Imagine if the boundary you surveyed was constantly moving. Ambulatory water boundaries - boundaries that are subject to change due to the nature of riparian or littoral action - present some of the most difficult and time-intensive property location issues that a surveyor may encounter. In this interactive online course, you will learn about shoreline changes, the effects of inland accretion or reliction, erosion or inundation changes and the effects of avulsion (the process of sudden detachment or addition of land), navigability, and how these actions may affect property boundaries. You will also review the basic principles of boundary law that apply to riparian surveys.
