Rainfall causes shrinking and swelling as it infiltrates expansive soil. TRB will host a webinar on Thursday, April 29, 2021 from 1:00 to 2:30 PM Eastern to clarify this behavior and the related failure of shallow slopes. Presenters will begin with the problems from a state department of transportation perspective, move into the maintenance issues, development of the field instrumentation plan, and continue through the numerical coupled flow deformation analysis. Presenters will also discuss possible solutions.


This webinar was organized by TRB’s Standing Technical Committee on Moisture and Temperature Effects on Geomaterials.


Some registrants will need to pay $95 to attend this webinar. Sign into to view registration information.

Webinar agenda and presenters

  1. Lessons learned from analyses of slopes: Mohammad Sadik Khan, Jackson State University
  2. Possible repair method to shallow landslides made in expansive soil: Mike Stroud, Mississippi Department of Transportation
  3. Question and answer session: Moderated by Cindy Smith, Mississippi Department of Transportation


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. Discuss shallow slope failure due to moisture build up
