Groundwater flow.
Underground water is called underground water, because it is "underground" not because it is fresh or salt. You can have underground salt water reservoirs just like you can have fresh water ones.
Groundwater flow.
Percolation affects the movement underground because, when the water is passing through it dissolves all salt and minerals.
Capillary action forces water upward. So it takes the water from underground causing it to affect the movement of water under ground
Water moves underground through a process called infiltration, where it moves through pores and cracks in the soil and rocks. Gravity pulls the water downward towards the water table or aquifers, allowing it to flow through underground pathways. Factors such as slope, soil type, and rock characteristics can influence the speed and direction of underground water movement.
A scientist who studies water is called a hydrologist. They study the distribution, movement, and properties of water on Earth, including its occurrence in rivers, lakes, and oceans, as well as underground.
If its an underground reservoir for water, it could possibly be an Aquifer.

The water movement behind the boat is called the wake. The water movement behind the boat is called the wake.
aquifers
The layer underground where all empty spaces are filled with a combination of air and water is called the vadose zone or the unsaturated zone. This zone is located above the water table and allows movement of both air and water through it.
