Q. If a river basin has an area of 2000 km² and receives an average rainfall of 800 mm per year, what is the total volume of water received by the basin in cubic meters? (2000)
A.
1600000000
B.
16000000
C.
160000000
D.
16000000000
Solution
Volume = Area × Rainfall = 2000 km² × 800 mm = 2000 × 10^6 m² × 0.8 m = 1600000000 m³.
Q. If a river basin has an area of 500 km² and receives an average rainfall of 800 mm annually, what is the total volume of water received by the basin in cubic meters? (2022)
A.
400,000,000 m³
B.
500,000,000 m³
C.
600,000,000 m³
D.
700,000,000 m³
Solution
Volume = Area × Rainfall = 500 km² × 800 mm = 500,000,000 m³.
Q. If a river has a discharge of 500 cubic meters per second and the cross-sectional area of the river is 100 square meters, what is the velocity of the river?
A.
2 m/s
B.
5 m/s
C.
10 m/s
D.
20 m/s
Solution
Velocity = Discharge / Area = 500 m³/s / 100 m² = 5 m/s.
Q. If a river has a sediment transport capacity of 200 kg/m³ and flows at a rate of 10 m³/s, what is the total sediment transported in one hour? (2000)
A.
72000 kg
B.
60000 kg
C.
360000 kg
D.
120000 kg
Solution
Total sediment = Sediment capacity × Flow rate × Time = 200 kg/m³ × 10 m³/s × 3600 s = 7200000 kg.
Q. If a river is 300 meters wide and the current flows at 2 m/s, how long will it take a swimmer to cross the river if he swims at a speed of 1 m/s perpendicular to the current?
A.
300 seconds
B.
150 seconds
C.
200 seconds
D.
100 seconds
Solution
Time to cross = Width / Speed across = 300 m / 1 m/s = 300 seconds.
Q. If a river's pollution level is reduced by 25% and the current level is measured at 200 units, what will be the pollution level after the reduction?
A.
150 units
B.
175 units
C.
200 units
D.
180 units
Solution
25% of 200 = 0.25 * 200 = 50 units. New pollution level = 200 - 50 = 150 units.
Q. If a river's width increases from 50 meters to 100 meters while maintaining the same depth of 3 meters, what is the change in cross-sectional area? (2022)
A.
150 m²
B.
200 m²
C.
300 m²
D.
400 m²
Solution
Initial area = 50 m × 3 m = 150 m²; Final area = 100 m × 3 m = 300 m²; Change = 300 m² - 150 m² = 150 m².
