PRESEN has a proven experience in the hydro-sediment transfers field (in the continent-sea continuum) which relies on high-frequency approaches from the watershed continuum to the near-coastal area.

The platform is equipped with an instrumental range dedicated to in situ parameters measurement in order to allow the understanding of the processes related to hydrodynamic and sediment transport, in the context of long- term measurements acquisition . This instrumental range is associated with specific means of implementation and logistic equipments, easily transportable and designed for  campaigns on international or workshop sites .

This technical platform works with powerful tools of processing and validation data :

• Statistical processing
• Geographic Information System (GIS)
• DTM (Digital Terrain Model)
