A river originates at an elevation of 800 m and enters the sea at 100 m above sea level, giving a total fall of 700 m over a length of 120 km. A waterfall dropping 50 m is located 30 km downstream from the source. Apart from the waterfall, the river has a uniform gradient upstream of the waterfall and a different uniform gradient downstream. If the upstream gradient (excluding the waterfall) is twice the downstream gradient, calculate the average gradient (in metres per kilometre, to one decimal place) of the upstream and downstream reaches.

Answer Options

A. Upstream gradient ≈ 9.5 m\/km, downstream gradient ≈ 4.8 m\/km
B. Upstream gradient ≈ 10.0 m\/km, downstream gradient ≈ 5.0 m\/km
Correct Answer C. Upstream gradient ≈ 8.7 m/km, downstream gradient ≈ 4.3 m/km
D. Upstream gradient ≈ 7.0 m\/km, downstream gradient ≈ 3.5 m\/km
Correct Answer
C
Correct Option:
Upstream gradient ≈ 8.7 m/km, downstream gradient ≈ 4.3 m/km
