Persistency of debris accumulation in tidal estuaries using Lagrangian coherent structures

The Role of Fronts in Horizontal Transports of the Changjiang River Plume in Summer and the Implications for Phytoplankton Blooms

“…The LCSs analysis has been applied to many oceanic research areas, including open ocean (Duran et al., 2018; Harrison & Glatzmaier, 2012), continental shelves (Dong et al., 2021; Hu & Zhou, 2019), and coastal and estuarine waters (Ghosh et al., 2018; Ghosh, Suara, Mccue, & Brown, 2021; Giudici et al., 2021; Suara et al., 2020; Wei et al., 2013), which provides a useful tool to investigate the accumulation and transport of material. The LCSs method was also used to study the interactions between physical processes and biogeochemical processes, such as the persistency of debris accumulation in estuaries (Ghosh, Suara, Mccue, Yu, & Brown, 2021), the development and dispersion of algal blooms (Olascoaga et al., 2008; Son et al., 2016), and the track of marine predators (Kai et al., 2009). Compared to traditional Lagrangian particle tracking techniques, which are focused on predicting the trajectories of individual particles and hardly resolve the full‐field transport information (Peacock & Haller, 2013), LCSs concentrate on the interactions of different fluid particles, which thus reveal the transport characteristics and the corresponding dynamical structures considering the field as a whole (Ottino, 1989; Wiggins, 1993).…”

Lagrangian analysis of material transport around the headland in the Yellow River Estuary

“…By contrast, as a locally strongest repelling or attracting material surface (Haller and Yuan, 2000), LCSs are robust features of Lagrangian fluid motion. In recent years, LCS has been widely used to study the structures of flow fields in the ocean, atmosphere, and human blood (Nolan et al, 2019;Ghosh et al, 2021;Mutlu et al, 2021), as well as transport and mixing structures near the islands and headlands (Suara et al, 2020). In this study, the three Lagrangian approaches are combined to describe the transport and diffusion characteristics of the material in YRE.…”
