New tools and process workflows incorporating geophysical site investigation are available to make data-driven evaluations of bridge scour and erosion for risk assessment and resilient design. TRB will host a webinar on Thursday, October 26, 2023 from 1:00 PM to 2:30 PM Eastern that will describe the use of geophysical techniques for subsurface exploration and subsequent data analysis along with application for subaquatic characterization of historical and existing scour conditions. These techniques create holistic earth models for geotechnical analysis and risk and resilience assessment. Presenters will also discuss process workflow and the advantages associated with design, analysis, and visualization of geophysical data for decision-making.

This webinar is sponsored by TRB’s Standing Technical Committees on Geotechnical Instrumentation and Modeling, Hydrology, Hydraulics, and Stormwater, and Mechanics and Drainage of Saturated and Unsaturated Geomaterials.

Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $100. Sign into to view registration information. Contact Patrice Davenport to inquire about becoming a TRB sponsor or global affiliate organization.

A recording will be sent to all registrants after the webinar.


Webinar agenda and presenters

  1. Application of low- to high-frequency acoustic methods for seabed characterization regarding scour and erosion risk assessment – Nina Stark, Virginia Tech

  2. Integrated geophysical and geological investigations to characterize sedimentological and anthropogenic conditions in support of design, monitoring, and rehabilitation of bridges – Matt Art, e4sciences

  3. A cloud connected field-to-design workflow for transportation infrastructure ground engineering – Laura Quigley, Seequent

  4. Question and answer session moderated by Derrick Dasenbrock, Federal Highway Administration

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions.


Learning Objectives

At the end of this webinar, participants will be able to:

  1. Understand acoustic methods for shallow and surficial seabed soil characterization in scour and erosion risk assessment application

  2. Identify the benefits of integrated geophysical characterization

  3. Describe the advantages of an integrated geotechnical, geological, and geophysical data approach for a holistic understanding of subsurface conditions


Professional Development Hours

Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded 1.5 Professional Development Hours (PDHs). TRB’s webinar program awards PDH credits only to the registered individual, and not to other members of a group that view the webinar together. To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.

This webinar will be delivered as a scheduled – e-learning live event and is categorized within RCEP as Technical, Health and Safety.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

TRB will report credits earned to the Registered Continuing Education Program (RCEP). Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, D.C., 20005.
