Unified Model of Sediment Transport Threshold and Rate Across Weak and Intense Subaqueous Bedload, Windblown Sand, and Windblown Snow

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2021; 126 (4)

Nonsuspended sediment transport (NST) refers to the sediment transport regime in which the flow turbulence is unable to support the weight of transpor......

Joint Inversion for Surface Accumulation Rate and Geothermal Heat Flow From Ice-Penetrating Radar Observations at Dome A, East Antarctica. Part II: Ice Sheet State and Geophysical Analysis

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2021; 126 (5)

Dome A is the summit of the East Antarctic Ice Sheet, underlain by the rugged Gamburtsev Subglacial Mountains. The rugged basal topography produces a ......

Characterization of Wind-Blown Sand With Near-Wall Motions and Turbulence: From Grain-Scale Distributions to Sediment Transport

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2021; 126 (8)

The impact and lift-off parameters of particles play a key role in the understanding of the saltation mechanisms in aeolian environment. However, limi......

Impact of Vegetation on Lateral Exchanges in a Salt Marsh-Tidal Creek System

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2021; 126 (8)

Salt marshes are ecologically and physically essential habitats in coastal intertidal flats. In addition to providing nursery grounds for various wild......

Revealing the Importance of Capillary and Collisional Stresses on Soil Bed Erosion Induced by Debris Flows

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2021; 126 (5)

Climate change is increasing the frequency of extreme rainfall events and the snow cover to melt at high altitudes, which may exacerbate the threat po......

Incision History of the Three Gorges, Yangtze River Constrained From Inversion of River Profiles and Low-Temperature Thermochronological Data

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2021; 126 (3)

We reconstruct the incision history of bedrock rivers based on inverse modeling of the long profile of a river channel and the low-temperature thermoc......

Migration of Reversing Dunes Against the Sand Flow Path as a Singular Expression of the Speed-Up Effect

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2021; 126 (5)

We study the morphodynamics of reversing dunes on the gravel deposits of the alluvial fan of the Molcha river at the border between the Tibetan Platea......

The Influence of Surface Stress Fluctuation on Saltation Sand Transport Around Threshold

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2020; 125 (5)

Multiscale wind velocity fluctuation and complex inertial response of sand saltation to wind variations give rise to intermittent and nonuniform sand ......

A Sequentially Coupled Catchment-Scale Numerical Model for Snowmelt-Induced Soil Slope Instabilities

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2020; 125 (5)

The frequency of snowmelt-induced soil slope instabilities is increasing in some seasonally cold regions because of climate change. Reliable hazard as......

Laboratory Experiments of Bank Collapse: The Role of Bank Height and Near-Bank Water Depth

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2020; 125 (5)

We set up a laboratory experiment to reproduce flow-induced bank erosion and bank collapse and to study the role of bank height (H-b) and near-bank wa......

Experiments on the Morphodynamics of Open Channel Confluences: Implications for the Accumulation of Contaminated Sediments

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2020; 125 (9)

Contaminated sediments are common in river networks. The flow convergence and particular flow structures in confluences, such as the flow separation z......

Holocene Climate Modulates Mud Supply, Transport, and Sedimentation on the East China Sea Shelf

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2020; 125 (10)

Shelf mud is an important sink for fluvial sediment, and it is sensitive to variations in river discharge and ocean circulation, which are significant......

The Neoproterozoic "Blood Falls" in Tarim Craton and Their Possible Connection With Snowball Earth

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-EARTH SURFACE, 2019; 124 (1)

Blood Falls refers to the outflow of iron-rich brine plumes under the Taylor Glacier in Antarctica, which have distinctive blood-like red color. It wa......
