MUMM studies the ecosystem of the North Sea using mathematical modelling techniques.

A hydrodynamic model describes the distribution of three-dimensional currents and the height of the surface of the sea. A second model describes the distribution of waves in the North Sea. A third model describes the movement, spreading and physical and chemical development of pollutants on the surface of the sea, particularly hydrocarbons. It is used in every critical or accidental situation to determine the potential impact of pollution and provide support for the decisions to be taken in the operations to fight pollution. These models are inter-linked.

Transport and evolution model of slicks:

To be run,the model needs on input,

- the spill coordinates

- the spill volume

- the bathymetry (coastline)

- the fields of water current speed and of wind speed in the area of interest

- some characteristics of the oil or of the chemical (i.e. specific mass, surface tension molecular weight, vapour pressure, cinematic viscosity, emulsification, capability and evaporate fraction)

The model provides hourly information about the slick position, the slick shape and the characteristics of the oil.

Geographical coverage:

The transport module can also be used to estimate the drift of any floating device.
