Eventually, the curve grows so tight that the river cuts through the meander's neck to follow a new, straighter course. Fluvial FeaturesMeandering Stream - National Park Service How do meanders contribute to the shape of the cross section of a river valley? Continual erosion and deposition narrows the neck of the meander. Meanders are a result of the interaction of water flowing through a curved channel with the underlying river bed.
