PIE LTER trapping capacity of suspended cohesive sediments of subdomains at Plum Island Sound, Massachusetts (numerical simulations).

Abstract: 

Trapping capacity of suspended cohesive sediments of subdomains at Plum Island Sound, Massachusetts (from numerical simulations) are predicted using 2D Delft3D FLOW/MOR model and vegetation module during different stages of tidal height and direction.

Methods: 

We have applied the 2D Delft3D FLOW/MOR model with the vegetation module to Plum Island Sound, Massachusetts, USA.

The suspended sediment was released at four different instants during a spring tidal cycle: at high water level (SH), mean water level during ebb (ME), low water level (SL) and mean water level during flood (MF). The physical parameters of the cohesive sediment were kept uniform with a settling velocity of 0.5 mm s-1, and a critical shear stress for erosion of 0.05 N m-2. Since in all scenarios the suspended sediment mass in the water column after 1 month is negligible, we only measured the sediment mass deposited at the bottom of the different subdomains.
