Advances in understanding the nature of debris flow behavior, and consequent improvements to landslide risk mitigation, depend to a large extent on the collection, analysis and interpretation of event data. Data that are collected in a systematic manner allow for a direct comparison of events within a region and, more generally, also enable a comparison of event characteristics between different regions. A systematic approach has been developed in British Columbia for collecting field data while traversing the path of a debris flow event, from the point of origin to the point of terminal deposition. The nature of the current methodology is described as a step-by-step procedure, with reference to the landslide profile data card developed by the BC Ministry of Forests. Its application is illustrated with field data and interpretation of those data for guidance on debris flow travel distance, with application to terrain stability assessment in forest development planning.
