In the rapidly warming sub-arctic areas, it is not known how the climate emergency driven changes in hydroclimatic conditions will affect the fluvio-morphological processes like bank erosion, sediment transport and meander migration, and especially t

Macro-turbulent flows (i.e., coherent flow structures reaching through the whole water column), have not been studied widely in northern seasonally frozen rivers during both open-channel and ice-covered flow conditions. Thus, we aim: (1) to detect an
