MEDSLIK-II: Status and methodology for inclusion of upgrades in the model code M. De Dominicis

OUTLINE MEDSLIK-II general description Status of the MEDSLIK-II development Toward MEDSLIK-II V1.02

MEDSLIK-II general description The oil spill model code MEDSLIK-II, based on its precursor oil spill model MEDSLIK is a freely available community model  MEDSLIK-II uses a Lagrangian representation of the oil slick  MEDSLIK-II predicts the transport and oil transformation processes due to complex physical processes occurring at the sea-water interface  MEDSLIK-II includes a proper representation of high frequency currents, the wave induced currents and wind fields in the advective components of the Lagrangian trajectory model

HOW TO USE THE CODE!

Forecast of oil spill transport and transformation OCEANOGRAPHIC EULERIAN MODELS ( Currents, Sea Surface Temperature) MEDSLIK-II ADVECTION-DIFFUSION + TRANSFORMATION PROCESSES ATMOSPHERIC EULERIAN MODELS (Winds) Waves

ADVECTION - DIFFUSION TRANSFORMATIONS Advection-diffusion is solved using a Lagrangian approach: the oil slick is discretized by PARTICLES, which are TRANSPORTED by the water currents, waves and the turbulent diffusion. Transformation processes are solved considering the entire slick volume, subdivided in a thin and thick part (Mackay, 1980).
