The St. Louis Geo-Institute Chapter launched the event in 2011 as GeoConfluence. The name was chosen to invoke the “coming together” of knowledge, ideas, and the geocommuity in the St. Louis region.

The conference was started in conjunction with the University of Missouri Graduate Student Organization, and has been hosted by the St. Louis Geo-Institute Chapter from 2011-2015. Attendance during those years was approximately 125 to 140 professionals and students.

Since 2016, the St. Louis Geo-Institute (G-I) has partnered with the St. Louis Structural Engineering Institute (SEI)  to hold a larger joint conference, re-named Structural and Geo-Confluence. The joint conference is attended by approximately 200 professionals and students, with 20 exhibitors.
