Elevation-related variations of soil disintegration and its driving forces in the water level fluctuation zone of the Three Gorges Reservoir, China Geomorphology (IF 3.9) Pub Date : 2024-04-11 Jiaorong Lv, Yuhai Bao, Ling Yang, Xiubin He, Haozhe Zhang, Hong Li
Soil disintegration is a key process of the early stages of soil erosion. The water level fluctuation zone (WLFZ) in reservoirs undergoes seasonal changes involving periodic alternations in inundation and exposure that can affect soil disintegration. In this study, we conducted experiments on pre-wetted undisturbed soil samples obtained from different elevations ranging from 155 to 180 m a.s.l. and

Readjustment of fluvial systems to Quaternary tectonic disruption in the Central Afar (Ethiopia) Geomorphology (IF 3.9) Pub Date : 2024-04-10 Sean G. Polun, David Horrell, Samson Tesfaye, Francisco Gomez
The Afar region constitutes the diffuse triple junction adjoining the Red Sea, Gulf of Aden, and Main Ethiopian Rifts. Extension in the Afar is distributed between on-axis, magmatic crustal spreading, and off-axis, amagmatic extension, such as in Dobe graben. The timing of initiation and development of these amagmatic grabens is key to understanding the final stages of continental extension/breakup

Geomorphological signature of topographically controlled ice flow-switching at a glacier margin: Breiðamerkurjökull (Iceland) as a modern analogue for palaeo-ice sheets Geomorphology (IF 3.9) Pub Date : 2024-04-03 Amy Lally, Alastair Ruffell, Andrew M.W. Newton, Brice R. Rea, Matteo Spagnolo, Robert D. Storrar, Thorsten Kahlert, Conor Graham
Ice low-switching, which can involve changes in ice flow velocity and direction, is crucial to a full understanding of ice masses and their response to climate change. A topographically controlled ice flow switch near a glacier margin was recently documented at Breiðamerkurjökull, southeast Iceland, where the central flow unit migrated eastward in response to variations in subglacial topography and

Investigation of the use of topographic data derived from Pléiades imagery for high-resolution hillslope-scale morphometry Geomorphology (IF 3.9) Pub Date : 2024-03-24 Victor Pellegrino, Vincent Godard, Jules Fleury
Obtaining accurate representations of the Earth surface topography is paramount in many geomorphological investigations. While regional scale studies use Digital Elevation Models (DEM) with resolution of the order of 10–100 m, in many applications resolution 5 m are mandatory to appropriately represent landforms and processes of interest. In particular, hillslopes, which cover the most of continental

Subduction erosion, commonly occurring in convergent margins, serves as a key mechanism for effective recycling of materials into the deep subduction. Subduction of bathymetric highs is widely recognized as a critical factor of subduction erosion of the forearc. The Mariana margin is an often-cited example of a tectonically erosive zone, with numerous topographic features such as seamounts, ridges

Submarine canyons are primary conduits for turbidity currents transporting terrestrial sediments, nutrients, pollutants and organic carbon to the deep sea. The concavity in the longitudinal profile of these canyons (i.e. the downstream flattening rate along the profiles) influences the transport processes and results in variations in turbidite thickness, impacting the transfer and burial of particles

Rock weathering: The effects of varying rock moisture on controlled weathering cycles in low porosity limestone Geomorphology (IF 3.9) Pub Date : 2024-03-15 Andrew Mitchell, Oliver Sass
Examples of rockwall weathering processes include diurnal heating and cooling, diurnal and seasonal freezing, wetting and drying and thawing/seasonal active-layer thawing. These stress-loading processes often occur synergistically and cause a weakening of the rockwall through the propagation of sub-critical cracks. The Acoustic Emissions (AE) released by these cracking events can be measured in order

Mobilization rates of landslides in a changing tropical environment: 60-year record over a large region of the East African Rift Geomorphology (IF 3.9) Pub Date : 2024-03-14 Arthur Depicker, Gerard Govers, Liesbet Jacobs, Matthias Vanmaercke, Judith Uwihirwe, Benjamin Campforts, Désiré Kubwimana, Jean-Claude Maki Mateso, Toussaint Mugaruka Bibentyo, Louis Nahimana, Benoît Smets, Olivier Dewitte
The impact of humans on Earth surface processes strongly increased since the offset of the 20th century, often surpassing the importance of natural drivers. In most mountainous regions, landslide mobilization rates may have increased due to human disturbances of the landscape such as deforestation, mining, and road construction. However, assessing the impact of these human disturbances is not straightforward

Hillslopes constitute the majority of a drainage basin space, and they, together with channelized streams and mountain glaciations, form the most representative exogenic agents sculpting the diverse landforms of the Earth's surface. It is well acknowledged that the hillslope evolution is dominated by a diffusion mechanism. A prominent progress in the last two decades is the proposed non-linearity in

Impact of large wood on sediment (dis)connectivity in a meandering river Geomorphology (IF 3.9) Pub Date : 2024-03-13 Tomáš Galia, Zuzana Poledniková, Václav Škarpich
Large wood (LW) can exert strong influence on sediment storage patterns in fluvial systems. However its specific impact on sediment routing is largely dependent on the stability of individual LW pieces or LW jams. We used sediment (dis)connectivity principles to quantify the impact of LW on sediment erosion and storage along a meandering river reach. Decadal spatiotemporal changes of LW and fluvial

A review of large wood dynamics relevant to hazard characteristics for built structures Geomorphology (IF 3.9) Pub Date : 2024-03-13 Gaogao Fei, Xiekang Wang
Large wood exerts an influence on the topography and geomorphology of channels in areas of good vegetation development, and it is also an important component of riverine ecosystems. However, large wood may impact and damage buildings. The formation and failure of logjams can cause backwater rise, local scour, and the amplification of flow discharge, leading to more serious disasters. Therefore, quantifying

Land-surface quantitative analysis based on digital elevation model (DEM) has been applied for improving the geomorphological mapping of piedmont alluvial fans. Indeed, these fans are frequently along a mountain front, where a series of coalescing fans may eventually occur. The margins of adjacent fans are rather difficult to map, thus preventing accurate and meaningful quantification of fan morphometric

The spatiotemporal distribution of river bank erosion events and their drivers in seasonally frozen regions Geomorphology (IF 3.9) Pub Date : 2024-03-11 Erik van Rooijen, Eliisa Lotsari
River bank erosion supplies sediments to river systems, sustaining many river functions. To properly understand and ultimately model river bank erosion, we have to know the temporal and spatial distributions at which it occurs. This is especially challenging in cold-climate regions where a large variety of processes occur that contribute to river bank erosion. We therefore obtained a one-year dataset

Rock avalanche-induced air blasts are widespread, damaging, and deadly. They can add to the destructive potential of avalanches far beyond the avalanche zone, but no landslide risk assessment in practice to date has accounted for the potential air blast danger. Here, field investigations and numerical studies were employed to quantitively analyze the initiation and propagation mechanism of air blasts
