9.2.5. Demerits

Try these first

1. 1.

   Name one demerit of the Isohyetal Method.

   Hint

   Think about the length of the process involved.

2. 2.

   What does the subjective element in the Isohyetal Method refer to?

   Hint

   Consider who is drawing the isohyets.

3. 3.

   What is one major demerit of the Isohyetal Method?

   • Time-consuming
   • Highly accurate
   • Automatically generated

   Hint

   Remember how long it takes to create detailed rainfall maps.

4. 4.

   True or False: The Isohyetal Method is not subjective in nature.

   • True
   • False

   Hint

   Think about who does the drawing.

5. 5.

   Consider a region where the Isohyetal Method is applied but lacks a dense network of rain gauges. What potential inaccuracies might arise, and how could this affect water resource management?

   Hint

   Think about what could go wrong if there isn’t enough data to draw accurate conclusions.

6. 6.

   Design a case study where you outline the use of the Isohyetal Method across different scenarios, mentioning the differences in results based on the density of rain gauges.

   Hint

   Consider two maps of rainfall estimates corresponding to different numbers of rain gauges.
