Science communication and the law: Lessons learned from being an expert witness

In this paper, I focus on my personal experiences as an academic, educator, and researcher serving as an expert witness in environmental litigation. I discuss the relevance of my work in these roles within the context of two legal cases: the first, centered on soil erosion and sedimentation in small reservoirs, and the second, involving property damage from catastrophic flooding during two tropical storms.   My objective is to demonstrate the extent and impact of the geosciences overall, and the field of geomorphology specifically, in contributing to legal proceedings related to environmental disputes. Throughout the years, I have collaborated with exceptional lawyers, each of whom has been invaluable in preparing me for cases, particularly in simplifying complex concepts and conveying them effectively. The ability to articulate the scientific process and principles to non-specialist audiences, such as lawyers, judges, and juries, in a lucid and comprehensible manner, is crucial to ensuring that the expert's testimony is relatable and compelling.
