BOOK REVIEW | The Beach Book: Science of the Shore [PDF]
Oceanography, 2012 The Beach Book is about beaches—but also much more. An alternative title could be "The East Coast of the USA." In addition to beaches, the book covers dunes, barriers, tidal inlets and jetties, marshes, sea level, and human occupation of a stretch of ...

A simple model for the formation of vegetated dunes
, 2000 A simple model for the dynamics of dunes associated with vegetation is proposed. Using the model, formation processes of transverse dunes, parabolic dunes and elongated parabolic dunes according to two environmental factors: i)the amount of sand at the ...

Exploration, EarlyView.Conjugated microporous polymers (CMPs) have attracted more and more attention as new photocatalysts due to their unique advantages such as high performance, long stability and strong light absorption. This review summarizes the application of CMPs as a photocatalyst in recent years and introduces the catalytic mechanism.

Transverse instability of dunes
, 2011 The simplest type of dune is the transverse one, which propagates with invariant profile orthogonally to a fixed wind direction. Here we show numerically and with a linear stability analysis that transverse dunes are unstable with respect to along-axis ...

Food Chemistry International, EarlyView.ABSTRACT In this study, honey produced from Apocynum venetum L. was collected from BC (Bachu County), SY (Shaya County), and YL (Yuli County) in Xinjiang. The basic physical and chemical properties of the honey, and the contents of total phenols, total flavonoids, and amino acids were analyzed, and 16 types of polyphenols were quantified using triple ...

National Park Service nonnative plant control in the Indiana Dunes National Lakeshore [PDF]
, 2011 Invasive plants have become a growing threat to plant diversity and hydrology in the Indiana Dunes National Lakeshore. Invasive plants compete with native plants for nutrients and sunlight, and certain invasive species have been known to completely take ...

On the crescentic shape of barchan dune
, 2004 Aeolian sand dunes originate from wind flow and sand bed interactions. According to wind properties and sand availability, they can adopt different shapes, ranging from huge motion-less star dunes to small and mobile barchan dunes.

Calculation of the separation streamlines of barchans and transverse dunes
, 2006 We use FLUENT to calculate the wind profile over barchans and transverse dunes. The form of the streamlines of flow separation at the lee side of the dunes is determined for a symmetric barchan dune in three dimensions, and for the height profile of a ...
