Boltzmann Distribution of Sediment Transport [PDF]
Physical Review Letters, 2019 The coupling of sediment transport with the flow that drives it allows rivers to shape their own bed. Cross-stream fluxes of sediment play a crucial, yet poorly understood, role in this process. Here, we track particles in a laboratory flume to relate their statistical behavior to the self organization of the granular bed they make up.

Effects of temperature on in vitro sediment reworking processes by a gallery biodiffusor, the polychaete Neanthes virens [PDF]
, 2004 Temperature-induced variations in bioturbation could affect sediment mixing processes in the marine benthic environment. In this study, sediment reworking by Neanthes virens (Sars), a widely distributed polychaete in muddy sand communities of northern ...

Wave simulation for the design of an innovative quay wall: the case of Vlorë Harbour [PDF]
Natural Hazards and Earth System Sciences, 2017 Sea states and environmental conditions are basic data for the design of marine structures. Hindcasted wave data have been applied here with the aim of identifying the proper design conditions for an innovative quay wall concept.

Numerical Simulation of Slope–Gully–Stream Sediment Transport Process with Water and Gravity Erosion
Frontiers in Earth Science, 2022 Soil erosion has become a global problem with serious consequences. It is the source of sediment in rivers, and the subsequent sediment transport is important.

Influence of Beach Slope on Morphological Changes and Sediment Transport under Irregular Waves
Journal of Marine Science and Engineering, 2023 This paper presents new data from large-scale wave flume experiments. It shows the beach profile evolution and sediment transport for two different bed slopes (1:15 and 1:25), and three irregular high-energy erosive wave conditions and one low-energy ...

Comparisons between sediment transport models and observations made in wave and current flows above plane beds [PDF]
, 1997 As a part of the MAST2 G8-M Coastal Morphodynamics project, the predictions of four sediment transport models have been compared with detailed laboratory data sets obtained in the bottom boundary layer beneath regular waves, asymmetrical waves, and ...

Impacts of river engineering on river channel behaviour : implications for managing downstream flood risk [PDF]
, 2020 Although knowledge of sediment transport has improved over the last 25 years, our understanding of bedload transfer and sediment delivery is still based on a limited set of observations or on models that make assumptions on hydraulic and sediment ...

Modeling the spatially distributed nature of subglacial sediment transport and erosion [PDF]
Earth Surface Dynamics, 2023 Glaciers expel sediment as they melt, in addition to ice and water. As a result, changing glacier dynamics and melt produce changes to glacier erosion and sediment discharge, which can impact the landscape surrounding retreating glaciers, as well as ...
