This review focuses on recent advances in process-based numerical models of the impact of
extreme storms on sandy coasts. Driven by larger-scale models of meteorology and …

Exceptional megaflood-scale bedforms on Earth are commonly associated with the
catastrophic draining of glacial lakes in the late Pleistocene. The widest studied events have …

In rivers, coastal seas and transitional waters, sediment transport processes involve a variety
of interacting factors that dynamically vary over time and space. The flow dynamics within …

Results from computational morphodynamics modeling of coupled flow–bed–sediment
systems are described for 10 applications as a review of recent advances in the field. Each …

Despite the inherent difficulties in quantifying its value, bedload transport is essential for
understanding fluvial systems. In this study, we assessed different indirect bedload …

The transition from the Andes to the Amazon lowland hosts a high biodiversity and currently
is facing several anthropogenic activities, including hydropower infrastructure projects. Little …

This study presents the implementation and validation of a new sediment-scour model with a
strict vertex-based, terrain conformal, moving-mesh technique within the framework of …

Rivers typically present heterogeneous bed material, but the effects of sediment
nonuniformity on river bar characteristics are still unclear. This work investigates the impact …

The Ucayali River is one of the most dynamic large rivers in the world, with high rates of
channel migration regularly producing cutoffs. In the lower portion of the Ucayali River …

The frictional influence of the seabed on the tidal flow in shelf seas and estuaries is usually
modelled via a prescribed, spatially/temporally invariant drag coefficient. In practice, the …
