How to create an underground river? I became fascinated with the phenomenon of going into the ground and discovering streaming water.

Could it be possible to create an underground river and thereby make an invisible feature of the Slovenian landscape manifest itself?
In a specific area north of Ljubljana the groundwater lowers 4 meter within a distance of 200 meters. I designed a Ground Water Pavilion for that spot below the surface of the earth. Stairs lead towards a space where the groundwater is separated from the soil by open walls and streams downwards. Because the stream is connected with a lower ground water point 200 meter further south the flow is continuous.
