Observation- and Modelling of Morphodynamics in Sandy Coastal Environments [PDF]

, 2012
The topic of sandy coast morphodynamics involves the mutual influences of coastal topography, local sedimentology, the driving meteorological and hydrodynamic boundary conditions, flora and fauna, and the activities of human beings: The latter as direct ...

Flower development: from morphodynamics to morphomechanics

, 2017
The shoot apical meristem (SAM) is a small population of stem cells that continuously generates organs and tissues. We will discuss here flower formation at the SAM, which involves a complex network of regulatory genes and signalling molecules.

Field Observations of Intermittent Cross‐Shore Bed Load Transport on a Low‐Energy Beach

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Low‐energy sandy beaches typically have a rippled bed, and the presence of bed forms can strongly affect net sediment transport rates under combined forcing of waves and currents. In case low‐energetic forcing is combined with coarse sediment, bed load transport is an important mechanism to understand transport processes on such beaches.

Morphodynamics of the Parana River in the light of climate change

, 2013
The work highlights the sediment dynamics that takes place at different scales along the Middle and Lower Parana River (Argentina), by means of different numerical models. The principal aim of this study is to provide a multi-disciplinary and multi-scale

Grain Size Sorting and Steady Bars Formation in Straight Channels—Part 1: Laboratory Experiments

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Surface grain size in gravel‐bed rivers is inherently heterogeneous, with marked spatial variability that remains challenging to predict, even in the presence of regular bedforms. This study investigates surface grain size variability on self‐formed alternate bars at the scale of a single bar unit, and is divided in two parts.

Grain Size Sorting and Steady Bars Formation in Straight Channels—Part 2: Linear Theory

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract This is the second of two papers aimed to investigate grain sorting patterns associated with the formation of steady alternate bars in gravel‐bed rivers. Part 1 presented the analysis of a series of tailored experiments, performed in a mobile bed laboratory flume with fixed, straight banks. The results showed that a consistent pattern of grain

Morphodynamics of tidal inlet systems

, 2009
In this review we discuss the morphodynamics of tidal inlet systems that are typical of barrier coasts formed during a period of continuous sea-level rise during the Holocene.

Linked Canyons and Fans Communicate Through a Migrating Bedrock‐Alluvial Transition

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Net‐erosional fluvial landscapes are often treated separately from net‐depositional fluvial landscapes. Yet these landscapes are often tightly linked by means of a moving‐boundary bedrock‐alluvial transition. We consider a linked canyon‐fan system in a Basin and Range province, basing our work loosely on Rainbow Canyon and Panamint Valley, USA.

A field study of morphodynamics at "North Bay Beach", Kaikoura.

, 1990
Morphodynamics, the latest approach to surf circulation dynamics and beach morphology, is used as a framework for analysis of a mixed sand and gravel beach fronting Kaikoura, east coast of the South Island, New Zealand.

Local Characteristics of Sand Wave Patterns Are Governed by Underlying Sand Bank: A Linear Stability Approach

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Tidal sand waves are dynamic bedforms, observed in shelf seas. In some cases they co‐exist with tidal sand banks, larger‐scale bed features. Sand wave characteristics then vary over the sand bank, migrating anti‐cyclonically around the bank. Yet, little is known about the processes behind sand wave formation on a sand bank characterized by a ...
