Vicki Nguyen, Geotechnical Engineer, Klohn Crippen Berger, presents her talk "Calibration Model for the Coteau Embankment at Gardiner Dam".

Abstract: With support from the Saskatchewan Water Security Agency, KCB has been assessing the potential deformation mechanisms associated with the historical displacements measured within the foundation below Gardiner Dam. To investigate the observed response, KCB has developed a 3D deformation model using FLAC3D to simulate the ground conditions and dam geometry to simulate the dam construction in stages. By comparing the model displacements to the measured data, the material parameters can be calibrated and then the model can be used to predict the future response of the foundation below the embankment structures. This presentation summarizes the basis, methodology, and results of the calibration model for the Coteau Embankment at Gardiner Dam.

Speaker Bio: Vicki Nguyen has twelve years of experience working as a geotechnical engineer (P.Eng.) in Alberta and British Columbia, after graduating from the University of Waterloo with a BASc in Civil Engineering. Over the last eight years, she has developed numerical models in FLAC 2D and 3D to assess and design slope stabilization measures, perform seismic deformation models, and calibrate model parameters based on field and instrumentation data for tailings facilities, dam structures, and slope stabilization projects.
