The slope of the Dnieper River is 11 cm / km, the length is 2285 km. Determine at what altitude above sea level the Dnieper River originates, that is, determine the height of the source of the Dnieper River.
The slope of a river is the ratio of its fall (in cm) to its length (in km).
U (river slope) = (source – mouth): L (river length), hence
hflow = Y × L – hmouth = 11 cm / km × 2285 km – 0 m = 25135 cm = 251, 35 m.
Answer: the source of the Dnieper River is located at a height of 251 m and 35 cm.
