15.4.1. IMD Norms

Try these first

1. 1.

   What is the recommended distance for rainfall gauge stations in plain areas according to IMD?

   Hint

   Think about how plains typically have less variation.

2. 2.

   True or False: In hilly areas, IMD recommends a greater density of rain gauges than in plain areas.

   Hint

   Consider how elevation affects rainfall.

3. 3.

   What is the IMD's recommended spacing of rain gauge stations in plain areas?

   • 1 station per 100 km²
   • 1 station per 200 km²
   • 1 station per 520 km²

   Hint

   Think about how much area one gauge can effectively monitor.

4. 4.

   True or False: IMD recommends greater gauge station density in heavy rainfall areas compared to hilly areas.

   • True
   • False

   Hint

   Consider the risks associated with heavy rainfall.

5. 5.

   If you were tasked to design a rainfall data collection network over a 2500 km² area that consists of both flat and hilly regions, what factors would you consider in planning the placement of gauge stations?

   Hint

   Think about how each terrain may receive rainfall differently.

6. 6.

   Assuming a region is experiencing climate change, leading to unpredictable rainfall patterns, how would that impact the IMD's rain gauge recommendations?

   Hint

   Consider the need for adaptability in regulatory frameworks.
