A Hydrodynamic Model for the Transport of a Conservative Pollutant

Part of the Marine Science book series (MR, volume 7)


A hydrodynamic model was developed for calculating the transport of a conservative contaminent, and the model has been used for determining the movement of oil slicks in several water bodies in Canada. At present, this model does not consider the structural properties of crude oil (mainly because observations showed that the hydrodynamic forces are at least an order of magnitude greater than the internal spreading forces), but is limited to the dynamics of surface waters. The following forces are included: (1) the effects of periodic or quasi-stationary water currents such as tides or hydraulic channel flows, (2) the effects of organized atmospheric wind systems and the resulting systematic displacements of surface waters, (3) the effects of quasi-random disturbances in wind fields or current patterns with the resulting non-uniform spreading of the oil patch. The topography of the water body, the tidal currents and the climatological data can be stored in a computer data bank, whereas the meteorological data has to be obtained in real time. Secondary factors such as internal spreading forces, stratification and the influence of an ice layer are being included in an approximate manner. In this paper, the discussion is centered on the inclusion of these secondary factors.
