A vector-based method for bank-material tracking in coupled models of meandering and landscape evolution
A vector-based method bank-material tracking coupled models of meandering landscape evolution
2014/4/8
Sinuous channels commonly migrate laterally and interact with banks of different strengths—an interplay that links geomorphology and life and shapes diverse landscapes from the seafloor to planetary s...
To explain the formation of meanders, the author has synthesized relevant
knowledge and utilized basic physical principles of flowing turbulent
water and its interaction with the river bed.

2009/10/13
On the basis of a field survey on bottom topography changes in the meandering river Allan Water at the cutoff (lateral overflow) section, a detailed study of velocities and boundary shear stresses in ...
Transient Gulf Stream Meandering. Part II：Analysis via a Quasi-Geostrophic Time-Dependent Model
Transient Gulf Stream Meandering Quasi-Geostrophic Time-Dependent Model
2009/3/26
Simultaneous path and bottom velocity measurements made during the Transient Meander Experiment, reported in Part I, are analyzed in terms of a quasi-geostrophic thin jet model of the meandering Gulf ...
Transient Gulf Stream Meandering. Part I: An Observational Experiment
Transient Gulf Stream Meandering Observational Experiment
2009/3/26
The results from an observational experiment on the mesoscale space-time variability of the Gulf Stream are reported. Various techniques, including aerial surveys, ship trackings of the 15C isotherm a...
The Turning Process in Meandering Currents：A Case Study
Turning Process Meandering Currents
2009/3/24
As a meandering current changes its curvature vorticity, the lateral shear, the shearing deformation, the vertical shear, and the lateral temperature gradient also change. Changes in these parameters,...
Measurements of Gulf Stream Meandering and Evidence of Seasonal Thermocline Development Using Long-Range Acoustic Transmissions
Gulf Stream Meandering Seasonal Thermocline Development Long-Range Acoustic Transmissions
2009/2/6
Phase-coded signals with 60 rms resolution were transmitted twice weekly for several months from acoustic sources at 2000 m depth in the Sargasso Sea to three bottom-mounted receives designed as West,...
A thin-jet model predicts the location of the axis of a strong current such as the Gulf Stream by using the vertical and cross-stream integrated vorticity balance, under the assumption that the meande...
Meandering and Transport Variations of the Florida Current
Subtropical Atlantic Climate Studies Transport Variations Florida Current
2009/1/8
Current meter observations were collected from a three-dimensional array moored in the Florida Straits between December 1983 and June 1984 as part of the Subtropical Atlantic Climate Studies (STACS) p...
Meandering and Eddy Detachment According to a Simple（Looking）Path Equation
Eddy Detachment Simple（Looking）Path Equation Nonlinear meandering
2009/1/6
Nonlinear meandering and “pinching off” process are investigated by solving the path equation As shown by Pratt and Stern, this dimensioned equation determines the center line latitude l of a slowly-v...
Estimating the Surface Transport of Meandering Oceanic Jet Streams from Satellite Altimetry：Surface Transport Estimates for the Gulf Stream and Kuroshio Extension
Surface Transport Estimates Kuroshio Extension Gulf Stream Oceanic Jet Streams
2008/12/27
A method has been developed to detect the location, width maximum velocity, and suffice transport of a meandering oceanic jet stream from satellite altimetry. Ale method is based on a nonlinear least ...
Fluid Exchange across a Meandering Jet Quasiperiodic Variability
Fluid Exchange meandering jet developed two-dimensional kinematic model
2008/12/10
In this paper, the motion of fluid parcels in the two-dimensional kinematic model of a meandering jet developed by Bower and Samelson is studied. The earlier work is extended by considering quasiperio...

mean Lagrangian transport Water Mass Exchange Annually Migrating Wind
2008/12/3
A simple barotropic double gyre–jet ocean circulation model is developed, driven by surface wind. The model consists of a subtropical gyre in the south and a subpolar gyre in the north and a meanderin...
