Try these first

1. 1.

   What is the formula for the Pan Evaporation Method?

   Hint

   Think about what each letter represents.

2. 2.

   List one key component of the Water Budget Method.

   Hint

   Recall the mass balance equation.

3. 3.

   What method uses pan data to estimate evaporation?

   • Energy Budget Method
   • Water Budget Method
   • Pan Evaporation Method

   Hint

   Think about the simplest method discussed.

4. 4.

   True or False: The Energy Budget Method does not require any data on heat fluxes.

   • True
   • False

   Hint

   Recall what this method is based upon.

5. 5.

   If a reservoir has dimensions affecting evaporation differently, describe how you would choose which estimation method to use.

   Hint

   Think about the scale and data requirements.

6. 6.

   Critique the tradeoffs between using traditional methods versus Remote Sensing for estimating evaporation in a semi-arid region.

   Hint

   Consider both methods' strengths and weaknesses.
