Helicoidal flow is a contributing factor to the formation of slip-off slopes and river cliffs in a meandering section of the river.he helicoidal motion of the flow aids the processes of hydraulic action and corrasion on the outside of the meander, and sweeps sediment across the floor of the meander towards the inside of the meander, forming point bar deposits.
. Helicity. Helicity is simply a measure of the amount of rotation found in a storm's updraft air. If there is significant rotation in a storm's updraft air, the storm will more than likely become a supercell and possibly spawn one or more tornadoes. In the movie below, we can see how wind with horizontal rotation can be converted into the vertical.
