Flume experiments on the production of stratification and cross-stratification

Journal of Sedimentary Research, 1956
ABSTRACT Experiments are being conducted in flumes designed to simulate conditions of deposition (1) through stream current action, and (2) by slumping into a standing body of water. Previous experiments, made in a wind tunnel with dry sand, formed deposits (1) by wind currents and (2) by avalanching down steep slopes.

Flume Experiments on Alternate Bar Formation

Journal of the Waterways, Harbors and Coastal Engineering Division, 1971
A series of laboratory experiments were performed to determine relationships between alternate bar geometry, bed material properties and hydraulic parameters. The experiments were conducted in a recirculating laboratory flume 100 ft long and 3 ft wide. The flume had smooth rigid walls and a movable bed. Sand, expanded clay aggregate and plastic pellets

Shoreline Autoretreat Substantiated in Flume Experiments

Journal of Sedimentary Research, 2001
ABSTRACT Under conditions of constant sediment supply (S) to the basin and a steady rate of rise (A) in relative sea level, the autoretreat theory predicts that shorelines can retreat landwards at a relatively early stage of delta growth and attain an "autobreak" state, after which the existing subaqueous slope begins to be starved of sediment and ...

Flume experiments on alternate bars in unsteady flow

1991
— Flume experiments are performed to investigate the process of development of alternate bars under unsteady flow conditions. The bed response to unsteady flow is analyzed for different values of the period of the flood and the observed temporal behaviour of the amplitude of bars, which appears to be strongly affected by the unsteady character of the ...

DUNE EROSION AND OVERWASH IN LARGE-SCALE FLUME EXPERIMENTS

The Proceedings of the Coastal Sediments 2011, 2011
The present paper gives a general overview of the large-scale physical model experiments performed at the LIM/UPC in Barcelona, within the EU-Hydralab III Integrated Infrastructure Initiative. The model tests have been carried out in a flume with a sandy dune exposed to a combination of water levels and wave conditions.

Transport of silver nanoparticles by runoff and erosion – A flume experiment

Science of The Total Environment, 2017
Silver nanoparticles (AgNPs) are being used in many products as they have unique antimicrobial-biocidal properties. After disposal of these products AgNPs can reach the soil environment possibly affecting soil organisms and disrupting plants. This work aimed to study the transport of AgNPs by water and sediment during overland flow and soil erosion ...

Flume experiments on the origin of flaser bedding

Sedimentology, 1981
ABSTRACTA series of flume runs using a 12·5 h tidal cycle was conducted in order to determine whether or not flaser beds could be formed in nearshore subtidal areas as a result of purely tidal activity. The effects of clay composition, sand size, bed thickness, and maximum current velocity were investigated.

SOME FLUME EXPERIMENTS WITH A FINE SILT

Sedimentology, 1966
SUMMARYFour flume experiments have been performed in which the behaviour was investigated of a bed of fine silt under running water with and without an excess of material introduced into suspension.In the presence of excess material, bed features were formed in the tangential stress range 0.1 < θ < 0.4, and the bed was found to remain plane in ...

Clearwater Local Scour Experiments in a Large Flume

Building Partnerships, 2000
Local sediment scour experiments have been conducted with 0.114 m, 0.305 m and 0.914 m diameter circular piles in a 6.1 m (20 ft) wide by 6.4 m (21 ft) deep by 38.4 m (126 ft) long flume in the Hydraulics Laboratory at the USGS Conte Laboratory in Turners Falls, MA. All of the tests to date have been in the clearwater scour range of velocities and with
