| River ecologists are also river-basin planners. However, their role in planning has developed slowly over the decades since the beginning of the 20th century. Three major factors explain this phenomenon. First, ecologists focused on plant and animal communities rather than on broader policy issues related to land settlement and water development. Second, the federal government, and most state and local governments as well, used mainly economic criteria to justify projects. Intangible benefits, including the value of species or an aesthetically pleasing landscape, drew relatively little attention. Third, the public generally favored development, especially during the Great Depression of the 1930s. Only after World War II did the public's position shift in... |

| Many river restoration projects fail. Inadequate project planning underpins many of the reasons given for failure (such as setting overly ambitious goals; selecting inappropriate sites and techniques; losing stakeholder motivation; and neglecting to monitor, assess, and document projects). Another major problem is the lack of an agreed guiding image to direct the activities aimed at restoring the necessary biophysical and ecological processes within the logistic constraints of on-ground works. Despite a rich literature defining the components of restoration project planning, restoration ecology currently lacks an explicit and logical means of moving from the initial project vision through to on-ground strategies. Yet this process is fundamental because it... |

| Among the most visually striking river restoration projects are those that involve the creation of a new channel, often in a new alignment and generally with a form and dimensions that are different from those of the preproject channel. These channel reconstruction projects often have the objective of creating a stable, single-thread, meandering channel, even on rivers that were not historically meandering, on rivers whose sediment load and flow regime would not be consistent with such stable channels, or on already sinuous channels whose bends are not symmetrical. Such meandering channels are often specified by the Rosgen classification system, a popular restoration design approach. Although most projects of this type have not been subject to objective... |
