22.4.2. Physically Based Methods

Try these first

1. 1.

   What does PET stand for?

   Hint

   Consider the term used when discussing water and evaporation.

2. 2.

   Which method is regarded as more accurate for PET estimation?

   Hint

   Think about the method recommended by FAO.

3. 3.

   What is the Penman-Monteith method primarily used for?

   • Estimating precipitation
   • Estimating Potential Evapotranspiration
   • Planning irrigation schedules

   Hint

   Think of its acceptance by organizations like FAO.

4. 4.

   True or False: The Penman method does not require wind speed as an input.

   • True
   • False

   Hint

   Remember all inputs necessary for the formula.

5. 5.

   Consider a region with high solar radiation and low humidity. Discuss how this combination would affect PET estimations using both the Penman and Penman-Monteith methods.

   Hint

   Evaluate all contributing factors in the formulas.

6. 6.

   Using observed data from a region, develop a case for choosing either the Penman or Penman-Monteith method based on the specific climatic conditions.

   Hint

   Assess climatic data availability and precision requirements.
