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
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
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
Geomorphic constraints on fault throw rates and linkage times: Examples from the Northern Gulf of Evia, Greece
Journal of Geophysical Research F: Earth Surface - Tập 120 Số 1 - Trang 137-158 - 2015
Alexander C. Whittaker, A. S. D. Walker
Critical Zone Structure Under a Granite Ridge Inferred From Drilling and Three‐Dimensional Seismic Refraction Data
Journal of Geophysical Research F: Earth Surface - Tập 123 Số 6 - Trang 1317-1343 - 2018
Brady Flinchum, W. Steven Holbrook, Daniella Rempe, Seulgi Moon, C. S. Riebe, Bradley J. Carr, J. L. Hayes, James St. Clair, Marc Philipp Peters
AbstractObserving the critical zone (CZ) below the top few meters of readily excavated soil is challenging yet crucial to understanding Earth surface processes. Near‐surface geophysical methods can overcome this challenge by imaging the CZ in three dimensions (3‐D) over hundreds of meters, thus revealing lateral heterogeneity in subsurface properties across scales ...... hiện toàn bộ
Effects of Bed Forms and Large Protruding Grains on Near‐Bed Flow Hydraulics in Low Relative Submergence Conditions
Journal of Geophysical Research F: Earth Surface - Tập 122 Số 10 - Trang 1845-1866 - 2017
Angel Monsalve, Elowyn M. Yager, M. W. Schmeeckle
AbstractIn mountain rivers, bed forms, large relatively immobile grains, and bed texture and topographic variability can significantly alter local and reach‐averaged flow characteristics. The low relative submergence of large immobile grains causes highly three‐dimensional flow fields that may not be represented by traditional shear stress, flow velocity, and turbu...... hiện toàn bộ
Sediment availability on burned hillslopes
Journal of Geophysical Research F: Earth Surface - Tập 118 Số 4 - Trang 2451-2467 - 2013
Petter Nyman, Gary Sheridan, John A. Moody, Hugh G. Smith, Philip J. Noske, Patrick Lane
Constraining the relative importance of raindrop‐ and flow‐driven sediment transport mechanisms in postwildfire environments and implications for recovery time scales
Journal of Geophysical Research F: Earth Surface - Tập 121 Số 11 - Trang 2211-2237 - 2016
Luke A. McGuire, Jason W. Kean, Dennis M. Staley, Francis K. Rengers, Thad Wasklewicz
AbstractMountain watersheds recently burned by wildfire often experience greater amounts of runoff and increased rates of sediment transport relative to similar unburned areas. Given the sedimentation and debris flow threats caused by increases in erosion, more work is needed to better understand the physical mechanisms responsible for the observed increase in sedi...... hiện toàn bộ
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
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
