[1] Models for the overall topographic evolution of erosional and depositional systems can be grouped into two broad classes. The first class is local models in which the sediment flux at a point is expressed as a linear or nonlinear function of local hydrogeomorphic measures (e.g., water discharge and slope). The second class is nonlocal models, where the sediment flux at a point is expressed ...

[1] The proposed Surface Water and Ocean Topography (SWOT) mission would provide measurements of water surface elevation (WSE) for characterization of storage change and discharge. River channel bathymetry is a significant source of uncertainty in estimating discharge from WSE measurements, however. In this paper, we demonstrate an ensemble-based data assimilation (DA) methodology for estimatin...

Mice with inactivated genes are increasingly used as models of human atherosclerosis. The aim of the present study was to determine whether the characteristic age-related distributions of lipid deposition seen around human arterial branches are replicated in such mice. Lesions occur downstream of branch ostia in immature human aortas, but these regions are spared in adult vessels, with lesions ...

The modeling of broad crested weirs is expected to facilitate understanding, especially the behavior flow flowing through measuring instrument. under consideration hydraulic behavior, measurement accuracy, and discharge curve. In addition, there a relationship between water level upstream downstream spillway, as well variation loss energy height. From results this study, it was found that upstr...

Laminar Newtonian flow through a 2-dimensional channel with one sinusoidal wall is studied for wavelengths comparable to, or much larger than, the channel height. In the long wave limit which is solved analytically, the pressure is in phase with the wave slope and the shear stress is in phase with the wave height. As the wavelength is reduced, the shear stress maximum moves upstream of the peak...

[1] The first extensive dataset on subaqueous bed material grain size in a large river subject to reduced sediment supply is investigated alongside bathymetry, modeled flow, and sediment flux. Results suggest that following sediment supply decline and a shift to a finer sediment supply, the gravel‐sand transition (GST) in fluvial systems extends and subsequently migrates upstream. The non‐abrup...

Hydrographic data from the Antarctic Drifter Experiment: Links to Isobaths and Ecosystems (ADELIE) project are analyzed to determine the frontal structure and transport along a section across the continental shelf and slope in the northwestern Weddell Sea. The flow is dominated by three barotropic northward flowing currents: the Antarctic Coastal Current, the Antarctic Slope Front and theWeddel...

Using multi-fractal algorithm to scientifically quantify watershed morphology is one of the hot spots geomorphology research. In this paper, based on DEM data Northwest China Basin (Daxiahe), remote sensing images Daxia River were processed. The model was used extract and analyze characteristics quantified characteristic parameters 7 sub-basins river system, discussed geomorphic significance sp...
