My research interests span coastal, estuarine, and riverine settings, with a broad focus on the interplay of hydrodynamics (currents, waves, turbulence), morphodynamics (sediment transport), and coastal ecosystems (mangroves, coral reefs).
Dr. Benjamin Norris is a Mendenhall Postdoctoral Scholar and Research Oceanographer with the USGS Pacific Coastal and Marine Science Center. His expertise spans coastal, estuarine, and riverine settings, with a focus on nearshore processes, wave dissipation, turbulence, sediment transport, and the hydrodynamics of aquatic vegetation. His research interests include the development of “green infrastructure”, or nature-based solutions for mitigating coastal hazards and erosion. His Mendenhall project focuses on modeling wave dissipation across coral reefs at sub-meter scales, with the purpose of developing cost-effective coral reef restorations to enhance the protective capacity of degraded reef ecosystems. Benjamin is skilled in field observation, remote sensing (GIS), computer programming (Matlab, Bash/Linux, C++), and numerical modeling (OpenFOAM, Delft3D).
