51.4.4. Rainfall and Irrigation Intensity

Try these first

1. 1.

   What is rainfall intensity?

   Hint

   Look for definitions related to precipitation.

2. 2.

   Name one effect of using flood irrigation.

   Hint

   Think about the capacity of soil to absorb water.

3. 3.

   What is rainfall intensity?

   • Rate of evaporation
   • Rate of precipitation
   • Soil saturation level

   Hint

   Consider how scientists measure precipitation.

4. 4.

   True or False: Higher irrigation intensity can lead to faster waterlogging in soils.

   • True
   • False

   Hint

   Think about how soil holds water.

5. 5.

   Design a drainage plan incorporating varying rainfall patterns alongside a specific irrigation method in a region experiencing periodic drought and flooding.

   Hint

   Consider the extremes of water usage in your design.

6. 6.

   Analyze the potential consequences of using heavy flood irrigation in a high-rainfall region without a proper drainage system.

   Hint

   Focus on how the excess water impacts the soil's ability to support crops.
