Depth Reduction

In shallow water, particularly near the coast, the hydrodynamics are influenced by bottom friction which, increases with depth reduction and the complexity of the sea floor, mostly in the presence of vegetation. Although little is still known about the seagrass capability to reduce wave energy, it is known to increase the sediment stability in anthropogenically disturbed areas; hence the interest of evaluating their efficiency as a means for coastal protection.

Perforated Caisson

An innovative caisson breakwater geometry (patent pending) named "ARPEC" (Anti Reflective PErmeable Caisson) includes openings at all external and internal walls and at lateral (cross) ones, yet in a staggered pattern, to provide a labyrinthian hydraulic communication between the open sea and the internal waters. The complex sinuous water-flow within the consecutive permeable chambers thus favors wave energy dissipation as well as port water flushing and quality, with very low reflection and transmission coefficients. 2D lab model tests demonstrate the system effectiveness.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/PaUsinYO-Zo
