Summary: Coastal areas adjacent to tidal inlets are valuable areas that are influenced by complex nearshore bathymetry and wave-tidal forcing interactions. However, the understanding of these interactions is often limited by the lack of a systemic approach and comprehensive datasets. By using different datasets and satellite imagery, a comprehensive understanding of tidal inlets dynamics and their control on downdrift coasts can be developed.

Summary: This article proposes two techniques for studying the dynamics and preservation potential of ebb-tidal deltas using high-resolution bathymetric surveys. The first technique involves conformal mapping to polar coordinates to visualize and quantify the morphodynamic behavior of deltas. The second technique involves generating a stratigraphic model from the differences between successive bathymetries. These techniques provide valuable insights for coastal management and interpreting ancient rock records.

Summary: Detailed observations and analysis of ebb-tidal delta dynamics and interactions with shorelines are crucial for barrier island management. The intra-delta dynamics of Ameland Inlet in the Netherlands have undergone significant changes over 15 years, with sand transport between islands leading to channel relocation.

Summary: This study investigates the impact of tidal range and wave conditions on the generation of overtides through numerical simulations. The results suggest that increasing wave height amplifies overtide current velocities, while changes in wave period and direction have a lesser effect. The mechanisms of bottom stress, pressure gradient, and bottom wave streaming are identified as key factors in enhancing overtide generation.

Summary: In response to climate change and sea-level rise, new nourishment strategies have been developed for low-lying sandy coasts, which can affect the habitat quality of coastal ecosystems. By studying the relationship between benthic fauna and their environment, researchers can design sustainable management strategies for these ecosystems. A unique dataset of benthic and sediment samples collected at the ebb-tidal delta of Ameland, The Netherlands allowed for an investigation into the distribution of macrobenthic fauna and its correlation with morphological features. The findings revealed distinct species assemblages along gradients of physical stress and exposure, which were reflected in the sediment characteristics. Additionally, the functional characteristics of the benthic fauna showed clear contrasts between exposed and sheltered areas, suggesting different recovery rates in response to disturbance.

Summary: The tidal prism of the Lignano tidal inlet has remained relatively constant over the past forty years, despite a decrease in section width. A sensitivity analysis was conducted using a conceptual scheme of the sea-channel-lagoon system, revealing three regimes of prism variability. The study also investigated the impact of inlet and channel sizes on prism value.

Summary: This study quantified the structural and functional connectivity of Suaeda salsa in the Yellow River Delta and found that plant structural connectivity increased with distance inland, while seed connectivity was enhanced but gene connectivity was diminished when moving inland. The impact of tidal action on connectivity was inconsistent, with tidal channel branching rate reducing plant structural connectivity and tidal inundation frequency promoting gene connectivity. Tides can promote effective plant connectivity, but temporal and spatial scales should be considered in studying plant connectivity.

Summary: This study explores the performance of different inundation models built with the 2DH surfbeat solver of XBeach. The results show that improving numerical diffusion and breaking criteria are beneficial for model performance, and handling the short-wave directional spectrum at the open boundary helps to predict overtopping. Increasing cross-shore resolution and reducing the friction coefficient also improve the representation of observed inundation extents. Additional phase-resolving simulations in 1DH overestimated IG wave energy and produced higher and more frequent overtopping discharges.

Summary: The study revealed the significant impact of paleoclimate on the morphology and depositional processes of shoal-water deltaic systems, distinguishing between early humid and later arid climatic stages to define deltaic sedimentary sequences and propose conceptual depositional models analogous to modern lake and river deltas.

Summary: This study aims to identify coherent trajectory patterns caused by vortex shedding in tidal environments, and single and multiple harmonics tides are replicated on a large-scale physical model. The dynamics of large-scale macro-vortices and stable and unstable manifolds within the flow are investigated using the Lagrangian Average Vorticity Deviation (LAVD) and Finite Time Lyapunov Exponents.

Summary: Shoal water deltaic sand bodies are crucial hydrocarbon reservoirs, but their complex distribution patterns pose challenges in reservoir characterization and exploration. Studying modern and ancient shoal water deltaic deposits, especially jet plume related deposits, can provide new insights for reservoir characterization.

Summary: A time-domain Boussinesq model was used to study wave interference and its effects on nearshore circulation. The model predicted interference phenomena and small-scale flow structures tied to wave modulation patterns. The alongshore currents were influenced by pressure gradient forces associated with wave setup variation.

Summary: This review investigates the complex relationship between cardiac lymphatics, myocardial edema, and cardiac disease. It covers the revised paradigm of microvascular forces and fluid movement, as well as the preclinical tools and animal models used to study myocardial edema and cardiac disease. Clinical studies and recent animal studies on the role of cardiac lymphatics in cardiovascular disease models are analyzed. The outstanding questions regarding the roles of cardiac lymphatics in health and disease are highlighted.

Summary: The construction of dams in the estuaries in the southwest Netherlands caused significant morphodynamic changes in the ebb-tidal deltas, leading to erosion, formation of sand bars, and reduction in average depth. The extension of the port of Rotterdam increased sand supply and eventually led to the breach of the shore-parallel bar. A three-stage conceptual model was developed to summarize the observed development of ebb-tidal deltas, which can help assess interventions in estuaries and tidal inlets for sea-level rise mitigation.

Summary: The paper presents an optimal control strategy for maximizing the extracted mechanical power by controlling the tidal flow through a channel connecting two basins with different tidal regimes. The control strategy is determined as a function of the blockage ratio, s, and is based on the energy equation and the relative volume flow. The results provide a physically consistent generalization of previous research and offer advantages in terms of concise analytical solutions and reduced complexity of the control task for turbine arrays.

Summary: This study examines the effect of dune dynamics on sediment flux and shows that variations in dune migration lead to fluctuations in flux. The feedback between bed morphology and water surface slope causes changes in dune shape, and the interaction between dunes influences flux patterns. However, estimating the contributions of dune migration to flux remains challenging, even with detailed data.
