As long as the water entered above the ground surface level.
The sea is made of water therefore all water in it is below sea level. Ground level is the surface of the dry ground. Your question therfore makes no sense.
The upper surface of water is called the water's surface or water level. It is the boundary where the water meets the air above it.
The antonym for groundwater is surface water, which refers to water that is above ground in rivers, streams, lakes, and oceans.
The damage from an earthquake can destroy underground electric mains and water pipes as a hurricane only forms above surface and can not destroy nothing under the surface and can only effect above ground level
A spring is where water rises above the ground level from a given point in the earth and a with a well, you have to dig down into the earth to reach water and then pump it up to the surface.
That is known as surface water. It can flow through rivers, streams, lakes, or other bodies of water above the ground.
A spring will flow when the water table is above where the spring exists. If no moisture replentishes the water table, or aquifier, then the spring will discontinue fo flow.
The water table is the level below the Earth's surface where the ground is saturated with water. A watershed is an area of land that drains all the streams and rainfall to a common outlet, like a river or lake. Essentially, the water table is the subsurface level of water saturation, while the watershed is the above-ground area that drains into a particular water body.
Groundwater becomes surface water when it emerges from the ground and flows above the Earth's surface, such as in streams, rivers, lakes, or wetlands. This can occur through natural processes like springs or seeps, or through human activities such as pumping from wells.
So that the water doesn't drain out of the pool and so the pool doesn't fall over. I agree with the answer above but I have a more detailed answer. In a round above ground pool the water puts even pressure on the pool walls, and if the ground is not level one side will get more pressure. The imbalance will cause the pool to collapse under the strain.
