Oil spill modelling
ELEGY can provide its clients with Trajectory and Fates models in addition to stochastic modeling which is used for contingency planning.
The trajectory and fates model predicts the transport and weathering of oil from instantaneous or continuous spills. Predictions show the location and concentration of the surface and subsurface oil versus time. The model estimates the temporal variation of the oil’s spatial coverage, oil thickness, and oil viscosity. The model also predicts the oil mass balance or the amount of oil on the free surface, in the water column, evaporated, on the shore, and outside the study domain versus time. The fate processes in the model include spreading, evaporation, entrainment or natural dispersion, and emulsification. On the other hand, the stochastic model generates multiple simulations within a time window to determine the most likely paths released oil would follow under the influence of winds and currents.
