Advances in Geologic Data Collection and 3D Geologic Modeling for Site Characterization and Safety Studies for Dams and Levees: Instructors

Robert P. Cannon, PG
Principal/Sr. Vice President
Schnabel Engineering

Robert Cannon is a registered Professional Geologist and a Principal with Schnabel Engineering. Robert brings more than 40 years of experience nationally and internationally in geologic site characterization, geologic hazard assessments, and forensic and remedial investigations for major dams, tunnels and other critical infrastructure projects. Robert currently serves on the Board of Directors for USSD and has also served on the expert Board of Consultants for several high-profile projects, including for the Mosul Dam in Iraq which suffers from rapid and continuous foundation dissolution due to gypsum and carbonate geology.

Gary D. Rogers, PG
Senior Associate 
Schnabel Engineering

Gary Rogers is a registered Professional Geologist and a Senior Associate Scientist at Schnabel Engineering. Gary has over 30 years of technical and managerial experience in engineering geology, hydrogeology, glaciology, and site characterization. He has led site exploration and characterization programs for numerous new and existing earthen and concrete dams throughout the continental US and Alaska, and continued his involvement on many of these projects through design and construction. Much of his focus is on effectively communicating geologic and subsurface conditions to design engineers and owners.

Frederic Snider, PG
Associate
Schnabel Engineering

Frederic Snider is a registered Professional Geologist and an Associate Scientist at Schnabel Engineering. Fred brings more than 40 years of experience in geology, geophysics, hydrogeology, site safety assessments, site characterization, and fault investigations for dams and other large engineering projects. Over his career, he has worked on large and complex dam projects throughout the US and overseas. Fred currently leads the 3D Geologic Modeling team within Schnabel’s Dam Engineering Group, focusing on the application of 3D modeling to address dam safety issues, potential failure modes, and risk assessments.

Guy-Justin Nuyda, GISP
Senior Staff Scientist
Schnabel Engineering

Guy-Justin Nuyda is a certified Geographic Information Systems Professional, and leads the GIS Systems team for Schnabel Engineering’s Dam Engineering Group. Guy has a PhD in Geography Cognitive Science. He is responsible for applying GIS tools to all aspects of dam engineering, including support of Schnabel’s 3D Geologic Modeling Projects. Guy is also responsible for integrating GIS with our existing 3-D CAD system to merge geospatial and engineering drawings into a true 3-D project information system.
