Formation of offshore tidal sandbanks triggered by a gasmined bed subsidence [PDF]

, 2002
Offshore gasmining is an example of a human intervention with a morphological impact. On land, it is usually attended with a dish-like bed depression.

Modeling meander morphodynamics over self-formed heterogeneous floodplains [PDF]

, 2017
This work addresses the signatures embedded in the planform geometry of meandering rivers consequent to the formation of floodplain heterogeneities as the river bends migrate.

Remotely sensed mid-channel bar dynamics in downstream of the Three Gorges Dam, China [PDF]

, 2020
The downstream reach of the Three Gorges Dam (TGD) along the Yangtze River (1560 km) hosts numerous mid-channel bars (MCBs). MCBs dynamics are crucial to the river’s hydrological processes and local ecological function.

Paleogeographic numerical modeling of marginal seas for the Holocene – an exemplary study of the Baltic Sea [PDF]

Earth System Dynamics
The sustainable management of marginal seas is based on a thorough understanding of their evolutionary trends in the past. The paleogeographic evolution of marginal seas is controlled not only by global and regional driving forces (eustatic sea-level ...

Validation of Observed Bedload Transport Pathways Using Morphodynamic Modeling [PDF]

, 2016
Phenomena related to braiding, including local scour and fill, channel bar development, migration and avulsion, make numerical morphodynamic modeling of braided rivers challenging.

The Impact of Inherited Morphology on Sandbar Migration During Mild Wave Seasons

Geophysical Research Letters, 2023
Sandbars are ubiquitous morphologic features found in the nearshore environment throughout the world, yet predictive capabilities of their evolution remain limited.

The DynaDeep observatory – a unique approach to study high-energy subterranean estuaries

Frontiers in Marine Science, 2023
Subterranean estuaries are connective zones between inland aquifers and the open sea where terrestrial freshwater and circulating seawater mix and undergo major biogeochemical changes.

On the instability of a nonlocal conservation law [PDF]

, 2011
We are interested in a nonlocal conservation law which describes the morphodynamics of sand dunes sheared by a fluid flow, recently proposed by Andrew C. Fowler. We prove that constant solutions of Fowler's equation are non-linearly unstable.

Variabilidad morfométrica en crustáceos de playas arenosas de la Isla Grande de Chiloé, sur de Chile [PDF]

, 2013
Indexación: Web of Science; Scielo.The macroinfauna of exposed sandy beaches along the Chilean coast is dominated by crustaceans, which show an across-shore zonation; the talitrid amphipod Orchestoidea tuberculata as the dominant taxon in the upper ...

Quasi-two-layer morphodynamic model for bedload-dominated problems: bed slope-induced morphological diffusion [PDF]

Royal Society Open Science, 2018
We derive a two-layer depth-averaged model of sediment transport and morphological evolution for application to bedload-dominated problems. The near-bed transport region is represented by the lower (bedload) layer which has an arbitrarily constant ...
