Ph.D. Student (Graduate Research Assistant)
Hello! I am Rosemary Cyriac, a coastal engineering graduate student at North Carolina State University (NCSU). Over the past four years, I have worked with Dr. Casey Dietrich on improving the visualization of storm surge forecast products and modeling the hydrodynamics of estuarine systems. I find coastal modeling fascinating and have enjoyed using numerical modeling tools to understand coastal processes and being involved in delivering scientific products that aid decision makers in coastal communities. I look forward to learning more about the impacts of extreme events such as hurricanes, tropical storms, tsunamis etc along the coast, impacts of sea-level rise, mixing of riverine freshwater within estuarine systems and its interactions within the continental shelf, sediment transport and beach morphodynamics.
During my first 2 years I was a part of the NC Sea Grant project “Strengthening the Hurricane Wave and Surge Forecast Guidance provided to Coastal Communities in North Carolina”. For this project, I developed a Python tool named Kalpana that converts hurricane forecast products that are in the form of ASCII based text files into more popular formats such as ArcGIS based shapefiles and Google Earth compatible KMZ files. These file formats enhances the utility of hurricane forecast products allowing end users such as emergency managers of coastal communities to overlay forecast results with other types of geo-spatial data. Kalpana was tested during a hindcast analysis for Hurricane Arthur, a Category 2 storm that made multiple landfalls along the North Carolina coast in early July 2014. I validated forecast results (for water levels, waves heights and wave periods) issued in real-time during Arthur by the ADCIRC Surge Guidance System (ASGS) with available observations and hindcast results. Currently, I am investigating the sensitivity of these model results to uncertainties in the track and intensity predictions during the event.
Another important focus of my research, being a part of “The Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE)”, is to examine coastal ocean processes that can influence nearshore oil transport. Currently, I am working with Dr. Dietrich to develop an ADCIRC 2DDI/3D model to examine the mixing of fresh and saline waters within the Choctawhatchee Bay and River system situated along the Florida Panhandle. A series of near-shore experiments collectively known as the Surfzone Coastal Ocean Pathways Experiments were performed by CARTHE in December 2013 in this region. Satellite imagery acquired during SCOPE indicated the presence of a surface freshwater plume at the Destin Inlet that connects Choctawhatchee Bay to Gulf of Mexico. Our objective is to investigate the spatial extent and vertical profile of this river plume using the capabilities of ADCIRC 3D to simulate baroclinic flows.
Apart from research, I spend my time hanging out with my husband, cooking and catching up on current affairs and friends. I also enjoy reading books and being involved in activities at church.
