A sandbar is a shallow area in a body of water caused by a ridge of sand and other sediment. Sandbars can rise above the surface of the water, creating beaches. Since sandbars commonly occur close to land, sailing beyond sandbars signifies sailing into deeper waters. ...
This signifies that gravitational forces exert a predominant influence over inertial forces, with fluid motion resistance primarily attributed to riverbed friction [40,41,42]. Despite the significant increase in flow volume during the flood season, flow velocities are constrained by riverbed friction, ...
