FLOW ANALYSIS IN EELGRASS MEADOW WITH OSCILLATION FLOW FIELD

Abstract

 “Submerged Aquatic Vegetation model (SAV model)” using object-oriented programming that enables analysis of the interaction between wave-current and aquatic plants has been developed in the previous studies. In this study, we investigated mass transport under oscillational conditions with eelgrass meadow by using SAV model. Also, we made an attempt to clarify how eelgrass capture dissolved inorganic carbon (DIC) that determines CO₂ partial pressure in water. As a result, it was found that the shorter the length of eelgrass is, the more the stokes drift transport DIC. In addition, it was demonstrated that the net absorption of DIC largely depends on the leaf length of eelgrass, and the effect of waves is secondary compared to uniform flow.
