A NEW APPROACH TO 3D FLOW AND TRANSPORT-MODELING

Johan C.M. Dijkzeul, Jan J. Leendertse

Abstract


In recent years two-dimensional numerical models have been applied successfully not only to large scale tidal computations, but also to small scale detailed flow computations (Bosselaar et al., 1987, Leendertse et al., 1989). However the application of three-dimensional models for fine-grid computations is very limited due to the very high requirements for computer times, caused by the explicit numerical algorithms which are being used. This problem is now alleviated by use of an alternating direction implicit computation method for threedimensional flow- and transport-modeling. With this method, presented in this paper, the effective computation time is about an order of magnitude smaller then with previous models with similar accuracy.
