Study of the use of dredged sand as an alternative to beach sand and coastal dunes for coastal preservation

, 2022
Abstract The need for construction sand needs to increase due to the increase in population. The use of dunes and coastal sand disfigures shorelines and the consequences are alarming. It is therefore necessary to consider replacing these resources with other more ecological ones. Hence the purpose of this article.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

Boreas, EarlyView.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...

Numerical Simulation of the 2004 Indian Ocean Tsunami: Case Study of Effect of Sand Dunes on the Spatial Distribution of Inundation in Hambantota, Sri Lanka

Journal of Applied Fluid Mechanics, 2010
The megathrust earthquake of moment magnitude 9.1 – 9.3 on December 26, 2004 unleashed a massive tsunami which devastated the coastal belts of Sri Lanka as well as several other countries bordering the Indian Ocean. Extensive field observations carried

Single‐grain K‐feldspar luminescence dating on primary and re‐deposited aeolian sediments in Mongolia

Boreas, EarlyView.
Owing to its location in the semi‐arid region of northern Central Asia, Mongolia is highly sensitive to climate change and therefore provides an excellent setting for palaeoenvironmental research. Proxy data from different sediment types are crucial for interpreting past climate changes and landscape evolution, while burial ages provide chronological ...

1170. Allium kollmannianum Brullo, Pavone & Salmeri

Curtis's Botanical Magazine, EarlyView.
Summary Allium kollmannianum is a small, late‐spring to early‐summer blooming Allium, endemic to the Negev Desert in south Israel, and previously thought to be extremely rare and critically endangered. Here we expand new information regarding its distribution and habitat in the Negev Desert, and a new estimation of its threat level, considering the new

Mapping wild bee diversity and flower use for an effective conservation of the Doñana biodiversity hotspot

Insect Conservation and Diversity, EarlyView.
We compiled the first checklist of wild bees in Doñana Protected Area, documenting 385 species, including three vulnerable and one endangered species listed in the Red List. Bee species exhibit diverse floral preferences, highlighting the need to incorporate plant–pollinator interactions and the role of plants in conservation and management strategies ...
