This article aims to discuss the notion of environmental damage under the CLC 1992 and FUND 1992 as stated in the new Guidelines for Presenting Claims for Environmental Damage prepared by the International Oil Pollution Compensation Funds. That approach is contrasted with the solution adopted in the United States of America under the OPA. Particular attention is given to the problems of compensation for lost services of the environment, as well as providing alternative environment as a restoration measure. The judgments of French and Spanish courts in the Erika and Prestige cases are discussed, raising questions as to suitability of the CLC 1992/FUND 1992 system.
In the paper, the authors discuss the construction of a model of an exemplary urban layout. Numerical simulation has been performed by means of a commercial software Fluent using two different turbulence models: the popular k-ε realizable one, and the Reynolds Stress Model (RSM), which is still being developed. The former is a 2-equations model, while the latter – is a RSM model – that consists of 7 equations. The studies have shown that, in this specific case, a more complex model of turbulence is not necessary. The results obtained with this model are not more accurate than the ones obtained using the RKE model. The model, scale 1:400, was tested in a wind tunnel. The pressure measurement near buildings, oil visualization and scour technique were undertaken and described accordingly. Measurements gave the quantitative and qualitative information describing the nature of the flow. Finally, the data were compared with the results of the experiments performed. The pressure coefficients resulting from the experiment were compared with the coefficients obtained from the numerical simulation. At the same time velocity maps and streamlines obtained from the calculations were combined with the results of the oil visualisation and scour technique.
