the purpose of this paper is to present a 2d depth-averaged model for simulating and examining unsteady flow patterns in open channel bends. in particular, this paper proposes a 2d depth-averaged model that takes into account the influence of the secondary flow phenomenon through calculation of the dispersion stresses. the dispersion terms which arose from the integration of the product of the ...

Abstract. Eastern boundary upwelling systems (EBUSs) are physically and biologically active regions of the ocean with substantial impacts on biogeochemistry, ecology, global fish catch. Previous studies have used models varying complexity to study EBUS dynamics, ranging from minimal two-dimensional (2-D) comprehensive regional models. An advantage 2-D is that they more computationally efficient...

We propose an efficient model for the description of three-dimensional (3-D) evolution breaking water waves in nearshore region. A fundamental property is its intrinsic ability to account 3-D dynamics vorticity and energy dissipation induced by wave breaking. In particular, achieved through use mollified operators, approach similar spirit that adopted smoothed particle hydrodynamics. Further, s...
