MORPHODYNAMIC INSTABILITIES IN THE SURF ZONE [PDF]

Coastal Engineering 2004, 2005
The bed forms in the surf zone can grow as a result of natural morphodynamic instabilities, forced by the wave-induced flow. This work gives a contribution to the dynamics of the formation and evolution the bed forms in surf zone. We use the new morphodynamic model, M-SHORECIRC, to analyze the growth and dynamics of bar-type, rhythmic, bed forms of a ...

Genipin‐Crosslinked, Silane‐Anchored 3D Tumor–Stroma Microtissues for High‐Content On‐Chip Drug Testing

Advanced Healthcare Materials, Volume 15, Issue 24, 25 June 2026.
We describe a microfluidic tumor‐stroma co‐culture model, engineered to resist collagen‐hydrogel contraction driven by fibroblast activity. Surface silanization with APTES covalently anchors the matrix to the chip, while Genipin crosslinking progressively increases stiffness and elasticity without harming cells. This supports >10 days of co‐culture and

T‐Cell Exhaustion in the Tumor Microenvironment: Subcellular Dysfunction, Pan‐Cancer Characteristics, and Therapeutic Interventions

Advanced Science, Volume 13, Issue 33, 15 June 2026.
This study elucidates the mechanisms of subcellular multidimensional collapse in exhausted T cells. By specifically targeting the nucleus, mitochondria, and endoplasmic reticulum, strategic interventions can effectively remodel the compromised organelle network. This integrated approach drives comprehensive T cell resuscitation, ultimately establishing

Morphodynamic Profiling of Protrusion Phenotypes [PDF]

Biophysical Journal, 2006
We propose a framework for tracking arbitrary complex cell boundary movements, relying on a unique definition of protrusion and retraction as the pathlength a virtual edge marker traverses when moving continuously perpendicular to the cell boundary. We introduce the level set method as a numerical scheme to reconstruct continuous boundary movement in ...

Creek‐imposed gradients reshape plant allometric traits and sediment retention in a salt marsh

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Tidal creeks impose strong hydrological and geomorphic gradients that shape plant traits and sediment dynamics in salt marshes. However, how creek‐imposed gradients reorganize plant allometric strategies and how these trait shifts regulate sediment retention remain poorly quantified.

Modeling Seasonal Variations of Sediment Transport and Morphological Changes in Delta Ecosystem: A Case Study of the Wulan Delta, Indonesia

Ilmu Kelautan
The suspended sediment from the Serang River plays a crucial role in the development of the Wulan Delta. This study employs the open-source DELFT3D model to investigate seasonal hydrodynamics, sediment distribution, and morphodynamic changes in the delta.

Low sediment retention efficiency limits delta formation in tectonically confined high‐energy coastal systems

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Conceptual framework showing how tectonic confinement, steep monsoon‐driven river dynamics, high‐energy coastal processes and offshore sediment dispersal together limit sediment retention at the Narmada–Tapi river mouths, suppressing sustained subaerial delta formation despite high sediment supply. Abstract Although deltaic growth is commonly linked to

Advances in cross-shore profile characteristics and sediment sorting dynamics of tidal flats

Shui kexue jinzhan, 2018
The cross-shore profile shape and sediment sorting of tidal flats play an important role in the research of estuarine and coastal morphodynamics, and bear practical significance for maintaining biodiversity, exploring sedimentation history, and assessing

Using Fine Sediment Monitoring to Quantify Sand Loading Over Time

River Research and Applications, Volume 42, Issue 5, Page 1099-1111, June 2026.
ABSTRACT Riverine sand loading can lead to geomorphic change, impacting river processes like lateral migration and vertical aggradation or degradation. Yet many sediment monitoring programs track only fine sediment measurable as total suspended solids (TSS). Here, we assess the ability for TSS data to be used to determine sand loading.
