Okey G. Nwogu, Ph.D.

Research Interests

Nearshore Wave Hydrodynamics 

Mathematical modeling of wave propagation in coastal regions, Boussinesq equations, nonlinear wave-wave interactions in shallow water, wave breaking and breaking-induced turbulence in the surf zone, rip currents, longshore currents. 

Wave-Structure Interaction 

Mathematical modeling of the motions of large offshore structures in irregular multidirectional waves, mathematical modeling of the motions of ships in navigation channels and harbors, time-domain modeling of the dynamic response of slender compliant structures, laboratory model studies of oil production platforms. 

Ship-Generated Waves 

Mathematical modeling of waves and currents generated by  large deep-draft vessels in confined waterways, wake wash from high-speed vessels, ship-ship and ship-bank interaction, water-level drawdown and return currents in confined channels, vessel squat in shallow water. 

Wave Propagation in Harbors

Wave refraction, diffraction and reflection in ports and harbors, infragravity wave generation in shallow water, long-period resonant harbor oscillations. 

 

Sediment Transport 

Advection-diffusion modeling of suspended sediment transport in the surf zone, beach erosion processes.
