Webinars

Recent advancements in data science and image processing, combined with higher satellite acquisition frequency and faster data delivery, have greatly improved the operational efficiency of InSAR monitoring. High-resolution InSAR programs play a key role in mitigating risks associated with tunnel construction by providing continuous, remote ground deformation insights. The extensive spatial coverage of radar satellite imagery and the availability of historical archives further support tunnel design validation and help reduce litigation risks.

This webinar will feature examples from major urban tunnelling projects currently monitored with InSAR. It will highlight the use of high-resolution Stripmap and Spotlight imagery modes, as well as advanced analytical tools for assessing and managing operational risks. In addition, the integration of AI and ML techniques for analyzing high-resolution InSAR time series and facilitating the delivery of timely geospatial insights to enhance operational efficiency will be highlighted.

Development of a representative hydrogeologic conceptual site model (CSM) is an iterative process that begins during mine exploration and permitting and continues during operations and mine closure and reclamation. Hydrogeologic data sources, field data collection methods, and analysis methods will be reviewed to efficiently characterize groundwater flow systems including effects related to mine dewatering, infiltration, and water management. Accurate characterization of geologic structures, preferential flow pathways or barriers to flow, recharge and discharge areas, and groundwater interaction with mined materials (ore, waste rock, and overburden) can streamline mine operations and may allow alternative closure and reclamation scenarios.
