Water that moves up the beach in a wave flows back out to sea due to gravity
Thats easy!

Waves do not transport matter (except fot the matter equivalent of energy, according to the Theory of Relativity). For example, in a water wave, the wave moves on, but each water particle goes back to its place.Waves do not transport matter (except fot the matter equivalent of energy, according to the Theory of Relativity).

The water particles move in a circular motion. They swing forward and then back. The water itself does not really move to the shore. If that happened, the beach you would be on would be overflowing with water. The water particles just do a little jolt along with the wave. Then, they return to their original position.
Water does not travel along with the wave. As the wave moves over the water, each little piece of water moves up and down and forward and back, but after the wave has moved on the water is in the same place. That is a common feature of wave motion. The energy is passed along the wave but the medium itself does not move with the wave.

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).

The pump that moves hot water through a hot water heater is the recirculation pump. This pump moves the water through the heater and back through the intake line.
The water cycle is what moves most of the water on Earth. The water that is on the Earth's surface evaporates and the winds moves it in the air. The water will then fall back as precipitation, such as rain or snow, onto the Earth.
They are born on the beach, and they crawl down the beach to the water.

Water moves into the air through the process of evaporation. Water moves from the air the ground by the process of raining.
Undertow causes the sand to be removed from the beach and carried back out into the water.
The earth rotates on it axis. As it rotates, Gravity from the Sun and the moon hold the water a little stronger than they do the ground. This is called the tides. This tendency to hold the water back is strongest at the equator where the earth is rotating the fastest and it is weakest at the poles. Since the earth moves eastward, the water lags and flows toward the west close to the equator. Since land gets in the way, it flows north or south when it hits land. It flows back when it gets nearer the poles where the earth is moving slower and causing less of pull on the water than toward the equator.
An undertow flows away from the shore, toward the open water.
