Subsidence of Artificial Reefs with Bamboo Foundations on a Soft Seabed

Applied Sciences
The design of artificial reefs must be based on the criteria of both durability and serviceability. In this respect, the seabed subsidence rate related to the weight of the reefs and of their foundation system should be limited.

IDENTIFICATION OF SEAFLOOR HABITATS IN COASTAL SHELF WATERS

, 2008
Modern, high-resolution multibeam sonar systems are capable of mapping acoustic backscattering strength coinciding with fine bathymetry, which improves substantially the capability of sonars to discriminate different types of seafloor habitats.
