It was replicated as a gently curving path and serpentine water elements in English landscape designs, such as Capability Brown’s 18 th-century water features. The aesthetic appeal of the line of beauty may explain its persistence through time in landscape design. While recognizing the role of aesthetics in river restoration, especially in urban settings, designs can be expanded to include disorderly planform designs with non-symmetrical single-thread meanders and multi-threaded channels with forms inspired by local ecology, geomorphology, and social values. We also describe drawings that did not depict the ideal meander but showcased a diversity of channel forms and restored river scenes. We consider possible explanations for why respondents depicted idealized meanders. Most scientists depicted single-thread meanders for the restored channel form with some drawings including large wood in the channel, multi-thread channel forms, and wildlife and human elements. To see if freshwater scientists would draw a similar restored planform, we asked scientists to illustrate a restored channel and observed what patterns emerged from the drawings. In some restoration projects, the channel planform follows repeating symmetrical bends. The aesthetic appeal of s-shaped curves in art and landscape design may help explain the prevalence of single-thread meandering channels in river restoration projects where the channel planform is reconfigured.
