The transport of sand and dust by wind is a potent erosional force, creates sand dunes and
ripples, and loads the atmosphere with suspended dust aerosols. This paper presents an …

Extensive evidence of landform-scale martian geomorphic changes has been acquired in
the last decade, and the number and range of examples of surface activity have increased …

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 …

Reconstruction of the palaeoenvironmental context of Martian sedimentary rocks is central to
studies of ancient Martian habitability and regional palaeoclimate history. This paper reports …

Publisher Summary This chapter examines the morphology, process-response
relationships, and internal structures of two larger-scale groups of bed features and dunes …

A simple computer-simulation algorithm for the transport of sand by wind produces forms
resembling barchan, crescentic ridge, linear, and star natural dune classes. Sand is moved …

Patterns in nature, such as meandering rivers and sand dunes, display complex behavior
seemingly at odds with their simplicity of form. Existing approaches to modeling natural …

Earth's sand seas (dune fields) experience winds that blow with different strengths and from
different directions in line with the seasons. In response, dune fields show a rich variety of …
