E. D. de Goede, A Numerical Model of the Northwest European Continental Shelf on the CRAY Y-MP2E, IMPACT of Computing in Science and Engineering 5, 1-19 (1993).

A numerical model for the shallow water equations in polar coordinates is applied to the Northwest European continental shelf. A three-dimensional model of the continental shelf is presented. A simulation is carried out for the period of 9 to 12 February 1989. The same continental shelf problem has been examined by Leendertse. The numerical results are in good agreement with each other. It appears that the amplitude and phase errors are small. We also describe a comparison with a two-dimensional model of the continental shelf. The time splitting method used in this paper consists of two stages and is unconditionally stable. Moreover, it can fully exploit vector and parallel facilities of supercomputers. Three-dimensional shallow water models require great computational effort and it is therefore necessary to use such fast computers. The numerical experiments were carried out on the one-processor CRAY Y-MP2E of ICIM (Informatics Centre for Civil Engineering and Environment). This supercomputer was recently installed in the Netherlands for the simulation of large scale models of rivers and seas. 1993 Academic Press. Inc.
