Abstract: A semi-implicit, control-volume, nonhydrostatic model is presented. Advection is fifth order with respect to space. Boundary conditions and molecular fluxes are also formulated at fourth order with respect to space. ...

Abstract: An ocean flow that has all its scales resolved on a model grid can be more efficiently calculated to within a required accuracy by using high-order numerics than by grid refinement with low-order numerics. The differencing ...

Abstract: A two-dimensional numerical model of the shallow-water equations, with a modified Orlanski-type radiation boundary condition, is applied to study storm surges and tides on the North Queensland coast. The numerical simulations ...
