Flume experiments on vegetated alternate bars [PDF]

open access: yesE3S Web of Conferences, 2018
The planform morphology of a river reach is the result of the combined actions of sediment motion (erosion, transport and deposition), hydrological regime, development and growth of vegetation.

Study on the Vibration Characteristics of Marine Riser Based on Flume Experiment and Numerical Simulation

open access: yesJournal of Marine Science and Engineering, 2023
This study investigated vortex-induced vibrations of marine risers in Ocean Thermal Energy Conversion systems. Flume experiments were conducted under two conditions: Condition 1 was with a fixed riser bottom, and Condition 2 was with a fixed bottom on a ...

The validity of floating chambers in quantifying CO2 flux from headwater streams

open access: yesJournal of Water and Climate Change, 2021
The amount of CO2 exiting headwater streams through degassing plays an important role in the global carbon cycle, yet quantification of CO2 degassing remains challenging because of the morphology of headwater streams and because of uncertainty about ...

Testing applicability of image analysis for measurements of sediment concentration in laboratory experiments [PDF]

open access: yesE3S Web of Conferences, 2023
Flume experiments are typically conducted to reveal the detailed behavior of debris flows. Direct sampling at the lower end of a flume has been used to measure sediment concentrations in flume experiments; however, direct sampling measurements under non ...

Turning the tide: comparison of tidal flow by periodic sea level fluctuation and by periodic bed tilting in scaled landscape experiments of estuaries [PDF]

open access: yesEarth Surface Dynamics, 2017
Analogue models or scale experiments of estuaries and short tidal basins are notoriously difficult to create in the laboratory because of the difficulty to obtain currents strong enough to transport sand.

Measuring Sediment Transport Capacity of Concentrated Flow with Erosion Feeding Method

open access: yesLand, 2023
Sediment transport capacity in rills is an important parameter for erosion modeling on hillslopes. It is difficult to measure, especially at gentle slopes with limited rill length. In this study, a special flume with variable slope gradients in upper and

Evaluating a Laboratory Flume Microbiome as a Window Into Natural Riverbed Biogeochemistry

open access: yesFrontiers in Water, 2021
Riverbeds are hotspots for microbially-mediated reactions that exhibit pronounced variability in space and time. It is challenging to resolve biogeochemical mechanisms in natural riverbeds, as uncontrolled settings complicate data collection and ...
