Detailed Description

English {{currentDetailLanguage}} English

The computational code "DROG3D" developed at North Carolina University (USA) was used to described drogue trajectory, under the influence of the tidal currents. The local tidal and current infonnation was obtaJned from another Finite Element based code which solves the shallow water equations. The predi tion of the oil slick trajectory and its Visual reports are in good agreement and the final 011 location was spotted williin the zone indicatecl by tbe model.

3-DIMENSIONAL DROGUE tracking algorithm for a finite element grid with linear finite elements. DROG3D tracks passive drogues with given harmonic velocity field(s) in a 3-D finite element mesh. 

DROG3D allows particles to be advected horizontally and vertically on a 3D finite-element grid by one or more velocity fields using a fourth-order Runge–Kutta integration scheme.

For principles and details on the DROG3D model, see the literature: "Prediction of trajectory and fate of the Nissos Amorgos oil spill".
