Modelling the dynamics of a large sea area

Abstract

The dynamics of the Bothnian Bay was studied mainly by means of numerical models. The model results were supported by flow velocity measurements and by water quality components sampled for more than twenty years in the research area. Prior to the study an extensive review was made on the model usage abroad. The main tools of the project, 3-dimensional (3D) current and water quality models were developed in many aspects. An efficient 2D multigrid model for flow fields and an automatic grid generation program were developed for applications where good horizontal resolution is needed over large sea areas. The success in computing the surface currents was tested in several cases (oil accident, drifting of objects). As a local application of the models, the effects of different loading alternatives on the water quality off the town of Kemi was calculated. Based on model results and measurements a proposal was made to develop the water quality monitoring program.
