The river flows and ice‐covered season plays an important role developing river channels. These earth surface processes and landforms are a new study from the University of Eastern Finland shows. The spatial variability of sediment transport and differences in depositional and erosional locations increase in ice‐covered conditions.
However, the greatest erosional forces locating in the shallow sections of the river. That’s in both open‐channel and ice‐covered conditions. Although, ice cover narrowed the flow area. The findings published in Earth Surface Processes and Landforms.
“In subarctic regions, the ice-covered flow season lasts up to eight months of the year. Most noteworthy, this is something that is taken into consideration. Especially when analysing sediment transport in rivers. Yet, this has very rarely been the case,” says Dr Eliisa Lotsari from the University of Eastern Finland.Researchers at the University of Eastern Finland and the University of Turku simulated the ice‐covered flow in a meandering subarctic river, the Pulmanki River, in northern Finland.
