Different oscillations of the sea level are considered, depending on their amplitude and frequency: rapid eustatic fluctuations, energetic tsunamis, storm waves and surges, tides and good weather wind waves.

The present article summarizes the main morphodynamic characteristics of coasts and the resulting environments. Although previous studies suggest that self-organization can emerge from local interactions and can result in increased ecosystem persistence and stability in various ecosystems, our findings extend these concepts to coastal salt marshes, emphasizing the importance of the ecosystem engineers, smooth cordgrass and ribbed mussels, and demonstrating the potential value of self-organization for ecosystem management and restoration.Ĭoastal environments are characterized by their high dynamism, related to the interaction between marine agents (winds, waves, currents, sea level changes) and continental forms and processes. Finally, we find that the presence of mussels in the system modulates the spatial scale of the patterns, generates patterns with shorter wavelengths, and allows the system to tolerate a greater level of erosion. Further, changes in wavelength and variance of the spatial patterns give insight into marsh recession. Spatial self-organization of the marsh edge increases the system’s productivity, allows it to withstand erosion, and delays degradation that otherwise would occur in the absence of strong species interactions. Our model indicates that scale-dependent interactions between multiple ecosystem engineers drive the self-organization of eroding marsh edges and regulate the spatial scale of shoreline morphology. We use a mathematical model to describe self-organization of an eroding marsh shoreline based on three-way interactions between sediment volume and two ecosystem engineers – smooth cordgrass Spartina alterniflora and ribbed mussels Geukensia demissa. Spatial patterning may be one way for them to cope with such changes. As environmental conditions gradually worsen (e.g., resource depletion, erosion intensified by storms, drought), some ecological systems collapse to an irreversible state once a tipping point is reached. Spatial self-organization, a common feature of multi-species communities, can provide important insights into ecosystem structure and resilience. It also considers how human interventions can take advantage of natural processes to enhance or accelerate achievement of natural coastal defense. It discusses how the characteristics of the system adjust to external forcing and how these adjustments affect ecosystem services. This review examines whether and how the dynamic nature of tidal flat - wetlands systems contributes to, or detracts from, their role in coastal defense. The focus is often on specific elements of the complex system, such as vegetation structure and cover, rather than on their complex natural dynamics. Although these processes are well described in established literature, this information is rarely applied to understanding the role of these ecosystems as coastal defense. In the continuum from unvegetated tidal flats to salt marshes and mangroves, fundamental physical controls as well as biotic interactions, and feedbacks among them, determine morphology and vegetation distribution. This ensures coastal resilience and provision of essential ecosystem services, such as wave attenuation reducing coastal flooding and erosion. Coastal managers worldwide increasingly recognize the importance of conservation and restoration of natural coastal ecosystems.
