ASCE has honored Jean-Louis Briaud, Ph.D., P.E., BC.GE, Pres.21.ASCE, with the 2025 Karl Terzaghi Award for his outstanding contributions to the fundamental understanding of soil erosion, foundation engineering design and construction, and development of pressuremeter testing.

Briaud is a pioneering figure in geotechnical engineering, with a career spanning 50 years marked by significant contributions to soil mechanics and erosion control. His innovative work in pressuremeter testing, particularly the development of the TEXAM device, revolutionized in situ soil testing by offering simpler yet effective methods for assessing soil properties. This technology has been widely adopted globally, influencing foundation design and construction practices.

In the realm of soil erosion, Briaud's invention of the Erosion Function Apparatus (EFA) stands out. The EFA has become a fundamental tool in studying and mitigating soil erosion, particularly in critical applications like bridge scour, levee overtopping, and cliff erosion. Briaud’s methodologies for calculating scour depth at bridges are incorporated into the Federal Highway Administration’s design guidelines, showcasing the practical impact of his research.

Beyond his technical contributions, he has demonstrated exceptional leadership and service to the profession, holding presidential roles in prestigious organizations such as the Geo-Institute and the International Society for Soil Mechanics and Geotechnical Engineering. His dedication to education and mentorship has shaped the careers of many geotechnical engineers who are now leaders in academia and industry. His prolific output of influential publications and his numerous international awards underscore his profound impact on geotechnical engineering. Briaud’s work exemplifies the spirit of the Karl Terzaghi Award, honoring innovative research and its application to real-world engineering challenges.

The Karl Terzaghi Award is presented for outstanding contributions to knowledge in the fields of soil mechanics, subsurface and earthwork engineering, and subsurface and earthwork construction.
