The 2026 Terzaghi Oration, Soil Erosion: From Fundamentals to Applications, summarizes 35 years of research and consulting work on soil erosion conducted by Prof. Jean-Louis Briaud with many students and colleagues around the world. It presents key findings, lessons learned, and practical applications, while also offering ideas and opportunities for the next generation of engineers and researchers.

A guiding principle throughout this work is:
Always understand the assumptions, the process, and the limitations of a software program before using it. Always use your engineering judgment to evaluate the answer.
These tools are intended to support engineering decisions, not replace engineering judgment. The responsibility for evaluating the applicability of methods, assessing uncertainties, and interpreting results remains with the engineer.
