IMPACT : Port economic development and environment


PI : Marcello Magaldi (CNR ISMAR)


Partners : CNR ISMAR (PI, It), LaMMA (It), CIBM (It), Tuscany Region (It), IFREMER (Fr), LECOB CNRS (Fr), University of Toulon (Fr)

Head of the University of Toulon : Yann Ourmieres (MIO)


Objectives of the project

  • Understand how to reconcile the economic development of Mediterranean industrial ports with their proximity to marine protected areas.
  • Understand the impact of port activity in terms of pollution on an adjacent marine protected area
  • Consolidate environmental knowledge, develop monitoring methodologies


Selected workshop sites

  •  Bastia / Cap Corse Marine Park (site monitored by IFREMER)
  •  Rade de Toulon / Parc National de Port-Cros (site monitored by the University of Toulon)
  •  La Spezia / Cinque Terre (site monitored by CNR ISMAR)
  •  Livorno / Secche de la Melloria (site monitored by the LaMMA consortium)


Numerical and experimental strategy

  • Numerical modeling :
    • High resolution for the entire area to better understand the mass water exchanges between the 2 bays
    • Very high resolution for the Toulon harbour to better simulate the 3D mixing of water masses and thus the transport of pollutants
  •  In-situ current measurement to complete / validate model simulations
    • Deployment of geolocatable drifting buoys
    • Deployment of ADCP (current meters)

Modeling the transport of dissolved contaminants (here, copper) in the Toulon harbour in different wind conditions. Up and down: weak mistral, strong mistral, weak East, strong East.
