Repeated surveys reveal nontectonic exposure of supposedly active normal faults in the central Apennines, Italy
Journal of Geophysical Research F: Earth Surface - Tập 122 Số 1 - Trang 114-129 - 2017
Vanja Kastelic, Pierfrancesco Burrato, Michele M. C. Carafa, Roberto Basili
AbstractWe investigate the geomorphic processes that expose bedrock fault surfaces from under their slope‐deposit cover in the central Apennines (Italy). These bedrock fault surfaces are generally located at various heights on mountain fronts above the local base level of glacio‐fluvial valleys and intermountain fluvio‐lacustrine basins and are laterally confined t...... hiện toàn bộ
A generalized equilibrium model for predicting daily to interannual shoreline response
Journal of Geophysical Research F: Earth Surface - Tập 119 Số 9 - Trang 1936-1958 - 2014
Kristen D. Splinter, Ian L. Turner, Mark Davidson, Patrick L. Barnard, Bruno Castelle, Joan Oltman‐Shay
AbstractCoastal zone management requires the ability to predict coastline response to storms and longer‐term seasonal to interannual variability in regional wave climate. Shoreline models typically rely on extensive historical observations to derive site‐specific calibration. To circumvent the challenge that suitable data sets are rarely available, this contributio...... hiện toàn bộ
Acoustic and Microseismic Characterization in Steep Bedrock Permafrost on Matterhorn (CH)
Journal of Geophysical Research F: Earth Surface - Tập 123 Số 6 - Trang 1363-1385 - 2018
Samuel Weber, Jérôme Faillettaz, Matthias Meyer, Jan Beutel, Andreas Vieli
Understanding of processes and factors influencing slope stability is essential for assessing the stability of potentially hazardous slopes. Passive monitoring of acoustic emissions and microseismology provides subsurface information on fracturing (timing and identification of the mechanism) and therefore complement surface displacement data. This study investigates for the first time acou...... hiện toàn bộ
Numerical simulation of bar and island morphodynamics in anabranching megarivers

Post‐LGM Grounding‐Line Positions of the Bindschadler Paleo Ice Stream in the Ross Sea Embayment, Antarctica
Journal of Geophysical Research F: Earth Surface - Tập 122 Số 10 - Trang 1827-1844 - 2017
Philip J. Bart, John B. Anderson, F. O. Nitsche
AbstractThe West Antarctic Ice Sheet (WAIS) retreated more than 1,000 km since last grounding at the Ross Sea outer continental shelf. Here we show an interpretation of former grounding line positions from a new large‐area multibeam survey and a regional grid of chirp cross‐sectional data from the Whales Deep Basin in eastern Ross Sea. The basin is a paleo‐glacial ...... hiện toàn bộ
Understanding controls on rapid ice‐stream retreat during the last deglaciation of Marguerite Bay, Antarctica, using a numerical model
Journal of Geophysical Research F: Earth Surface - Tập 119 Số 2 - Trang 247-263 - 2014
Stewart S. R. Jamieson, Andreas Vieli, Colm Ó Cofaigh, Chris R. Stokes, Stephen J. Livingstone, Claus‐Dieter Hillenbrand
AbstractUsing a one‐dimensional numerical model of ice‐stream flow with robust grounding‐line dynamics, we explore controls on paleo‐ice‐stream retreat in Marguerite Bay, Antarctica, during the last deglaciation. Landforms on the continental shelf constrain the numerical model and suggest that retreat was rapid but punctuated by a series of slowdowns. We investigat...... hiện toàn bộ
Thawing of massive ground ice in mega slumps drives increases in stream sediment and solute flux across a range of watershed scales
Journal of Geophysical Research F: Earth Surface - Tập 118 Số 2 - Trang 681-692 - 2013
Steven V. Kokelj, Denis Lacelle, Trevor C. Lantz, Jon Tunnicliffe, Laura Malone, Ian D. Clark, K. S. Chin
AbstractIce‐cored permafrost landscapes are highly sensitive to disturbance and have the potential to undergo dramatic geomorphic transformations in response to climate change. The acceleration of thermokarst activity in the lower Mackenzie and Peel River watersheds of northwestern Canada has led to the development of large permafrost thaw slumps and caused major i...... hiện toàn bộ
Flow patterns and morphology of a prograding river delta
Journal of Geophysical Research F: Earth Surface - Tập 121 Số 2 - Trang 372-391 - 2016
John Shaw, David Mohrig, Wayne Wagner
AbstractThe transition of flow between laterally confined channels and the unchannelized delta front controls the morphodynamic evolution of river deltas but has rarely been measured at the field scale. We quantify flow patterns and bathymetry that define the evolution of the subaqueous delta front on the Wax Lake Delta, a rapidly prograding delta in coastal Louisi...... hiện toàn bộ
Decadal‐Scale Riverbed Deformation and Sand Budget of the Last 500 km of the Mississippi River: Insights Into Natural and River Engineering Effects on a Large Alluvial River
Journal of Geophysical Research F: Earth Surface - Tập 123 Số 5 - Trang 874-890 - 2018
Bo Wang, Y. Jun Xu
AbstractAlluvial rivers are shaped by interactions of flow and sediment transport. Their lower reaches to the world's oceans are highly dynamic, often presenting engineering and management challenges. Here we analyzed over 6,000 single‐beam cross‐sectional measurements surveyed in 1992, 2004, and 2013 in the last 500‐km reach of the highly engineered Mississippi Ri...... hiện toàn bộ
