“…Thus, areas that create heterogeneous substrates, such as flow transition areas, may be important for identifying relocation or restoration sites. Furthermore, sediment characteristics can represent flow and turbulence (Lazzarin et al, 2023), both of which are components that structure mussel habitat but are relatively complex features to measure over longer timespans.…”

Freshwater mussel species regularly co‐occur in streams forming assemblages, but the extent of shared versus unique instream habitat features that contribute to their distribution and abundance is poorly understood. In Massachusetts, a rare species, Alasmidonta varicosa, is often found with four other species: Alasmidonta undulata, Strophitus undulatus, Margaritifera margaritifera, and Elliptio complanata, yet variation in species composition within assemblages raises questions of potential species‐specific habitat associations. Identifying species‐level habitat information is critical at a spatial scale that malacologists can use to identify translocation or restoration areas. This study investigated whether species abundance varied by mesohabitat type (riffle, run, dam pool, scour pool), instream habitat characteristics, and within‐reach location (centre versus edge). From 2016 to 2019, freshwater mussel surveys were conducted in nine streams across Massachusetts and associated habitat information was collected. Species abundances were similar across mesohabitat types. Elliptio complanata was the exception, whereby higher abundances occurred in runs and dammed pools than in riffles. Unique species relationships with habitat existed for M. margaritifera with macroalgae and emergent vegetation, and A. varicosa with heterogeneous substrate. Flow transitions, such as depositional areas that create heterogeneous substrates, may provide habitats for A. varicosa. Most mussel species were distributed with higher abundance in the river centre than the edge; E. complanata was the only species with a higher abundance at the river edge. Locations with high abundance varied based on unique relationships with pebble heterogeneity (A. varicosa), depth (A. undulata), large wood (A. undulata), and canopy closure (E. complanata). Including physical characteristics in a holistic assessment of habitat that incorporates fish and landscape attributes may further an understanding of river reaches that best support translocated and propagated freshwater mussels.

“…Eddy-resolving turbulence models such as LES (Constantinescu et al, 2013) and DES (Lazzarin et al, 2023) were used to simulate the flow around mussels. However, compared to the previous study, the individual mussels in this study were significantly smaller and their attachment was much denser, resulting in increased computational requirements.…”

“…When the density of Lampsilis siliquoidea exceeded 25 mussels/m 2 on the wall surface, the turbulent shear stresses acting on the mussels were reduced by up to 64% (Sansom et al, 2020). The study of the flow field structure around the mussels revealed that vortex structures were formed around the mussels, which increased the wall shear stress and induced local scour in front and behind the mussel (Lazzarin et al, 2023). In most studies of mussel roughness, the studied species were much larger than LF, thus the pervious findings may be not applicable for LF.…”

“…Nevertheless, the changes in flow resistance due to LF attachment increase the unpredictability of hydraulic calculations for open channels, which posed a great potential threat to the operation of water transfer projects. Some hydrodynamic variables, such as velocity (Zhang et al, 2020), wall shear stress (French & Ackerman, 2014), and vortex structure (Lazzarin et al, 2023) were used to describe the impact of mussel attachment on the flow field (Hardison & Layzer, 2001;Allen & Vaughn, 2010;Lopez & Vaughn, 2021). However, the quantification of the flow resistance due to LF attachment structures remains unresolved.…”

“…By resolving the complex geometric structures of the aquatic organisms, forces acting on the objects as well as the local flow structures could be accurately predicted (Xu & Liu, 2017;Chen et al, 2018;Lazzarin et al, 2023). Therefore, high-resolution geometric models are crucial to ensure the accuracy of numerical simulations.…”

High-density attachment of Limnoperna fortunei (LF) would lead to the increase of flow resistance, which has posed big challenges to the normal operation of water conveyance projects. It is very necessary to quantify the flow resistance caused by the attachment of LF. In this study, a 3D geometric model of LF was generated based on real images. Attachment models of LF were generated with different densities and mussel size distributions, whose geometric characteristics were evaluated by some fundamental physical quantities, including attachment thickness, bed coverage, surface vertical roughness, and roughness concentration. Furtherly, a 3D numerical model with specific boundary conditions was established in OpenFOAM to simulate the flow over the LF attachment. Body-fitted mesh was generated using snappyHexMesh based on the LF attachment model. The results show that in high-density scenarios, a big wake zone formed inside LF attachment by the combined effects of each individual LF. Turbulence kinetic energy distribution indicated that LF attachment would cause viscous dissipation thus leading to more energy loss. The flow structure inside LF attachment was controlled by the size and spacing between each individual LF. Manning’s n values were calculated based on the CFD results at different densities. The results show that the flow resistance of LF attachment also followed the classic flow regimes, where in the skimming flow regime, the mussel size distribution played a non-negligible role. Higher flow speed resulted in larger flow resistance, and n could increase more than 90% compared to the scenario without LF attachment.
