Flocculation with heterogeneous composition in water environments: A review

Que Nguyen Ho et al.

Summary: Flocculation is a critical process for controlling the fate and transport of suspended particulate matter (SPM) in water environments. However, the lack of comprehensive research on the composition and structure of flocs has led to misconceptions about the dynamics of SPM. This review summarizes the current understanding of the heterogeneous composition of flocs and discusses the effects of human activities on floc composition.

Quantification of 3-dimensional structure and properties of flocculated natural suspended sediment

K. L. Spencer et al.

Summary: This study demonstrates that 2D approaches underestimate the shape complexity and overestimate the size and mass settling flux of natural sediment flocs. This has significant implications for estimating sediment flux in aquatic environments and has the potential to improve the accuracy of current field-monitoring techniques.

Revealing pore connectivity across scales and resolutions with X-ray CT

Maik Lucas et al.

Summary: Connectivity is crucial for quantifying pore structure and soil functions. Different pore types and processes leave distinct characteristics on certain connectivity metrics, requiring a joint evaluation to disentangle them. Scale dependence should be considered for accurate connectivity analysis.

Metal pollutant pathways in cohesive coastal catchments: Influence of flocculation and biopolymers on partitioning and flux

R. J. Schindler et al.

Summary: The partitioning of potentially toxic metals in estuaries is complex and influenced by factors such as salinity and the presence of extracellular polymeric substances (EPS). Salinity was found to be the main factor controlling metal partitioning to sediment, while the flocculation process and the addition of EPS also had significant impacts on metal distribution. Understanding the role of EPS is important for accurate modeling of metal fate in estuarine environments.

Impact of the Water-Sediment Regulation Scheme on the phytoplankton community in the Yellow River estuary

Jingjing Zhang et al.

Summary: The study found that the Water-Sediment Regulation Scheme promoted phytoplankton growth in estuarine areas, but decreased phytoplankton abundance in the entire study area. It also led to a decrease in phytoplankton biodiversity and an increase in abundance of specific species like Synedra sp. Moreover, the scheme resulted in a temporary rapid increase in zooplankton abundance and biomass.

A structure-function based approach to floc hierarchy and evidence for the non-fractal nature of natural sediment flocs

Kate L. Spencer et al.

Summary: Natural sediment flocs are complex structures with behaviors that differ from fractal theory, as new observations of their three-dimensional structures show non-fractal characteristics. Researchers propose a floc hierarchy based on three-dimensional structure and function, offering the opportunity to explore new emergence-based floc frameworks.

Transport of biodeposits and benthic footprint around an oyster farm, Damariscotta Estuary, Maine

Kara Gadeken et al.

Summary: The benthic impact of aquaculture waste is influenced by the accumulation and flow of waste around and below the farm. A study on an oyster aquaculture farm in the Damariscotta River found that despite slightly higher sediment erodibility at the farm compared to a downstream site, similar biogeochemical fluxes, geochemical properties, and macrofaunal communities indicated minimal impact on benthos. The study also observed microalgal mat presence and partial failure under high shear velocity, but suggested that peak bottom velocities during spring tides may periodically clear under-farm sediment of recent deposits.
