8.7. Application of Areal Rainfall in Hydrologic Studies

Try these first

1. 1.

   What is areal rainfall?

   Hint

   Think about rainfall data collection.

2. 2.

   Name one application of areal rainfall.

   Hint

   Consider the implications of rainfall on water flow.

3. 3.

   What does areal rainfall provide for hydrologic studies?

   • Only point data
   • The average rainfall over an area
   • Irrigation planning

   Hint

   Think about its role in hydrological modeling.

4. 4.

   True or False: Areal rainfall is not crucial for flood frequency analysis.

   • True
   • False

   Hint

   Consider how rainfall affects flooding.

5. 5.

   A reservoir is designed to hold runoff from a 100-square-mile catchment area. If historical areal rainfall data indicates a 5-inch average over the design period, how much total runoff should be expected (in cubic feet)?

   Hint

   Remember to convert all units to the same system before calculating.

6. 6.

   A farmer is analyzing the average areal rainfall of his region over a decade. If he notices a consistent decrease in rainfall, what strategies can he implement to adapt?

   Hint

   Think about how farmers can adapt to changes in rainfall.
