Creator:: Newberger, P. A. and Allen, John S.
Abstract:: A three‐dimensional primitive‐equation model for application to the nearshore surf zone has been developed. This model, an extension of the Princeton Ocean Model (POM), predicts the wave‐averaged circulation forced by breaking waves. All of the features of the original POM are retained in the extended model so that applications can...

Creator:: Newberger, P. A. and Allen, John S.
Abstract:: An Eulerian analysis for wave forcing of three-dimensional (3D) wave-averaged mean circulation in the surf zone is presented. The objective is to develop a dynamically consistent formulation for applications in a 3D primitive equation model. The analysis is carried out for the case of shallow-water linear waves interacting with wave-averaged...

Creator:: Wijesekera, H. W., Allen, John S., and Newberger, P. A.
Abstract:: The sensitivity of model-produced time-dependent wind-driven circulation on the continental shelf to the turbulent closure scheme employed is studied with a twodimensional approximation (variations across-shelf and in depth) using the Princeton Ocean Model. The level 2.5 Mellor-Yamada closure (MY), k-ε closure, and K-Profile Parameterization schemes are used to evaluate the...

Creator:: Henderson, Stephen M., Allen, John S., and Newberger, P. A.
Abstract:: We simulated the erosion and accretion of a natural beach using a wave-resolving eddy-diffusive model of water and suspended sediment motion in the bottom boundary layer. Nonlinear advection was included in this one-dimensional (vertical profile) model by assuming that waves propagated almost without change of form. Flows were forced by...

Creator:: Allen, John S., Walstad, Leonard J., and Newberger, P. A.
Abstract:: The finite amplitude nonlinear behavior of the coastal transition zone (CTZ) jet, assumed to be governed by quasi-geostrophic dynamics, is studied utilizing numerical experiments in an idealized geometry. Finite difference solutions to initial value problems are obtained for a stratified, six-layer fluid in a periodic, flat bottom, f plane channel....
