A meandering stream migrates laterally by sediment erosion on the outside of the meander (that is part of the friction work), and deposition on the inside (helicoidal flow, deceleration, channel lag, point bar sequence, fining upwards). As the surface flow of water hits the outer bank it corkscrews, flows along the river bed then deposits eroded material on the inner bank. The water flows more slowly in the shallow areas near the inside. You can see this whole process happen in several places in the GIF at top (and in the diagram at right, by Wikipedia userMaksim).
