Many stream restoration projects are designed with the Natural Channel Design approach, which involves construction of single-thread meandering channels based on formulas for channel form. In some projects, the channel planform follows repeating symmetrical bends. To see if freshwater scientists would draw a similar restored planform, scientists were asked to illustrate a restored channel and observed what patterns emerged from the drawings. 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. This study considered possible explanations for why respondents depicted idealized meanders.
