Meet the Next Generation of Dam Professionals!

Nahyan Rana, 2022 CDA Scholarship recipient, will present a webinar on the Analysis of Sentinel-1 InSAR Data to Monitor Tailings Dams and Predict Instability.

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 resultsThis 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.

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.
