Introduction to Numerical Modeling in Geotechnical Engineering with Emphasis on FLAC Modeling

January 25-26, 2019  •  Los Angeles, CA  •  Instructor: Dr. Siavash Zamiran, P.E.

MEA, Inc. of St. Louis, MO is hosting a 2-day workshop on Numerical Modeling in Geotechnical Engineering. The workshop will be on January 25-26, 2019 from 10:00 am to 4:00 pm and will be taught by Dr. Siavash Zamiran, P.E.

This course is an introduction to modeling geotechnical problems using commercially available geotechnical programs with an emphasis on FLAC. Different geotechnical programs and numerical methods will be discussed and compared with each other. Principals of numerical modeling will be described. The modeling procedure for several practical geotechnical examples (including seismic loading) will be demonstrated using FLAC. The material is useful for students and professionals in different fields including civil, geotechnical, mining, petroleum, and geology engineering. Attendees will be awarded 5 PDH Credits for a single day registration, or a total of 10 PDH Credits for full enrollment.

Topics covered in the workshop include:

  • Introduction to Computational Geotechnics
  • Commercial Geotechnical Programs
  • Theoretical Considerations
  • Numerical Modeling in FLAC


Brunswig Square Building,  360 E 2nd St, Los Angeles, CA 90012.


Day 1: January 25, 2019 10:00 am to 4:00 pm
Day 2: January 26, 2019 10:00 am to 4:00 pm


    • Fees and PDH Credits:
      • Day 1 Registration: $800 (5 PDH Credits)
      • Day 2 Registration: $800 (5 PDH Credits)
      • Both days registration: $1500 (10 PDH Credits)
    • Payment methods: Check or EFT to Marino Engineering Associates, Inc. (Payment information will be sent to all attendees after the registration form is complete.)

Dr. Siavash Zamiran, P.E., Project Engineer, Marino Engineering Associates, Inc.Dr. Zamiran received his Ph.D. in Geotechnical Engineering in 2017 from Southern Illinois University Carbondale, where he was awarded Outstanding Graduate Student. His dissertation topic was related to seismic earth pressure and motion response of cantilever retaining walls using fully dynamic analysis. He is an Adjunct Professor of Civil Engineering at Southern Illinois University Edwardsville and St. Louis University.

Dr. Zamiran is a member of ASCE, and has served on the Geo-Institute Rock Mechanics, Deep Foundations, and Geophysical Engineering Committees. Dr. Zamiran has authored more than 30 publications and is a reviewer of more than five engineering journals. Due to his commitment and substantial contributions to the engineering profession and the ASCE St. Louis Section, Dr. Zamiran was awarded the 2018 ASCE St. Louis Young Engineer of the Year Award.

Dr. Zamiran has taught many workshops on numerical modeling and geotechnical engineering, in addition to developing an original earthquake design program for retaining walls.
