Research Articles

Ice‐flow structure and ice dynamic changes in the Weddell Sea sector of West Antarctica from radar‐imaged internal layering

Authors: Robert G. Bingham, David M. Rippin, Nanna B. Karlsson, Hugh F. J. Corr, Fausto Ferraccioli, Tom A. Jordan, Anne M. Le Brocq, Kathryn C. Rose, Neil Ross, Martin J. Siegert
First Published:: 3 April 2015
Vol:: 120,
Pages:: 655–670
DOI:: 10.1002/2014JF003291

Key Points

RES‐sounded internal layers in Institute/Möller Ice Streams show flow changes
Ice‐flow reconfiguration evinced in Bungenstock Ice Rise to higher tributaries
Holocene dynamic reconfiguration occurred in much of IIS/MIS as ice thinned

Open Access

Effects of tectonic deformation and sea level on river path selection: Theory and application to the Ganges‐Brahmaputra‐Meghna River Delta

Authors: Meredith D. Reitz, Jennifer L. Pickering, Steven L. Goodbred, Chris Paola, Michael S. Steckler, Leonardo Seeber, Syed H. Akhter
First Published:: 9 April 2015
Vol:: 120,
Pages:: 671–689
DOI:: 10.1002/2014JF003202

Key Points

Mass balance avulsion formulations are adapted for spatially variable subsidence
Effects on avulsion frequency and channel residence times are predicted
Comparison with avulsion data for the Ganges‐Brahmaputra Delta shows agreement

The life of a meander bend: Connecting shape and dynamics via analysis of a numerical model

Authors: Jon Schwenk, Stefano Lanzoni, Efi Foufoula‐Georgiou
First Published:: 10 April 2015
Vol:: 120,
Pages:: 690–710
DOI:: 10.1002/2014JF003252

Key Points

Automatic extraction of individual meanders from long‐term numerical models
Three dynamic metrics show how single bends grow and respond to perturbations
Cutoff meander geometry contains the signature of its formative dynamics

Regional coseismic landslide hazard assessment without historical landslide inventories: A new approach

Authors: Theodosios Kritikos, Tom R. Robinson, Tim R. H. Davies
First Published:: 13 April 2015
Vol:: 120,
Pages:: 711–729
DOI:: 10.1002/2014JF003224

Key Points

MMI, tectonics, and topography control coseismic landslide occurrence
The modeling approach incorporates fuzzy set theory in GIS
The model requires no site‐specific data inputs to perform the assessment

Active salt deformation and rapid, transient incision along the Colorado River near Moab, Utah

Authors: Andrew P. Jochems, Joel L. Pederson
First Published:: 22 April 2015
Vol:: 120,
Pages:: 730–744
DOI:: 10.1002/2014JF003169

Key Points

Colorado River terraces and tributary long profiles record salt deformation
Rapid incision supports connection between local unloading and salt deformation
Incision rate pattern marks transient signal, perhaps from river integration
