9.1.5. Demerits

Try these first

1. 1.

   What is one major demerit of the Theissen Polygon Method regarding elevation?

   Hint

   Think about how elevation affects rainfall.

2. 2.

   Why is it important to have an appropriately distributed network of rain gauge stations?

   Hint

   Consider what happens if stations are too far apart.

3. 3.

   What is a major limitation of the Theissen Polygon Method?

   • It accurately considers elevation
   • It ignores topographical influences
   • It simplifies rainfall distribution

   Hint

   Think about what features directly affect rainfall accumulation.

4. 4.

   True or False: The Theissen Polygon Method is effective in areas with uneven station distribution.

   • True
   • False

   Hint

   Reflect on what different station placements can cause in terms of data quality.

5. 5.

   Given a catchment with 4 rain gauges spread across varied elevations, analyze the potential risks involved with applying the Theissen Polygon Method. Suggest alternative methods that may offer improved accuracy.

   Hint

   Reflect on the influence of different terrains on rainfall.

6. 6.

   Consider a region where rain gauges are clustered in one area while other parts are unmonitored. Discuss the implications of this layout using the Theissen Method and present a better sampling strategy.

   Hint

   Think about the layout similar to city planning where resources must be spread efficiently.
