    • U.S. IOOS coastal and ocean modeling testbed : inter-model evaluation of tides, waves, and hurricane surge in the Gulf of Mexico 

      Kerr, Patrick C.; Donahue, Aaron S.; Westerink, Joannes J.; Luettich, Richard A.; Zheng, L. Y.; Weisberg, Robert H.; Huang, Y.; Wang, H. V.; Teng, Y.; Forrest, D. R.; Roland, A.; Haase, A. T.; Kramer, A. W.; Taylor, A. A.; Rhome, J. R.; Feyen, J. C.; Signell, Richard P.; Hanson, J. L.; Hope, M. E.; Estes, R. M.; Dominguez, R. A.; Dunbar, R. P.; Semeraro, L. N.; Westerink, H. J.; Kennedy, A. B.; Smith, J. M.; Powell, M. D.; Cardone, V. J.; Cox, A. T. (John Wiley & Sons, 2013-10-08)
      A Gulf of Mexico performance evaluation and comparison of coastal circulation and wave models was executed through harmonic analyses of tidal simulations, hindcasts of Hurricane Ike (2008) and Rita (2005), and a benchmarking ...
    • Underwater microscope for measuring spatial and temporal changes in bed-sediment grain size 

      Rubin, David M.; Chezar, Henry; Harney, Jodi N.; Topping, David J.; Melis, Theodore S.; Sherwood, Christopher R. (Elsevier B.V., 2007-05-26)
      For more than a century, studies of sedimentology and sediment transport have measured bed-sediment grain size by collecting samples and transporting them back to the laboratory for grain-size analysis. This process is ...
    • Using a composite grid approach in a complex coastal domain to estimate estuarine residence time 

      Warner, John C.; Geyer, W. Rockwell; Arango, Hernan G. (Elsevier B.V., 2010-04-18)
      We investigate the processes that influence residence time in a partially mixed estuary using a three-dimensional circulation model. The complex geometry of the study region is not optimal for a structured grid model and ...
    • Variability of bed drag on cohesive beds under wave action 

      Safak, Ilgar (MDPI AG, 2016-04-01)
      Drag force at the bed acting on water flow is a major control on water circulation and sediment transport. Bed drag has been thoroughly studied in sandy waters, but less so in muddy coastal waters. The variation of bed ...
    • Variational analysis of drifter positions and model outputs for the reconstruction of surface currents in the central Adriatic during fall 2002 

      Taillandier, V.; Griffa, A.; Poulain, P. M.; Signell, Richard P.; Chiggiato, Jacopo; Carniel, Sandro (American Geophysical Union, 2008-04-04)
      In this paper we present an application of a variational method for the reconstruction of the velocity field in a coastal flow in the central Adriatic Sea, using in situ data from surface drifters and outputs from the ROMS ...
    • The vertical structure of the circulation and dynamics in Hudson Shelf Valley 

      Lentz, Steven J.; Butman, Bradford; Harris, Courtney K. (John Wiley & Sons, 2014-06-11)
      Hudson Shelf Valley is a 20–30 m deep, 5–10 km wide v-shaped submarine valley that extends across the Middle Atlantic Bight continental shelf. The valley provides a conduit for cross-shelf exchange via along-valley currents ...
    • Water level response in back-barrier bays unchanged following Hurricane Sandy 

      Aretxabaleta, Alfredo L.; Butman, Bradford; Ganju, Neil K. (John Wiley & Sons, 2014-05-02)
      On 28–30 October 2012, Hurricane Sandy caused severe flooding along portions of the northeast coast of the United States and cut new inlets across barrier islands in New Jersey and New York. About 30% of the 20 highest ...
    • Wave-current interaction in Willapa Bay 

      Olabarrieta, Maitane; Warner, John C.; Kumar, Nirnimesh (American Geophysical Union, 2011-12-13)
      This paper describes the importance of wave-current interaction in an inlet-estuary system. The three-dimensional, fully coupled, Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST) modeling system was applied in ...
    • A wetting and drying scheme for ROMS 

      Warner, John C.; Defne, Zafer; Haas, Kevin A.; Arango, Hernan G. (Elsevier B.V., 2013-05-24)
      The processes of wetting and drying have many important physical and biological impacts on shallow water systems. Inundation and dewatering effects on coastal mud flats and beaches occur on various time scales ranging from ...
