  • Interactions between river flows and colonizing vegetation on a braided river: exploring spatial and temporal dynamics in riparian vegetation cover using satellite data

  • River, Italy. The study period (2004-2009) of increasing flow disturbance allows the exploration of vegetation dynamics within the river's active corridor under changing flow conditions. The analysis demonstrates the utility of ASTER data
  • for investigating vegetation dynamics along large fluvial corridors and reveals both spatial and temporal variations in the expansion, coalescence, and erosion of vegetated patches within the study reach. It is illustrated that the rate of growth of riparian trees
  • is crucial to their ability to contribute actively to river corridor dynamics.

  • Holocene loess and its deposition dynamics in the upper reaches of the Huaihe River
  • This paper aims to explore the pedogenic process, dust source, and transport dynamics of the loess-soil sequences in the upper reaches of the Huaihe River, based on comparison of the geographical setting, magnetic susceptibility, grain size between
  • of the Yellow River. The yielding and carrying dynamics of the dust in the Huaihe River is the northeast wind prevails in the winter half year.

  • This paper presents results of a numerical sensitivity experiment undertaken using computational fluid dynamics (CFD) with the purpose of understanding the flow dynamics of a series of idealized bifurcations. A geometric sensitivity analysis
  • is undertaken for a range of channel slopes (0.005 to 0.03), bifurcation angles (22° to 42°) and a restricted set of inflow conditions based upon simulating flow through meander bends with different curvature on the flow field dynamics through the bifurcation

  • demonstrate that as the beach surface dries, sand transport increases, with sediment erosion occurring at the wet/dry surface boundary, and deposition further downwind. This dynamic structure, dependent upon changing surface moisture characteristics, results
  • in the formation of a rippled sand strip and ultimately a protodune. These findings highlight dynamic mobility relationships and confirm the need to consider transient bedforms and surface moisture across a variety of scales when measuring aeolian transport
