As the waves move over the sand, they stir it up and some of it becomes entrained in the water. As the waves retreat, they take some sand with them. The water mixes out away from the beach with other water and then when it flows back up onto the beach, it doesn't land in quite the same place that it did the first time. On average, the water is moving in one direction parallel to the beach, so the entrained sand gradually moves in that direction too - thus sand bars migrate down rivers and ocean beach sand moves up the coast (or down depending on the prevailing currents).
