  • The AA. discuss the role of Large Woody Debris, LWD, in the development of montane riparian forests and present a conceptual model of this biogeomorphic process. Riparian forests are shown to be significant in the development of channel morphology
  • Biogeography ; Coastal environment ; Ecosystem ; Floodplain ; Landscape ; North Carolina ; Quaternary ; Scale ; Soil erosion ; United States of America ; Vegetation
  • theoretical perspectives on scale linkage between geomorphic and ecological (principally vegetation) processes and responses. Then, he will apply them to problems on the coastal plain of the southeastern United States.

  • with Reynolds number but they attribute this to very low velocity beneath submerged stems, and not to the state of flow. The sediment transport relations provide support for the concept of a threshold shear stress which erosion is effectively prevented
