ABSTRACT
Mathematical models of the North Sea have been developed in most of the bordering countries. The mathematical model which emerges from the confrontation with the database is submitted to the scientific reflection. In an earlier stage, the models tended to address separately the Physics, the Chemistry and the Biology of the North Sea. Now, the development of computing facilities allowing more ambitious programs, these models are progressively integrated in a common, general, interdisciplinary model with the purpose of understanding the North Sea environment, predicting its evolution, taking into account the constraints of Modern Society, and assisting its management. The Southern Bight model can predict with great accuracy the elevation of the water surface produced by tides and storm surges, the dispersion, sedimentation of suspended material as well as the final deposition of sediments on the bottom.
