ERAMM undertakes studies, expert assessments (as a consultant) and technical assistance to the project manager primarily in the context of port development and coastal protection projects:

- design and dimensioning of maritime and port structures

- hydraulics and sedimentology

- coastal sanitation (discharges at sea) and in ports (environmental diagnostics)

- dredging

- artificial reefs


In these studies, ERAMM still leads with a dual approach that is based on field measurements and observations and on implementation of powerful digital tools developed by CETMEF for applications studying waves, current and transport of sediments. ERAMM has these models:

- REFONDE (turbulence)

- REFLUX (2D currents)

- REFLUX SEDIM (sedimentology)
