Simulation of water, movements, mixing and spreading of pollutants in the harbour of Oskarshamn

Abstract

The sediment of a bay or harbour can be severely polluted by earlier human activities. The transport or leakage of polluted matter from the enclosed water body to the open sea is very much dependent on the water transport through the mouth of the bay. SMHI has studied the currents in the harbour of Oskarshamn as a part of an extensive project concerning pollution leakage from the harbour to the open Baltic. The study includes computation of wind driven and fresh water driven currents in a 3-dimensional numerical model.
