This document discusses the journey of a river through its drainage basin from source to mouth. It starts in highlands as a small stream that joins with other tributaries in a V-shaped valley before converging to form a larger river channel. The river then travels through lowlands on its way to emptying out at its final destination, the mouth, completing the drainage basin cycle.
