Water Flow in Seagrass Ecosystems - Hydrodynamic environment of seagrass meadows

The hydrodynamic environment within the seagrass canopy of Amphibolis griffithii, Posidonia australis, Posidonia sinuosa and mixed Posidonia beds was studied, and compared with a bare sand site (See thumbnail). Electronic current meters developed by the author (Chapter 2 of thesis) was used to measure water velocity profiles. In addition, the hydrodynamic regimes of sheltered and exposed Posidonia sinuosa sites were studied, as well as sediment size fraction distribution within a dense Posidonia sinuosa meadow. These studies were undertaken in Shoalwater Bay located south of Perth, Western Australia.
