Hello! here is your answer
A river begins on high ground or in hills or mountains and flows down from the high ground to the lower ground, because of gravity.
Mountain river is a river that runs usually in mountains, in narrow, deep valley with steep banks, rocky stream bed, and accumulated rock debris.
Mountain rivers are characterized by high slope and flow velocity, insignificant depth, frequent rapids and waterfalls, dominated washed out processes. The gradient of mountain river is calculated at 60–80 m/km in upper stream and 5–10 m/km in lower. More precisely it is greater than or equal to 0.002 m/m along most of its stream length. Speed of stream is measured at 1 to 4.5 m/s and higher.
