Experimental Investigation of Flash Flood Resulting from Dam-Break on Bed Sediment Transport
Varied flows such as flooding resulting from dam break can happen due to earthquakes, seepage, bombing, overtopping, mistake in design and project performance as well as causing financial damages and human losses. Unsteady flow during flooding events has a high impact on flow field pattern, sediment motion, ecology and also, distribution of contamination in the river. In this study, the impact ...
متن کاملStochastic modeling in sediment dynamics: Exner equation for planar bed incipient bed load transport conditions
[1] Even under flow equilibrium conditions, river bed topography continuously evolves with time, producing trains of irregular bed forms. The idea has recently emerged that the variability in the bed form geometry results from some randomness in sediment flux. In this paper, we address this issue by using the Exner equation and a population exchange model derived in an earlier paper. In this mo...
متن کاملExperimental Evidence for Statistical Scaling and Intermittency in Sediment Transport Rates
Understanding bed load transport fluctuations in rivers is crucial for development of a transport theory and for choosing a sampling interval for “mean” transport rates. Field-scale studies lack sufficient resolution to statistically characterize these fluctuations, while laboratory experiments are limited in scale and hence cannot be directly compared to field cases. Here we use a natural-scal...
متن کاملCorrection to ‘‘Experimental evidence for statistical scaling and intermittency in sediment transport rates’’
[1] In the paper ‘‘Experimental evidence for statistical scaling and intermittency in sediment transport rates’’ by A. Singh et al. (Journal of Geophysical Research, 114, F01025, doi:10.1029/2007JF000963, 2009), we performed a multiscale analysis of bed load sediment transport series collected in a large-scale experimental flume at the St. Anthony Falls Laboratory at the University of Minnesota...
