What is the effects of seagrass beds (posidonia in Mediterranean Sea) in the nearshore zone:
- on wave attenuation;
- on suspended sediment transport?
How can we configure to test the effects of posidonia in a coupled hydrodynamic-sediment transport 2D (Mike 21)?
A few suggestions for papers, if you don't already have them:

Hello,
Here you can find several paper about wave damping over Posidonia oceanica meadow:

The effect of the seagrasses on the sediment consists in the changes sediment transport. Besides, it also affects the optical properties of the water column. Thus, when the sunlight enters the water column and goes down, parts of the electromagnetic energy are absorbed and scattered, which is determined by the optical and physical properties of the water. For example, concentration of suspended particles, chlorophyll, coloured dissolved organic matter that make up the water content. You can read more on P.oceanica modelling using WASI in my thesis:
