A Numerical Investigation on Tidally Induced Sediment Transport and Morphological Changes with Changing Sea Level in South-East England

Geosciences, 2019
The impact of tide-induced morphological changes and water level variations on the sediment transport in a tidally dominated system has been investigated using the numerical model Delft3D and South-East England as a test case. The goal of this manuscript

Flexible patchy vegetation in a meandering bend: Effect on main flow and dispersion processes

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
The presence of finite flexible and submerged vegetation patches in bends alters the typical curvature‐induced circulation motion and the streamwise velocity distribution, determining a fragmented flow patternThe lateral dispersion and the mass exchanges are strongly influenced by the vegetated patches and turbulent structures forming in patch‐adjacent

Land Reclamation Controls on Multi‐Centennial Estuarine Evolution

Earth's Future
Land reclamations influence the morphodynamic evolution of estuaries and tidal basins, because an altered planform changes tidal dynamics and associated residual sediment transport.

Introduction à l'étude écologique d'un cours d'eau. (Cf. erratum dans n° 252, p. 131)

Knowledge and Management of Aquatic Ecosystems, 1973
The standard study aims at giving the hydrobiological situation of one river at the time of the study. That situation concerns the morphodynamic, physical, chemical, phytozoological characteristics, the population of fishes and their relationships, with ...

Analysis of autogenic bifurcation processes resulting in river avulsion [PDF]

Earth Surface Dynamics
River bifurcations are constituent components of multi-thread fluvial systems, playing a crucial role in their morphodynamic evolution and the partitioning of water and sediment. Although many studies have been directed at exploring bifurcation dynamics,

Sensitivity of simulated flow fields and bathymetries in meandering channels to the choice of a morphodynamic model [PDF]

, 2016
Morphodynamic models are used by river practitioners and scientists to simulate geomorphic change in natural and artificial river channels. It has long been recognized that these models are sensitive to the choice of parameter values, and proper ...

A novel framework for analysing river planform characteristics in data‐scarce regions using remote sensing data

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Using a three‐step framework of data preprocessing, analysis and interpretation, we provide insights into the seasonal and annual pattern of morphological changes, the overall bed form and dynamics and the location of morphological uniform river sections to assess the current morphological river state in data‐scarce regions.

3D layer-integrated modelling of morphodynamic processes near river regulated structures [PDF]

, 2016
Sedimentation and erosion can significantly affect the performance of river regulated reservoirs. In the vicinity of flow control structures, the interaction between the hydrodynamics and sediment transport often induces complex morphological processes ...

Associating Local‐Scale Physical Habitat Assemblages With Reach‐Scale Stream Hydrogeomorphological Types in Mountain Headwater Catchments

River Research and Applications, Volume 42, Issue 3, Page 527-546, March 2026.
ABSTRACT Building an understanding of river ecosystems often involves integrating information from different locations, spatial scales and points in time. Geomorphologists and ecologists have long considered ways to explore river ecosystems at different, hierarchical, spatial scales so that features observed locally can be linked to the character of ...

MORPHODYNAMIC MODEL TO SIMULATE SHORELINE EVOLUTION AT ANY COASTAL MOUND

Coastal Engineering Proceedings, 2018
The work presents the results of a field and numerical study aimed to investigate the resistance and resilience, associated to an artificial shoreline perturbation, on a sandy beach. A temporary groin was deployed on a micro-tidal sea-breeze dominated beach to induce a shoreline perturbation.
