Morphodynamic Evolution and Sustainable Development of Coastal Systems

Journal of Marine Science and Engineering, 2022
Coastal systems are highly dynamic morphological environments due to erosion and sedimentation at different spatio-temporal scales as a result of natural forcing [...]

Modelling Coastal Morphodynamic Evolution under Human Impacts: A Review

Journal of Marine Science and Engineering, 2023
Coastal and estuarine morphogenetic evolution has been affected by anthropogenic activities. Human activities have become an important external force for the future prediction of morphological evolution in ecosystem health.

Parameter uncertainty in medium-term coastal morphodynamic modeling [PDF]

Scientific Reports
Rising sea levels and anthropogenic activities are intensifying pressure on coastal zones. Process-based coastal morphodynamic models are increasingly used to forecast natural and anthropogenic beach morphology changes at various spatio-temporal scales ...

Effect of hydro-climate variation on biofilm dynamics and its impact in intertidal environments [PDF]

Earth Surface Dynamics, 2022
Shallow tidal environments are very productive ecosystems but are sensitive to environmental changes and sea level rise. Bio-morphodynamic control of these environments is therefore a crucial consideration; however, the effect of small-scale biological ...

Hindcasting morphodynamic evolution with sand–mud interactions in the Yangtze Estuary [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
Previous work on morphodynamic evolution in the Yangtze Estuary (YE) is based on measured historical bathymetries. To evaluate the sensitivity of sand–mud interaction in the estuarine morpho-dynamics, a process-based morphodynamic model, Delft3D, is used

Emulating the estuarine morphology evolution using a deep convolutional neural network emulator based on hydrodynamic results of a numerical model

Journal of Hydroinformatics, 2022
Coastal and estuarine areas present remarkable environmental values, being key zones for the development of many human activities such as tourism, industry, fishing, and other ecosystem services.

Morphodynamic Evolution of Dredged Sandpits [PDF]

Journal of Coastal Research, 2010
Numerical modeling of dredged pits is conducted to investigate the hydrodynamic and morphodynamic interaction in offshore sand extractions. Based on an analytical formulation, a semianalytical numerical model (MEMPITS) has been developed to study the morphodynamic evolution of offshore (ho > 20 m) sand borrow areas. The numerical model has been applied

In-Stream Tidal Energy Resources in Macrotidal Non-Cohesive Sediment Environments: Effect of Morphodynamic Changes at Two Bays in the Upper Gulf of California

Journal of Marine Science and Engineering, 2021
Because of the need to diversify the renewable energy matrix and because hydrokinetic tidal energy technologies are mature, many in-stream tidal energy resource studies are available globally.

Morphodynamic evolution of double‐barred beaches [PDF]

Journal of Geophysical Research: Oceans, 2006
The linear and nonlinear morphological behavior of double‐barred coastal systems under the forcing of obliquely incident waves is studied using a nonlinear numerical model. The linearly most unstable bed forms consist of crescentic patterns (rip channels), whose spacing depends on the magnitude of the longshore current velocity.

Morphodynamic Hierarchy and the Fabric of the Sedimentary Record

Geophysical Research Letters, 2020
The low temporal completeness of fluvial strata could indicate that recorded events represent unusual and extreme conditions. However, field observations suggest that preserved strata predominantly record relatively common transport conditions—a paradox ...
