When water "runs off" the land surface, that’s runoff! Due to gravity, the water you wash your car with runs down the driveway as you work, and rain runs downhill. Runoff is an important component of the water cycle.Drawn downward by gravity, the water starts to fill the empty or partially empty spaces in the soil or between rock particles. When the infiltrating water reaches the water table and the saturated zone, it starts to move horizontally with the groundwater. Groundwater in the saturated zone flows from higher to lower elevations.May 18, 2023 by Thomas. Surface water is any water that is found on the earth’s surface, such as water in a lake or river.
