Flume Experiments on Flow in Mobile Bed Channels
Journal of the Hydraulics Division, 1970There is an enormous variability in the flow equations which were proposed for mobile-bed channels, and which contain a term that purports to measure sediment load. J. W. Johnson compiled experimental data on sediment transport data that existed prior to 1948 to address this problem.

Flume Experiments on the Durability of Mud Clasts
SEPM Journal of Sedimentary Research, 1972ABSTRACT 3 cm square by 0.5 cm thick mud clasts of three different sediment samples and varying water contents were eroded in a sand-bottomed flume at velocities of 25 cm/sec and 60 cm/sec. It was found that clay-rich and initially plastic clasts resist erosion the best, but that all clasts abrade and round quickly if velocities are high enough to ...

Flume experiments on the erosion of till shores by waves
Coastal Engineering, 1994Abstract Hydraulic tests of the erosion by waves of a laboratory flume profile made from intact samples of till, a preconsolidated cohesive material, are described. Over 1000 h of testing were successfully completed using random breaking waves, varying conditions of sand cover, and varying mean water levels.

WAVE FLUME EXPERIMENT ON SEABED RECONSTRUCTION BY LIQUEFACTION
Marine Geology & Quaternary Geology, 2013In this paper,we studied the variation of the granular composition,microstructure and strength of seabed sediments under continuous wave actions and the contribution of wave-induced seabed fluidization to the physical properties of seabed sediments.The silt sediment used in the experiment was taken from the modern Yellow River delta.The experiment ...

Numerical simulation of experiments in a meandering flume
2001Numerical modelling of the flow in a meandering channel is compared with experiments done by one of the authors. A peculiar 2DH model, where bottom shear stresses are computed taking into account also accelerations, has been developed for the comparison.

Flume experiments on the mobility of landslides with erosion
Landslides are highly dynamic events in which the erosion and entrainment of basal sediment can greatly enhance landslide mobility and energy, extending travel distances and intensifying impact forces. Understanding under which erosive conditions the mobility of landslides will be enhanced or reduced, thus, is critical for improving hazard assessments.Katharina Wetterauer +5 more

Recirculation and Sand-Feed Type Flume Experiments
Journal of the Hydraulics Division, 1967Two types of open-channel laboratory flumes (recirculating and sand feed) are used to simulate the hydraulic and sediment transport phenomena which occur in natural sand-bed streams. A 20-cm wide by 10-m long flume which could be operated either as a feed system or as a recirculation system was used to compare the two systems with respect to the ...

Sidewall and non-uniformity corrections for flume experiments
Journal of Hydraulic Research, 2014ABSTRACTStudying open channel flow and sediment transport in narrow flumes under non-uniform flow conditions, both sidewall and non-uniformity corrections are required for bed-shear stress. This research first reviews conventional predictive methods for bed-shear stress, including the flow-depth method, the hydraulic radius method and Einstein's ...

Dynamics of Wood Transport in Streams: A Flume Experiment
Earth Surface Processes and Landforms, 1997The influence of woody debris on channel morphology and aquatic habitat has been recognized for many years. Unlike sediment, however, little is known about how wood moves through river systems. We examined some dynamics of wood transport in streams through a series of flume experiments and observed three distinct wood transport regimes: uncongested ...
