Sediment transport in alluvial channels has a long history of intensive research. River ice could affect sediment and channel morphology through the impact various dynamic thermal processes. However, studies on under influence have been minimal until recent years. This phenomenon was partially due to complicated interactions between ice, flow, dynamics, which require good understanding river process, addition difficult field data collection conditions. paper reviews progress needs ice-related research morphology, including cover surface runs transport, effects frazil anchor bank stability with freeze-thaw effects.

The spatiotemporal distribution of river bank erosion events and their drivers in seasonally frozen regions

Geomorphology, Journal Year: 2024, Volume and Issue: 454, P. 109140 - 109140

River bank erosion supplies sediments to river systems, sustaining many functions. To properly understand and ultimately model erosion, we have know the temporal spatial distributions at which it occurs. This is especially challenging in cold-climate regions where a large variety of processes occur that contribute erosion. We therefore obtained one-year dataset, using buried soil sensors, on its forcing parameters with high resolution answer question: what are cold climate conditions causing these distributions? measured movements multiple sites throughout Finland compared movement times moisture, air temperature discharge information. analysis showed there no clear distribution Southernmost investigated site, while more Northern field was most frequent around freezing thawing periods. At one site an additional period increased frequency events likely caused by reindeer during summer months. research used new type dataset temperature, moisture movement. unique allowed us identify individual helps better extension fluvial systems cold-climates.
