TRB Webinar: Subsurface Drainage for Slope Stabilization, Part 1 of 2
168799

TRB Webinar: Subsurface Drainage for Slope Stabilization, Part 1 of 2

TRB conducted a webinar on May 29, 2013 from 2:00 p.m.- 4:00 p.m. ET that presented the results of a recently completed pooled fund research project on subsurface drainage for slope stabilization. Contact Reggie Gillum at RGillum@nas.edu for information on accessing a link to the recorded webinar.

This first webinar of a two-part series will introduce the research project, explain the limitations of the current standard-of-practice, discuss how the research methodology can improve design results, and introduce basic concepts of groundwater hydrology. In addition, it will include watershed delineation and site mapping, geophysical and subsurface data sources and methods, quantifying groundwater recharge, and hydraulic conductivity and specific yield of aquifers.

This webinar was organized by the TRB Standing Committee on Engineering Geology (AFP10). On June 25, 2013, TRB conducted a webinar on Subsurface Drainage for Slope Stabilization, Part 2 of 2.

Webinar Presenters:
  • Tom Badger, Washington State Department of Transportation
  • Greg Pohll, Desert Research Institute
  • Rosemary Carroll, Desert Research Institute
The first 90 minutes of the webinar is for presentations and the final 30 minutes is reserved for audience questions.

Webinar Outline:
  • Research Need and current state of practice
  • Research summary
    • Previous research and its limitations
    • Research summary – new paradigm
  • Introduction to groundwater hydrology
  • Break for questions and answers (10 min or less)
  • Watershed delineation
  • Hydrogeologic mapping
  • Geophysical techniques
  • Water level data
  • Groundwater recharge
    • Precipitation
    • Soils data
    • Calculating recharge
  • Hydraulic conductivity
  • Specific yield
  • Drainage data
  • Questions and answers
Learning Objectives:
  • To learn basic background information on groundwater hydrology.
  • To recount and summarize the hydrogeologic terms and processes relevant for horizontal drainage design.
