NUMERICAL SOLUTIONS OF COASTAL MORPHODYNAMIC EVOLUTION FOR COMPLEX TOPOGRAPHY

Journal of Marine Science and Technology, 2010
Numerical modeling of coastal morphodynamic evolution is a powerful tool for the planning and design of coastal engineering. The coastal morphological modeling system is based on the sediment conservation law, which couples modules for waves, wave-driven currents, and sediment transport rates.

Climate‐Change Projections of Flow Distribution Across the Rhine Delta

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract We project climate‐driven changes in flow and sediment partitioning across the Rhine delta using a hybrid one‐dimensional model informed by two‐dimensional sediment‐partitioning data. Simulations spanning 150 years and 540 km show a continued shift of discharge toward the Waal branch, while the effects of historical interventions gradually ...

Field Observations and Geotechnical Modeling of Dune Face Erosion During a Storm (Narrabeen Beach, Australia)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Quantifying dune face failure during storm wave conditions is critical for improving the predictive capability of coastal erosion models. However, most high‐resolution dune erosion observations used to validate these models were obtained from reduced‐scale laboratory experiments, raising questions about their applicability to field‐scale dunes.

Influence of hydrology, sediment supply and sediment gradation on river bar morphodynamics: application to the Loire River at Bréhémont (France)

E3S Web of Conferences, 2018
Rivers inherently show heterogeneous sediment sizes and can also show a strong sediment supply variability in time because of natural episodic events or as a consequence of human activities, which alter the characteristics and dynamics of alluvial bars ...

Detecting Morphological Change From DInSAR Data in Ephemeral, Braided, Gravel Bed Rivers. Application to the Ungauged Trionto River, Italy

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Estimating morphological change in braided gravel bed rivers is important to determine the geometry of the active part of the braidplain, that is the width of the area where bed material is transported and the number of active branches during a certain time interval.

Morphological evolution of the Qingshuigou subaqueous delta of the Yellow River before and after the operation of the Xiaolangdi Reservoir (1997-2007)

Frontiers in Marine Science
The Modern Yellow River Delta has a rich history of geomorphological transformations shaped by frequent avulsions and rapid progradation. However, the delta entered a phase of altered morphodynamics following the construction of the Xiaolangdi Reservoir,

Estimating Discharge From Undular Hydraulic Jumps: Feasibility Assessment Based on Flume Experiments

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Rapids are common in steep rivers, often forming where flow transitions from supercritical (Froude number, Fr > 1) to subcritical (Fr < 1) through a hydraulic jump. When upstream Fr is supercritical but close to 1, this transition may occur as an undular hydraulic jump, exhibiting a train of stationary waves downstream of the jump toe ...
