In October 2022 Nahyan Rana, as a PhD Candidate in Engineering Geology at the University of Waterloo, received the CDA Gary Salmon Memorial Scholarship for his research work. It’s now time for Nahyan to present his student research work.
Recent occurrences of tailings dam failures have prompted public calls for more robust monitoring programs. Satellite InSAR technology has grown in popularity due to its powerful ability to detect millimetre-scale displacements in infrastructure. However, the literature on InSAR applications on tailings dams is relatively limited compared to other engineering sectors.
Nahyan's analysis of Sentinel-1 InSAR data to monitor performance of tailings dams will provide key insights into how factors such as environmental conditions, software selection, satellite-dam orientation and geometry, tailings dam size, and case-specific knowledge influence the quality and interpretation of Sentinel-1 InSAR results. This research delivers practical considerations that are of value to geotechnical engineers and remote sensing geoscientists in the tailings management industry.
In this presentation, Nahyan and his supervisor Professor Steve Evans will share findings from ongoing research that aims to address the following questions by using open-source Sentinel-1 InSAR data:
This webinar is intended for Geotechnical engineers, remote sensing geoscientists and university students pursuing or with an interest in InSAR technologies and/or in performance monitoring of dams.

This webinar will be presented by Nahyan Rana and his supervisor Professor Steve Evans from the University of Waterloo.
Dr. Nahyan Rana is a Geoscientist-in-Training at Klohn Crippen Berger and recently completed his PhD at University of Waterloo, specializing in Engineering Geology and Remote Sensing for Tailings Dams. As part of the CanBreach project, his research involved studying historical failure rates, using satellite images to map inundation areas, and using satellite InSAR technology to map deformations in tailings dams. His work has contributed to improved case history knowledge in dam breach studies and hazard-risk assessments. Nahyan is also active in the ICOLD Tailings Committee.
Professor Evans has four decades of research experience on natural hazards, with a focus on catastrophic landslides, landslide dams, glacial hazards, and tsunamis. His expertise is on engineering geology, geospatial modelling, hazard and risk assessment, and urban damage systems. He is one of the lead professors in the CanBreach project that focuses on tailings dam failures and was the supervisor of Nahyan Rana during his doctoral program.
