On the shape and migration speed of a proto‐dune |
|
| Authors: | Hiroshi Momiji Hiraku Nishimori Steven R Bishop |
| Abstract: | The shape and migration speed of a proto‐dune are mathematically discussed. The migration speed of a low dune is shown to be inversely proportional to its wind‐directional length. Proto‐dunes, whose wind‐directional lengths are about 10 m, are expected to migrate at finite speeds. Copyright © 2002 John Wiley & Sons, Ltd. |
