Designing Improved Sediment Transport Visualizations [PDF]

, 2013
Monitoring, or more commonly, modeling of sediment transport in the coastal environment is a critical task with relevance to coastline stability, beach erosion, tracking environmental contaminants, and safety of navigation.

Towards an anthropology of acquisition: ‘How did you get that?’ Vers une anthropologie de l'acquisition : « Où as‐tu trouvé ça ? »

Journal of the Royal Anthropological Institute, EarlyView.
The production‐distribution‐consumption triad has structured how anthropologists understand exchange for roughly a century. This article argues for expanding this triad to include an explicit focus on acquisition – the systems, processes, and practices of acquiring.

Scour near Offshore Monopiles, Jacket-Type and Caisson-Type Structures

Journal of Marine Science and Engineering
Scour near various offshore structures (monopile, caisson foundation and jacket structure) was studied by performing laboratory flume tests and numerical solutions with a semi-empirical model (SEDSCOUR) and a sophisticated 2DV model (SUSTIM2DV).

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat

Integrative Zoology, EarlyView.
After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

Impact of armour layer on the depth of scour hole around side-by-side bridge piers under ice-covered flow condition

Journal of Hydrology and Hydromechanics, 2019
In the present study, experiments were conducted in a large-scale flume to investigate the issue of local scour around side-by-side bridge piers under both ice-covered and open flow conditions.

Within-Event Spatially Distributed Bedload: Linking Fluvial Sediment Transport to Morphological Change [PDF]

, 2012
Maps of apparent bedload velocity are presented along with maps of associated channel change. Apparent bedload velocity is the bias in acoustic Doppler current profiler (aDcp) bottom track (Doppler sonar) due to near-bed particle motion (Rennie et al ...

Burrow Persistence and Spatial Distribution of Federally and State‐Protected Gopher Tortoise (Gopherus polyphemus) Populations in Southwest Alabama

Animal Conservation, EarlyView.
The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...

Erosion and deposition in interplain channels of the Maury channel system [PDF]

, 1981
Large turbidity currents originating on the insular margin of southern lceland have flowed clown a 2 500 km-long pathway comprising rise valleys, unchanneled plains and segments of erosional and depositional deep-sea channels that are collectively called

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.
