[1] Abrasion by bed load is a ubiquitous and sometimes dominant erosional mechanism for fluvial incision into bedrock. Here we develop a model for bedrock abrasion by saltating bed load wherein the wear rate depends linearly on the flux of impact kinetic energy normal to the bed and on the fraction of the bed that is not armored by transient deposits of alluvium. We assume that the extent of al...

DAI, Z.-J.; LIU, J.T.; LEI, Y.-P., and ZHANG, X.-L., 2010. Patterns of sediment transport pathways on a headland bay beach—Nanwan Beach, South China: a case study. Journal of Coastal Research, 26(6), 1096–1103. West Palm Beach (Florida), ISSN 0749-0208. Embayed beaches bounded by headlands, headland bay beaches, are a common feature along the coast of southern China. The patterns of sediment tr...

The application of magnesium alloys is greatly limited because of their relatively low strength and ductility. An effective way to improve the mechanical properties of magnesium alloy is to refine the grains. As the race for better materials performance is never ending, attempts to develop viable techniques for microstructure refinement continue. Further refining of grain size requires, however...

Intertidal sediment distribution is an important factor in the understanding of estuarine ecological, morphological and pollution processes.Airborne remote sensing is identiŽ ed as a cost-eŒective tool that may be used to provide accurate synoptic maps of estuarine sediment distributions.However, prior to the collection and analysis of airborne imagery, spectral characterization of intertidal s...

Bacterial transport through cores of intact, glacial-outwash aquifer sediment was investigated with the overall goal of better understanding bacterial transport and developing a predictive capability based on the sediment characteristics. Variability was great among the cores. Normalized maximum bacterial-effluent concentrations ranged from 5.4x10(-7) to 0.36 and effluent recovery ranged from 2...

This Coastal and Hydraulic Engineering Technical Note (CHETN) summarizes the state of understanding of the influence of grain size on surf zone sediment transport and is a companion to Smith et al. (2004). This CHETN discusses details of bed-load and suspended load transport, and the classical bed-load regime is shown to encompass two distinct modes of transport. Four LST models with varying le...

A quasi-three-dimensional suspended sediment transport model was developed and generalized to include combined wave-current effects to study bottom sediment resuspension and transport in southern Lake Michigan. The results from a threedimensional circulation model and a wind wave model were used as input to the sediment transport model. Two effects of nonlinear wave-current interactions were co...

Sediment grain-size distribution (GSD) provides rich information about sedimentary sources and can potentially do the same with regard to environmental climatic changes. However, neither traditional descriptive statistics nor curving-fitting methods fully address its complexity. We selected Greater Khingan Range in northeastern China as study area used parameterized end-member analysis (EMA) of...
