“…For sandy rivers, their theoretical analysis showed that K cr may vary between 20 and 30. This was confirmed by flume experiments and field observations [2,23,24,28,58].…”

“…Moreover, mid-channel bars are typically not symmetric with respect to the channel centerline, but they often appear as compound bars, with the water flow mainly concentrating near the banks and sometimes cutting the entire channel width through the formation of channel bifurcations (e.g., Schuurman and Kleinhans, 2015;Duró et al, 2016). In experimental modeling of wandering and braided rivers (e.g., Ashmore, 1982;Garcia Lugo et al, 2015) the tendency of the channels to "stick to the banks" is often considered to be a side effect of the physical model. However, this may not necessarily be the result of a scaling issue, nor a consequence of the low roughness of the banks, but it could be associated with a natural tendency of the flow to follow the banks when they are sufficiently straight, with the bars mainly occupying the mid-part of the channel.…”

“…Large volume of sediments transport in the lower Vistula River promotes conditions for the development of river channel mesoforms. According to Ahmari and da Silva (2011), the type of channel mesoforms in the river channel is controlled by the two dimensionless parameteres of B/h m (channel width [m] and average depth [m]) and h m /D (channel depth [m] and representative sediment grain size [m]). The hydraulic characteristics of average discharge of the lower Vistula River were calculated by Łajczak (1991) from hydrometric measurements results published in hydrological yearbooks of Poland (see: Table 1).…”

“…Representative grain size of the bedload in the studied section was obtained by the sieve analysis of the sediments samples taken from the sandbars in the river reach of km 842 -867, and it equals D = 0.5 mm (Materiał... 1954) To characterize the regime of the Vistula river channel processes, we calculated two dimensionless indexes B/h m = 120 and h m /D = 6300, which provided Figure 2 shows domains of different channel forms in natural rivers and laboratory flumes (Ahmari and Silva, 2011). The average flow discharge in the lower Vistula river creates the conditions for the formation of mesoforms located in the transition area between multiply bars and alternate bars.…”
