Questions & Step-by-Step Solutions
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)
Step 1: Understand the area of the river basin, which is given as 500 km².
Step 2: Convert the area from square kilometers to square meters. 1 km² = 1,000,000 m², so 500 km² = 500 × 1,000,000 m² = 500,000,000 m².
Step 3: Understand the average rainfall, which is given as 800 mm. Convert this to meters. 800 mm = 0.8 m.
Step 4: Calculate the volume of water received by the basin using the formula: Volume = Area × Rainfall.
Step 5: Substitute the values into the formula: Volume = 500,000,000 m² × 0.8 m.
Step 6: Perform the multiplication: 500,000,000 m² × 0.8 m = 400,000,000 m³.
Step 7: The total volume of water received by the basin is 400,000,000 m³.
Area and Volume Calculation – Understanding how to calculate the volume of water based on area and rainfall measurements.
Unit Conversion – Converting rainfall from millimeters to meters to ensure consistent units when calculating volume.
