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.

Enhancements in reservoir flood risk mapping: example application for Ulley
, 2014 In July 2007, at Ulley Reservoir, South Yorkshire, a catastrophic dam failure was narrowly avoided due to emergency preventative actions. During the event, a number of homes were evacuated and roads were closed for precautionary measures.

An Overlooked Habitat‐Dependent Link Between Metabolism and Water Loss in Reptiles
Integrative Zoology, EarlyView.We measured the gas exchange of six lizard and six snake species, under high and low air humidity, and two intriguing patterns emerged. First, although desert species lose less water via evaporation than similar‐sized mesic species under similar conditions, water loss is virtually the same when each is exposed to its natural conditions.

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 ...

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

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 ...

Barrier island erosion and overwash study -- effect of seawalls. Volume 2 [PDF]
, 1992 This is the second of a pair of reports documenting the effects of storms on beach systems including the presence of seawalls. With the aim of simulating the effects of overwash on barrier islands with seawalls and characterizing their response, a ...

Early Holocene jökulhlaup chronology and deglaciation dynamics in central Iceland
Boreas, EarlyView.Glacial lake outburst floods (jökulhlaups) have occurred throughout the Quaternary in glaciated regions worldwide. Reconstructing flood chronology yields insight into deglaciation processes, environmental change and the role of extreme events in landscape evolution.

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 ...
