Questions & Step-by-Step Solutions

A river has a length of 100 km and a drainage area of 500 km². What is the average discharge per square kilometer?
  • Step 1: Understand the problem. We need to find the average discharge per square kilometer of the river's drainage area.
  • Step 2: Identify the total discharge. In this case, it is given as 250 m³/s.
  • Step 3: Identify the drainage area. The drainage area is given as 500 km².
  • Step 4: Use the formula for average discharge: Average discharge = Total discharge / Drainage area.
  • Step 5: Plug in the values: Average discharge = 250 m³/s / 500 km².
  • Step 6: Calculate the average discharge: 250 m³/s divided by 500 km² equals 0.5 m³/s.
  • Discharge Calculation – Understanding how to calculate average discharge using total discharge and drainage area.
  • Units of Measurement – Recognizing the importance of consistent units when calculating discharge per area.
