In Central Yakutia, frozen river banks are affected by a combination of thermal and mechanical erosion. Exceptional bank retreat of up to 40 m per year is observed. This results from ground thawing produced by heat transfer from the flow of water through the frozen ground, followed by mechanical transport of the thawed sediments. A one‐dimensional model is proposed to estimate the thermal erosion efficiency. A test of this model is a comparison of results obtained from experiments carried out in… 

Fluvial thermal erosion: heat balance integral method

In periglacial regions, frozen river banks are affected by thermal and mechanical erosion. In Siberia, bank retreats of up to 40 m per year are observed. This thermal erosion occurs during a few

Assessing the role of thermal erosion in channel deformation processes in rivers of permafrost zone

The study is focused on the deformations caused by the impact of water flow in a river channel composed of melt-able permafrost rocks. It is based on the results of laboratory and mathematical

Impact of the global warming on the fluvial thermal erosion over the Lena River in Central Siberia

The hydrology of the Lena and its tributaries is characterized by an extremely episodic flow regime. Here we report recent climatic change in Central Siberia, and its impact on the fluvial thermal

An Assessment of the Erosion Potential of the Fluvial Thermal Process during Ice Breakups of the Lena River (Siberia)

Fluvial thermal erosion following ice breakups of the Lena River (Yakutia, Siberia) is a significant geomorphic process. During the initial stage of ice breakup, ice pushes up onto the river banks

Satellite image analysis and frozen cylinder experiments on thermal erosion of periglacial fluvial islands

Frozen islands in the Lena River, Siberia, experience rates of fluvial thermal erosion exceeding 10m/year. The islands erode differentially, with rates of frontal retreat exceeding those on island

Effects of Ice Content on the Thermal Erosion of Permafrost: Implications for Coastal and Fluvial Erosion

The effects of ice content and water flow on thawing and erosion of non‐cohesive permafrost banks were investigated through laboratory experiments. A critical ice content was identified as associated

Retrogressive Thaw Slumps on Ice‐Rich Permafrost Under Degradation: Results From a Large‐Scale Laboratory Simulation

In the ice‐rich permafrost of the Arctic regions, thermokarst erosion on slopes induces the formation of large‐scale retrogressive thaw slumps (RTS). They have significant geomorphological,

Laboratory and Numerical Simulation of the Evolution of a River's Talik

Experiments simulating the evolution of a river talik were performed in a cold room where a small channel carried flowing water through frozen saturated porous soil in a hydraulic flume. The




Abstract : Experiments to study the melting of a horizontal ice sheet with a flow of water above it were conducted in a 35 m long refrigerated flume with a cross section of 1.2x1.2 m. Water depth,


Anabranching rivers consist of multiple channels separated by vegetated semi-permanent alluvial islands excised from existing floodplain or formed by within-channel or deltaic accretion. These rivers

Les systèmes fluviaux à chenaux anastomosés en milieu périglaciaire : la Léna et ses principaux affluents (Sibérie centrale)

This study deals with Siberian rivers dominated by outburst flood within a continuous and deep permafrost zone. The Lena basin rivers (Lena, Aldan and Vilioui) present specific fluvial forms: they

Anastomosis and the continuum of channel pattern

Anastomosing rivers are characterized by multiple channels separated by islands excised from the floodplain. Their status relative to the continuum concept of channel pattern is assessed with channel
