Continuing Education Credit Information
This seminar is open to the public. It offers 6.5 PDHs to professional engineers and 6.5 HSW continuing education hours to landscape architects in most states, including South Carolina. Educators and courses are not subject to preapproval in South Carolina.
This event has been approved by the Landscape Architecture Continuing Education System for 6.5 HSW PDHs. Only full attendance can be reported to the LA/CES.
Engineers and landscape architects seeking continuing education credit in other states will be able to apply the hours earned at this seminar, in most cases. Refer to specific state rules to determine eligibility.
The Association of State Floodplain Managers has approved this event for 6.5 CECs.
The South Carolina Board of Registration for Geologists has approved this course for 7.0 hours of personal development.
Attendance will be monitored, and attendance certificates will be available after the seminar for most individuals who complete the entire event. Attendance certificates not available at the seminar will be mailed to participants within fifteen business days.
Speakers
Dr. Gregory H. Nail, PhD, PE
Associate Professor in the Engineering Department at the University of Tennessee at MartinDr. Gregory H. Nail is a professor in the Engineering Department at the University of Tennessee at Martin where he teaches a variety of courses including fluid mechanics, hydraulics and hydrology, and hydraulic and hydrologic modeling. He holds a professional engineer’s license based on having passed both the Civil and Mechanical discipline-specific exams. Prior to coming to UT-Martin in 2002, he worked as a research hydraulic engineer for the United States Army Corp of Engineers for 11 years. He continues to be professionally active by working summer internships, carrying on consulting work, supervising senior design projects, and regularly delivering continuation programs, all oriented around computational hydraulic and computational hydrologic modeling. Dr. Nail earned his B.M.E. degree from Auburn University and his M.S. and Ph.D. degrees from Texas A&M University.
