For more than four decades remote sensing images have been used to document and
understand the evolution of aeolian sand dunes. Early studies focused on mapping and …

Sand dunes are one of the most abundant aeolian landforms and play an important role in
understanding how aeolian environments evolve. Since the 1970s, remote sensing has …

It is more than half a century since the publication of RA Bagnold's classic book The physics
of blown sand and desert dunes, and it is a tribute to the quality of Bagnold's work that many …

Untitled Page 1 Page 2 GEOMORPHOLOGY OF DESERT DUNES Sand dunes cover up to a
quarter of many desert regions. Determining the factors that determine their shape, size and …

Nonrenewable energy resources, comprising fossil fuels and uranium, are not ran domly
distributed within the Earth's crust. They formed in response to a complex array of geologic …

This paper examines the stresses on coastal plants and plant adaptations imposed in the
coastal dune environment. The coastal dune ecosystem experiences severe stresses in the …

Sand dunes form an important and unique system that can be mobile or fixed by vegetation.
The common mobility indices of sand dunes, which are related to the wind and the amount …

Molecular phylogeny and biogeochemistry indicate that eukaryotes differentiated early in
Earth history. Sequence comparisons of small-subunit ribosomal RNA genes suggest a …

Many kinds of sediment bedforms are presumed to trend either normal or parallel to the
direction of sediment transport. For this reason, the trend of bedforms observed by remote …
