Findings from a National Survey of Canadian perspectives on predicting river channel migration and river bank erosion
River bank erosion and river channel migration are geomorphic processes that can result in significant hazards when there are impacts to humans or infrastructure. Unlike flooding, there are limited national guidelines in Canada that provide recommendations on how to best assess riverine erosion hazards. Instead regional and local jurisdictions rely on techniques based on varying levels of policy maturity. The current study presents findings of a nationwide survey on Canadian perspectives on predicting river channel migration and river bank erosion which received more than 40 responses from across Canada. Results showed that predictions were used for a variety of purposes, but that confidence intervals were rarely reported. Aerial imagery and survey‐based methods were the well‐known and widely‐used techniques for predicting river channel migration and river bank erosion. A majority of respondents identified both technical and financial challenges to improving accuracy including client willingness to pay, data quality/cost issues, and hydrologic changes due to land use and climate change. Several recommendations for improving best‐practices are provided, with a focus on the development of erosion datasets, improving data access, and providing additional training opportunities.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
