Dispersion models

   
 
 

The Lagrangian Dispersion Model and the Eulerian Dispersion Model are operated by the BSH


Where does my message in a bottle drift to?
Where did the flotsam come from, which I found at the beach?
How substances and objects move in the sea is in many cases essential, e.g. in
  • Contingency planning for oil averages
  • Investigations leading to the possible origins of observed marine pollutions
  • Evaluations of potential endangerments, e.g. by averages in shipping routes
  • Search and Rescue operations
  • Reconstruction of maritime accidents (after finding related persons/objects)
  • Search and salvage operations of lost objects or buoyage and warning of the shipping
  • Prediction of environmental pollutions and warning of the population (e.g. algae blooms)
  • Planning of monitoring expeditions for given circumstances (e.g. Elbe flooding)
It is the task of the BSH to deliver such dispersion predictions and backtracking calculations for internal purposes as well as on request to other authorities, administrations and the prosecuting authority resp. the police. For this purpose the BSH uses either the Eulerian or the Lagrange dispersion model. The results are delivered within shortest time lag, even any time of day or night depending on the kind of request. This is for example the case in oil averages.
