“…This approach enhances our ability to understand sediment transport dynamics, identify areas prone to excessive deposition, and inform sustainable coastal resource management strategies. Relevant literature supports the efficacy of satellite imagery in monitoring coastal sediment dynamics, including studies by Li et al, (2024); Pandey et al, (2016); Cudahy et al, (2016); Dethier et al, (2022); Dethier and Renshaw, (2020); Wagh and Manekar, (2021); Best, (2019); Mouyen et al, (2018);and, Nagel et al, (2023) highlighting its utility in coastal management decision-making processes. Interestingly, Bendô et al, (2023) emphasizes the effectiveness of hydromorphodynamic modeling, focusing on dredge-and-dump strategies, to enhance natural mechanisms, positively impacting channel depth and stability, while also enabling prediction of adverse changes in physical parameters over the medium and long term.…”

“…Obtaining sediment elevation data from both field sampling and satellite imagery is crucial for enriching the scientific community's understanding of spatial sediment patterns. While field sampling provides direct measurements at specific locations (Li et al, 2024;Nagel et al, 2023;Wagh and Manekar, 2021;Cudahy et al, 2016;Stevens et al, 2023), satellite imagery offers a broader spatial coverage, allowing for the observation of sediment dynamics across larger areas, including transition zones and river channels. Integrating these two sources of data provides a comprehensive picture of sediment distribution and movement, enabling more robust spatial pattern analysis.…”

This research explores sediment deposition patterns in coastal areas by employing synthetic data representing wandering set and recurrent patterns, utilizing Fourier transformation and power-law analysis to characterize frequency content and scaling behavior. The study employs fundamental models to interpret observed patterns and investigates the relevance of Poincaré's theorem in understanding recurrent patterns. Leveraging Python-based computation systems and open-source satellite data, the findings reveal contrasting behaviors in power-law exponents between scenarios, with wandering set patterns exhibiting scale-free characteristics and recurrent patterns displaying structured frequency distributions. This holistic approach advances scientific knowledge on sediment dynamics, informing evidence-based decision-making for effective sediment management and coastal resilience planning. Through its methodology and insights, the research contributes to understanding sediment deposition processes, elucidating underlying mechanisms driving coastal sedimentation, and providing practical approaches for monitoring and studying sediment dynamics in coastal environments, ultimately enhancing strategies for coastal management and conservation.

Lateral connectivity between rivers and terrestrial landscapes is critical for both river and landscape health. Due to widespread anthropogenic degradation of riverscapes, river management is aiming to connect rivers to floodplains, riparian zones, and wetlands, putting a spotlight on lateral connectivity. However, there is currently no consensus on how to conceptualize and study lateral connectivity in rivers across disciplines. Here, we review lateral connectivity between riverscapes and terrestrial landscapes. We focus on the natural sciences, considering hydrology, geomorphology, ecology and biogeochemistry, but also consider social connectivity and the management and restoration of lateral connectivity. We emphasize the importance of considering the bidirectional nature of lateral connectivity, operating both into and out of river channels and the balance between these directions. The resulting “lateral connectivity balance” provides a framework to understand natural spatial and temporal variability in connectivity. Anthropogenic impacts have swung the balance of lateral connectivity, enhancing the transport of materials into and through river networks while suppressing fluxes from rivers to adjacent landscapes. We conclude that further research at the interfaces between the aquatic and terrestrial components of riverscapes is critical to advance our conceptual understanding of river and catchment systems. We propose that such research should be framed within the paradigm of “rebalancing” lateral connectivity, explicitly recognizing the natural bidirectionality of laterally connecting processes, the significance of the hydrologic, geomorphic, and biologic functions they support, and the value to society of the ecosystem services and climate change resilience they provide.
