An underground river is formed when the uppermost surface of the earth easily allows rainwater to pass through to a more solid soil-structure. This water starts flowing due to the pressure of the upper water and takes the shape of an under ground river.
They are rivers that flow underground rather than on the surface. They are usually found in limestone areas and are responsible for forming cave systems. (they can also form under Ice sheets).
In huge underground lakes and rivers. Also, underground the Earth.
