WATER EXCHANGE AND DISPERSION MODELLING IN COASTAL REGIONS: A METHOD STUDY
A high resolution hydrodynamic model is used to estimate fluxes between boxes in a coarse compartment model. The latter model may include complex biogeochemical processes, here exemplified by dispersion of radionuclides released from a nuclear power plant. The water recipient – Öregrund Grepen – is assumed non-stratified and the circulation to be mainly winddriven. The calculations based on three typical circulation patterns, forced by three different winds, yielded considerably higher exchange rates and lower concentrations than the results from an earlier compartment model based on mean conditions.
