27.2.6. Rainfall Characteristics

Try these first

1. 1.

   What happens when rainfall intensity exceeds infiltration capacity?

   Hint

   Think about how water behaves when it can't go anywhere.

2. 2.

   Define initial abstraction in the context of rainfall.

   Hint

   What kind of losses might happen before water soaks into the ground?

3. 3.

   What is the primary factor affecting infiltration during heavy rainfall?

   • Soil texture
   • Rainfall Intensity
   • Vegetation

   Hint

   Remember the impact of intensity on water behavior.

4. 4.

   True or False: Increased duration of rainfall never affects saturation of soil.

   • True
   • False

   Hint

   Consider the time factor in absorption.

5. 5.

   Design a small agricultural field considering the infiltration characteristics of the soil. Explain how rainfall duration and intensity could affect your planning.

   Hint

   Think about real-life applications like crop types along with seasonal rainfall patterns.

6. 6.

   Analyze a given rainfall data set. Calculate the initial abstraction rate and determine its effect on the effective rainfall available for infiltration.

   Hint

   Make sure to include all types of initial losses in your calculations.
