Biography

Grzovic received her BS in Civil and Environmental Engineering from Northern Arizona University in 2005. She continued on to Oregon State University where she earned a Masters of Ocean Engineering in 2007. Following completion of her MS, Grzovic entered the professional world. Between 2007 and 2009, she worked as an Ocean Engineer for Sea Engineering, Inc. located in Santa Cruz, California. While at Sea Engineering, Grzovic worked primarily with data, laboratory and field analysis using oceanographic equipment in aquatic coastal and estuarine environments. In 2009 Grzovic began working as a Coastal Engineer at the U.S. Army Corps of Engineers (USACE), San Francisco District in California. While at USACE Grzovic completed projects involving estuarine sedimentation, coastal flood risk and dredge material placement. In Fall 2013, Grzovic began pursuing her Ph.D. at Saint Louis University. Her dissertation focuses on sedimentation patterns along the Mississippi River under the advisement of Dr. Amanda Cox.

Research

River confluences are known for abrupt changes in flow structure, sediment transport, and morphology due to the convergence of water and sediment from the merging tributaries. This region of complexity is referred to as the confluence hydrodynamic zone (CHZ). In highly engineered systems, such as the Mississippi River (MR), complexities in the CHZ are compounded due to the presence of and interaction with river training dikes. The MR is routinely monitored and dredged to ensure navigation safety; however, the morphologic response of the CHZ to the presence and interaction of dikes remains unknown. Utilizing over 500 historic hydrographic surveys collected by the U.S. Army Corps of Engineers, Saint Louis District, Grzovic’s research focuses on quantifying the hydraulic and morphologic aspects of three small tributaries entering the MR that are known to have persistent downstream sedimentation. This work will be used to develop design standards for river training near tributary junctions.
