Calculations of the Critical Shear Stress for Motion of Uniform and Heterogeneous Sediments
TL;DR: In this article, an expression for the critical shear stress of noncohesive sediment is derived from the balance of forces on individual particles at the surface of a bed, where the initial motion problem for mixed grain sizes additionally depends on the relative protrusion of the grains into the flow and the particle angle of repose.
Journal ArticleDOI
Flow and Sediment Transport on a Tidal Salt Marsh Surface
TL;DR: The physical processes that control mineral sediment deposition on a mesotidal salt marsh surface on the Atlantic Coast of Virginia were characterized through a series of measurements of sediment concentration, flow velocity, turbulence, water surface elevation, marsh topography and particle size distributions of sediment deposited on the marsh surface as mentioned in this paper.
Journal ArticleDOI
Ripple geometry in wave-dominated environments
TL;DR: In this paper, the wavelength, height, and steepness of ripples formed under oscillatory flows in flume and field studies are reexamined to construct a simple and accurate method of predicting these ripple properties.
Journal ArticleDOI
A Tsunami Deposit at the Cretaceous-Tertiary Boundary in Texas
TL;DR: At sites near the Brazos River, Texas, an iridium anomaly and the paleontologic Cretaceous-Tertiary boundary directly overlie a sandstone bed in which coarse-grained sandstone with large clasts of mudstone and reworked carbonate nodules grades upward to wave ripple-laminated, very fine grained sandstones.
Journal ArticleDOI
A theoretical model for saltating grains in water
TL;DR: In this article, the equations of motion for a sediment grain near a noncohesive bed and those for the local fluid flow are combined to produce a set of differential equations that can be solved numerically to describe the trajectory of a saltating grain as a function of time.
