Question: If a river\'s flow rate is 1000 m³/s and it carries 200 kg of sediment per cubic meter, what is the total sediment load in kilograms per second?

Options:

1. 200,000 kg/s
2. 100,000 kg/s
3. 300,000 kg/s
4. 400,000 kg/s

Correct Answer: 200,000 kg/s

Solution:

Total sediment load = Flow rate × Sediment per cubic meter = 1000 m³/s × 200 kg/m³ = 200,000 kg/s.
