Abstract Through a field experiment on sandy beach at Pingtan, China, we propose the first model to characterize variability of apparent von Kármán parameter in thermally and sedimentologically stratified air flows. The shows that is negatively correlated flux Richardson number as well sediment transport rate. atmospheric stability can be either from thermal stratification or sedimentological s...

In the aftermath of post-tropical cyclone Sandy, the federal government allocated approximately $4.5 billion to the US Army Corps of Engineers to construct dunes and fortify beaches against future storm surge and sea level rise. From a policy perspective, an important question is whether the benefits generated by these projects justify their costs. This paper treats the temporal and spatial var...

The uncertainties surrounding present and future sea-level rise have revived the debate around sea-level changes through the deglaciation and mid- to late Holocene, from which arises a need for high-quality reconstructions of regional sea level. Here, we explore the stratigraphy of a sandy barrier to identify the best sea-level indicators and provide a new sea-level reconstruction for the centr...

Abstract Beach erosion phenomena have become increasingly frequent and devastating with serious economic damage on tourism. A relatively recent technique of beach protection nourishment is based the creation along shoreline an unsaturated sandy zone, in which level phreatic surface lowered by means buried drains connected to electric suction pumps. The main problem encountered this solution nee...

Determining the position of range edges is the first step in developing an understanding of the ecological and evolutionary dynamics in play as species' ranges shift in response to climate change. Here, we study the leading (poleward) range edge of Ocypode cordimanus, a ghost crab that is common along the central to northern east coast of Australia. Our study establishes the poleward range edge...

The inter-annual variability of the fish and macrocrustacean spring community on an intertidal sandy beach near the Canche estuary (North of France) was studied from 2000 to 2013 based on weekly spring sampling over an 11-year period. Twenty-eight species representing 21 families were collected during the course of the study. The community was dominated by a few abundant species accounting for ...

To investigate factors related to the distribution of intertidal species, and specific predictions of the swash exclusion hypothesis for exposed sandy beaches, we compared the burrowing abilities and swash behavior of three species of anomuran crabs in the superfamily Hippoidea (Emerita analoga, Blepharipoda occidentalis and Lepidopa californica) which commonly inhabit the intertidal and shallo...

A study to monitor marine pollution with reference to trace elements (Fe, Zn, Mn and Cu) on T. attenuata, commonly called as screw shell over a period of one year on the whole body and various organs, viz. digestive diverticula, foot, mantle and ovary was conducted from the sandy beach of Porto Novo Coast (Lat 11 degrees 29' N Long: 79 degrees 46' E) of Peninsular India using Atomic Absorption ...
