Evaluation of geomorphic assessment methods and geomorphic performance of river restoration designs in mountain streams in British Columbia
River restoration in the steep mountain streams of British Columbia focuses on enhancing conditions for fish habitat, including salmon spawning habitat. These restoration projects are designed using 2D hydraulic models, but their performance during large flood events is relatively unknown. This project will use a set of laboratory experiments to assess the performance of common designs under large flood events. A scaled model of a restoration design will be built, and the sediment transport and topographic change of the channel during simulated floods will be measured. The project will provide the partner organization with an assessment of the current models and methodologies used to design and monitor river restoration projects.
