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.
A barotropic flow is the same from the top of the ocean to to the bottom-the flow is said to be uniform with depth or depth-independent. In classic wind-driven ocean circulation theory, barotropic flow is the flow that is in dynamical balance with the sea surface slope.
