Abstract: The practice of enhancing existing rivers and creating entirely new waterscapes has exploded in China over the past two decades. In our study of 104 randomly selected cities across China, we identified 14 types of river projects based on grey literature reports and their appearance on sequential aerial imagery, falling into three categories: ‘engineering’, ‘waterfront spaces’ and ‘ecological’ projects. ‘Waterfront spaces’ is the most common (60.5%), followed by ‘engineering’ (28.7%) and ‘ecological’ (10.8%). Using multiple stepwise regression, we found that the types of projects undertaken were strongly influenced by factors such as climate, social-economic setting, and ‘Landscape Garden City’ designation. Designation as a ‘Landscape Garden City’ was correlated with ‘waterfront spaces’, but not ‘engineering’ and ‘ecological’ projects. We found that cities in drier climates (as measured by ‘precipitation minus evaporation’) constructed more projects and they included many projects that impounded seasonal rivers to create year-round water bodies. Based on our results, we conclude that Chinese cities are still in the process of ‘decorating’ rivers, and that the ‘Landscape Garden City’ designation promoted such ‘decorating’ projects, especially ‘linear greening’ projects and ‘public spaces along rivers’. The results also demonstrate that the new river projects in China are often at odds with the local climate.
