The need for construction sand needs to increase due the in population. use of dunes and coastal disfigures shorelines consequences are alarming. It is therefore necessary consider replacing these resources with other more ecological ones. Hence, it purpose this article. In paper, we study correct formulation concrete using dredged sand, respecting standards, analyze impact new material on phys...

The accurate prediction of sand transport rates in the coastal zone depends not only upon the choice of sediment transport model but also, rather critically, upon the formulation used to predict the bed roughness (ks). Sand transport rates are modelled here using both a One-equation, turbulence-closure, TKE-model and also Bijker’s sand transport model. Following some remarks about the nature an...

Clematis flammula var. maritima is a woody lianoid plant that grows on coastal sand dunes in the Mediterranean region. Older perennial stems are present as extensive underground axes. These generate surface growth of shorter-lived stems producing monospecific trellises above the surface of the sand. Despite its sand dune habitat and shortage of host support plants, this variety of Clematis show...

We tested the role of interspecific competition in driving species distribution at multiple spatial scales using two sibling species of Galerida larks (G. cristata and G. theklae) in Morocco (sympatry), Balearic islands (G. theklae only) and Israel (G. cristata only). We first investigated regional-scale determinants by contrasting allopatric versus sympatric patterns in five distinct habitat t...

Natural and Nature-Based systems provide an opportunity for adaptive response to Coastal Storm Risk Management Sea Level Rise. The Tigertail Lagoon/Sand Dollar Island Restoration on Marco Island, Florida, presents a case study designed maintain enhance existing coastal barrier system consisting of 3-km-long sand spit tidal lagoon ecosystem that is otherwise evolving toward closure. part nature-...

A new species of Scutalus Albers, 1850 (Gastropoda: Bulimulidae), Scutalus chango sp. n., is described from a coastal area of northern Chile. Empty shells of this new species were found buried in sand and under boulders and rocks in the foothills of the Chilean Coastal Range at Paposo, Región de Antofagasta. This new species is distinguished from all other Chilean terrestrial snails by its slen...

Sustainable management of highly dynamic coastal topography with fast moving sand dunes, eroding shoreline and anthropogenic changes to bathymetry and beaches represent significant challenges for coastal management. Modern mapping technologies bring capabilities to monitor this dynamic environment with unprecedented spatial and temporal detail. The general research strategy for coastal areas [1...

Coastal barrier systems have been widely used to understand the responses of coastal margins to fluctuating Pleistocene sea levels. What has become apparent, particularly with the development of robust chronological frameworks, is that gaps in terrestrial barrier sedimentary records are not uncommon and that they most likely reflect phases of barrier construction on the now submerged continenta...
