Questions & Step-by-Step Solutions

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)
  • Step 1: Identify the sediment transport capacity of the river, which is 200 kg/m³.
  • Step 2: Identify the flow rate of the river, which is 10 m³/s.
  • Step 3: Determine the time period for which we want to calculate the total sediment transported. In this case, it is 1 hour, which is equal to 3600 seconds.
  • Step 4: Use the formula for total sediment transported: Total sediment = Sediment capacity × Flow rate × Time.
  • Step 5: Plug in the values: Total sediment = 200 kg/m³ × 10 m³/s × 3600 s.
  • Step 6: Calculate the total sediment: 200 × 10 = 2000 kg/s, then multiply by 3600 seconds to get 2000 kg/s × 3600 s = 7200000 kg.
  • Step 7: Conclude that the total sediment transported in one hour is 7200000 kg.
  • Sediment Transport Capacity – Understanding how to calculate the total sediment transported based on sediment capacity, flow rate, and time.
  • Flow Rate – Recognizing the importance of flow rate in determining the volume of sediment transported.
  • Time Conversion – Converting time from hours to seconds to ensure consistency in units during calculations.
