AB: The design of stream restoration projects can be greatly aided by the availability of the latest results from basic research on river science and engineering. These results, however, need to be cast in a form that can be directly used by the practitioner. Academics have from time to time engaged in vigorous criticism of the scientific and engineering basis for the practice of stream restoration, but without necessarily offering easily accessible alternatives. The National Center for Earth-surface Dynamics is attempting to fill the gap between basic research and practice by developing the Stream Restoration Toolbox. Several of the tools under development are presented. These include: a) a predictor for bankfull geometry in gravel-bed streams, b) a designer for threshold channels, c) a predictor for the response of a river to the restoration of flood flows and d) a discriminator for braided and meandering streams. Each tool in the toolbox includes a central PowerPoint presentation, and may include Excel files to allow for direct calculation. The tools will be downloadable from the NCED web site at no cost. Each tool will be beta-tested by a group of practitioners.
