores correlated with greater consensus among respondents, as evidenced by a decrease in the coefficient of variation from 0.52 to 0.34. Multicriteria analyses, integrating beauty with functionality, identified optimal wetland configurations for urban landscapes.
