USSD 2026 Annual Conference
About the USSD 2026 Annual Conference
Flow Science will be exhibiting at the USSD 2026 Annual Conference and Exhibition, bringing together more than 900 dam and levee professionals for multiple days of knowledge exchange, networking, and technical sessions in Austin, TX, May 4–7, 2026. The conference features more than 130 technical sessions, a plenary session, a Legacy lecture, and a variety of workshops.
FLOW-3D HYDRO is a comprehensive CFD simulation platform built for water engineers and researchers working on dam and levee design, hydraulic structures, spillway analysis, and other complex water infrastructure challenges. Its physics-based modeling capabilities help teams evaluate hydraulic performance, reduce risk, and support more informed design decisions across a wide range of civil and environmental applications.
At the USSD 2026 Annual Conference, our team will be available to discuss how FLOW-3D HYDRO fits into your current workflow and where simulation can have the greatest impact on your projects. Stop by Booth 124 to talk with Brian Fox and Dan Gessler about your specific application.
Meet Our Booth Staff
Brian Fox, PE, is a Senior CFD Engineer at Flow Science, where he has led technical applications for FLOW-3D HYDRO since joining in 2015. He has over 20 years of experience across private, public, and academic sectors.
Brian regularly contributes to industry conferences on the role of computational modeling in water resources and environmental applications. His work spans fish passage, river restoration, bridge scour analysis, sediment transport modeling, and hydraulic structure analysis using 1D, 2D, and 3D hydraulic models.
Dan Gessler, P.E., PhD, D.WRE, is Global Water Infrastructure Lead at Flow Science, where he works to grow the adoption of FLOW-3D HYDRO through educational content, training programs, and engagement with water infrastructure stakeholders worldwide.
Prior to joining Flow Science in 2024, Dan spent over 22 years at Alden/Verdantas, where he served as National Practice Lead for Hydrology, Hydraulics, and Fluid Mechanics. Earlier in his career, he conducted research in multidimensional numeric modeling, erosion and sedimentation, and physical model studies across industry and academic settings.
