3. Analytical Methods for Estimating Evaporation

Try these first

1. 1.

   What is evaporation?

   Hint

   Think about water cycles.

2. 2.

   Name one method to estimate evaporation.

   Hint

   Recall methods we discussed.

3. 3.

   Which method combines aerodynamic and energy balance?

   • Thornthwaite Method
   • Energy Budget Method
   • Penman’s Equation

   Hint

   Remember the key contributor to evaporation estimates.

4. 4.

   True or False: The Thornthwaite method requires extensive meteorological data.

   • True
   • False

   Hint

   Think about the data it uses.

5. 5.

   A researcher has temperature data for a region and needs to estimate potential evapotranspiration using the Thornthwaite method. Outline the steps they should take.

   Hint

   What data does the Thornthwaite method primarily depend on?

6. 6.

   Given a set of inflow and outflow measurements, design a simple model to compute evaporation for a local pond using the Water Budget method. What parameters would you use?

   Hint

   How do inflow and outflow relate to overall water management?
