TLDR
In this paper, the authors discuss the morphodynamics of different units that characterize a tidal inlet system: the overall system, the ebb-tidal delta, the tidal channels, channel networks, tidal bars and meanders, and finally the intertidal zone of tidal flats and salt marshes.Abstract:
In this review we discuss the morphodynamics of tidal inlet systems that are typical of barrier coasts formed during a period of continuous sea-level rise during the Holocene. The morphodynamics concerns feedbacks between three major components: the hydrodynamics of tidal currents and wind waves; the erosion, deposition, and transport of sediment under the action of the former hydrodynamic agencies; and the morphology proper, which results from the divergence of the sediment transport. We discuss the morphodynamics of the different units that characterize a tidal inlet system: the overall system, the ebb-tidal delta, the tidal channels, channel networks, tidal bars and meanders, and finally the intertidal zone of tidal flats and salt marshes. In most of these units, stability analysis is a major guide to the establishment of equilibrium structures.read more

Landscape evolution in tidal embayments: modeling the interplay of erosion, sedimentation, and vegetation dynamics
TL;DR: In this article, an ecomorphodynamic model was proposed to investigate the response of tidal morphologies to different scenarios of sediment supply, colonization by halophytes, and changing sea level.

Review of wave‐driven sediment resuspension and transport in estuaries
Malcolm O. Green,Giovanni Coco +1 more
TL;DR: A review of wave-driven sediment resuspension and transport in estuaries, including generation of bed shear stress by waves, initiation of sediment motion by waves and the ways waves modulate, add to, and interact with sediment transport driven by currents, can be found in this paper.

Sediment Trapping in Estuaries.
TL;DR: A transport decomposition is used to present processes that lead to convergent SPM transport, and trapping mechanisms that leading to ETMs at the landward limit of the salt intrusion, in the freshwater zone, at topographic transitions, and by lateral processes within the cross section are reviewed.

The Effect of Tidal Asymmetry and Temporal Settling Lag on Sediment Trapping in Tidal Estuaries
TL;DR: In this article, a 2DV model is developed to investigate the changes in relative roughness (friction) and mixing, resulting in fundamental changes in the char- acteristics of the horizontal (velocity) and vertical tides (sea surface elevation).

Tidal flat morphodynamics: a synthesis
TL;DR: In this article, the authors studied the morphology and evolution of a set of features such as profile shape, bed slope, and grain size as a function of sediment supply and wave and tidal forcing, and the nature of wave and tide-induced velocities across tidal flats.

Radiation stresses in water waves; a physical discussion, with applications
TL;DR: The radiation stresses in water waves play an important role in a variety of oceanographic phenomena, for example in the change in mean sea level due to storm waves (wave set-up), the generation of "surf-beats", the interaction of waves with steady currents, and the steepening of short gravity waves on the crests of longer waves as discussed by the authors.

Waves in Oceanic and Coastal Waters
TL;DR: The SWAN wave model as discussed by the authors is a wave model based on linear wave theory (SWAN) for oceanic and coastal waters, and it has been shown to be effective in detecting ocean waves.

Morphodynamics of Holocene salt marshes: a review sketch from the Atlantic and Southern North Sea coasts of Europe
TL;DR: In this paper, it was shown that the evolution from an organogenic to a sequence of mineralogenic marshes (transgressive overlaps) is accompanied by the initiation and invasive development of a branching network of tidal creeks.
