Formation of Oxbow Lakes
Rivers containing curves and twists get differently carved via the surrounding topography. Due to sedimentation and continuous erosion along the sides of the meanders, the end loop of the meander comes nearer and nearer.
Eventually, the meander spirals cut off the river, forming an oxbow lake. If only one loop gets cut off, the lake becomes crescent-shaped, whereas if more than one loop gets cut off, the lake becomes bending or winding.
