21.3.5. Limitations of Blaney and Criddle Method

Try these first

1. 1.

   What are the main limitations of the Blaney and Criddle method?

   Hint

   Think about what factors affect evapotranspiration.

2. 2.

   In what type of regions is the Blaney and Criddle method most applicable?

   Hint

   Consider the water availability in a region.

3. 3.

   What is one primary factor that the Blaney and Criddle method does not consider?

   • Humidity
   • Temperature
   • Precipitation

   Hint

   No hint provided

4. 4.

   True or False: The Blaney and Criddle method is more accurate than the Penman method.

   • True
   • False

   Hint

   No hint provided

5. 5.

   Given a scenario where a region has high humidity and varying wind speeds, discuss why the Blaney and Criddle method may fail in predicting the actual evapotranspiration.

   Hint

   Consider how these factors directly impact the crop's water loss.

6. 6.

   Design a research proposal to quantify the difference in water use efficiency between crops if assessed using both the Blaney and Criddle method and the Penman method over a two-year period.

   Hint

   Outline the parameters and data collection techniques needed for both methods.
