Rivers carve through landscapes, shaping Earth.

Rivers not only flow on the surface but also underground, creating intricate networks that sustain ecosystems and provide vital resources. These hidden waterways, known as subterranean rivers, play a crucial role in maintaining the balance of water distribution and supporting diverse flora and fauna.
