Urban River Water Level Increase Through Plastic Waste Accumulation at a Rack Structure
Frontiers in Earth Science, 2020 Plastic debris in water systems is a major challenge for our ecosystem, because it is extremely persistent in the environment. Apart from the importance of reducing the amount of plastic entering the ocean, clearing the rivers from debris is important ...

The Depositional Record, Volume 12, Issue 3, June 2026.We document meter‐scale antidune and cyclic‐step deposits in channel–lobe transition zone (CLTZ) deposits of the Upper Cretaceous Point Loma Formation in San Diego, California. These results provide new insights into sediment transport dynamics in CLTZ environments, which are critical for understanding reservoir connectivity and heterogeneity in ...

Evaluation of bed shear stress under turbid flows through measures of flow deceleration
, 2006 In previous work it has been observed that the direct application of the law-of-the-wall in flows of high concentrations of cohesive sediments, results in overestimation of the bed shear stress.

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.

, 2002 An annular laboratory flume was used to investigate the effect of mobile cockle shells on the erosion of a cohesive sediment bed. A standard clay bed was created and shells of differing sizes placed upon it.

Laser bathymetry on rough riverbed channels: State‐of‐the‐art and future prospects
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.This literature review found that topo‐bathymetric LiDAR has been successfully used to capture the structures of rough riverbeds and detect large boulders. While all of the studies that were reviewed used sensors that were operated from fixed‐wing aircraft, few studies have yet tested UAV‐borne sensors on rough riverbeds, despite the potential offered ...

GeosciencesFlash floods in ephemeral streams are rare, short and difficult to forecast and thus to monitor. During these events, bedload transport reaches very high rates and most sediment transport occurs within a limited number of hours during the course of a ...

Hydrodynamic and ecological effects of engineered logjams: Insights from field observations
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.Drone imaging, LSPIV and electrofishing data quantified restoration effects of engineered logjam at the Emme River (Switzerland). Placement and discharge shaped flow: Side jams created longer wakes, centre jams stronger mixing; and lower discharge intensified gap velocities, whereas wake length remained stable.

Hydrological Processes, Volume 40, Issue 6, June 2026.Does input soil and land‐use quality affect SWAT parameter transfer in neighbouring watersheds? Our proxy‐basin experiment in two small agricultural watersheds under crop–livestock rotations showed that capturing LULC dynamics and refining soil characterization can substantially enhance parameter transferability to ungauged neighbouring watersheds ...

LIP11D Delta flume experiments
, 1993 This note reports simulations carried out to simulate wave transformation along the flume following the initial beach profile and the wave conditions given in Roelvink(1993). Parametric spectral and wave-by-wave approaches are compared.
