A river descends from an elevation of 800 m at its source to 200 m at its mouth, covering a total length of 150 km. The upper course (first 40 km) drops uniformly, the middle course (next 80 km) drops uniformly, and the lower course (remaining 30 km) drops uniformly. The gradient of the middle course is four times that of the lower course, and the gradient of the upper course is 1.5 times the gradient of the lower course.
