I am a first-year Master’s student in the Coastal and Computational Hydraulics Team at NC State. As an undergraduate at the University of Massachusetts – Amherst, I became interested in water resources engineering and numerical modeling. My undergraduate research experience in groundwater modeling and my appreciation of numerical modeling and fluid mechanics led to an opportunity to study coastal and computational hydraulics at NC State.

The North Carolina Flood Inundation Mapping and Alert Network (FIMAN, fiman.nc.gov/fiman) is used by NC Emergency Management for decision support regarding flooding. My current research project involves connecting ADCIRC forecast data to the geospatial dataset used by FIMAN for the purpose of providing emergency managers with more accessible and convenient visualization of coastal flooding forecasts in real-time. This involves downscaling the ADCIRC forecast data to meet the resolution of the FIMAN datasets, and examining the impact of such downscaling on forecast accuracy.

I am a PhD student in Coastal Engineering at NC State University. My research interests mainly include coastal hydrodynamics, numerical modeling, and sediment transport. During my masters at the University of Tehran, I worked on morphological modeling methods to speed up the simulation time of coastal erosion and sedimentation near a breakwater.

Currently, I’m involved in the NC Sea Grant project “Interactions between Waves, Flooding and Beach Morphology during Storm Events.” As part of my research, I am modeling the breaching of the Outer Banks during storm events. The goal is to extend the domain and provide a guidance for the entire Hatteras Island. For this purpose we are using XBeach as a morphological modeling tool and ADCIRC+SWAN to model the tides and water circulations during the hurricane. Eventually we will develop a two-way coupled ADCIRC+SWAN and XBeach models so that the wave and tidal boundary condition for the XBeach domain will be provided by ADCIRC computation and after the morphology run, new topography and bathymetry data will be sent back to ADCIRC to continue the simulation.

I am a third-year Ph.D. Student at NC State University. My research interests include Numerical Modelling of Water Systems, Ocean and Coastal Engineering, Offshore Structures and Dynamic Response of Structures.

During my masters at National Institute of Technology, Calicut, my project dealt with finding the Response of Semi-Submersibles under Multi-Directional seas. The semi-submersible was modeled as a rigid body with six degrees of freedom and the multi-component mooring lines as nonlinear springs at its fair-lead point. Modified Morison equation was employed to find the wave forces and the dynamic equilibrium equation was solved in time domain using an iterative procedure by Newmark-Beta method.

As part of my research at NC State, I am now involved in the NC Sea Grant project “Strengthening the Hurricane Wave and Surge Forecast Guidance provided to Coastal Communities in North Carolina.” In this project, we were trying to improve the accuracy of storm surge predicted for the North Carolina region. This is done by refining the mesh used for running the coupled ADCIRC-SWAN model at selected regions based on the errors in mass conservation.

I am also a part of the DHS project “Improving the Efficiency of Wave and Surge Models via Adaptive Mesh Resolution.” In this project, we are trying to implement an adaptive, multi-resolution approach to increase resolution during a simulation. We will be starting with a relatively coarse resolution mesh and as the storm approaches, we will be adding regions from a fine resolution mesh. We will be also trying to optimize the use of computational resources through dynamic load balancing in which we will be reallocating computational resources to improve parallel efficiency.

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.
