Description

Sediments within the portion of Victoria Harbour are managed by Transport Canada. These sediments have been the subject of numerous environmental investigations that have documented the presence of certain contaminants in Harbour sediment. The site location within the Harbour extends generally from the Selkirk Trestle north of the Upper Harbour to the Outer Harbour breakwater south of Ogden Point. As part of risk assessment activities for the site, a study was conducted to determine potential impacts to the benthic community and long-term sediment recovery within the site due to vessel-induced sediment disturbance and erosion. The results of these evaluations were used to develop maps correlating vessel operations, erosion potential of bed sediments, and vertical scour depths throughout the site. This information was used to assist in interpretation of benthic community assessment data and develop a better understanding of the influences on the benthic community in Victoria Harbour. This presentation will provide a discussion of the how the evaluation was conducted, present the results, and provide an overview of the implications of study based on study objectives.
