"In subarctic regions, the ice-covered flow season lasts up to eight months of the year, and this is something that should be taken into consideration 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. Using hydrodynamic 2D modelling, the researchers explored spatial variation in flow characteristics and the erosion and sedimentation potential of the ice-covered flow compared to open-channel conditions. Up until now, ice-covered flow and sediment transport conditions have mainly been...
