15.4. Rain Gauge Network in India

Try these first

1. 1.

   What is the recommended density of rain gauges in plain areas according to IMD?

   Hint

   Look for the guidelines by the India Meteorological Department.

2. 2.

   Why is coverage across river basins important?

   Hint

   Think about how rainfall affects rivers.

3. 3.

   What is the standard density of rain gauges in hilly areas according to IMD?

   • 1 per 520 km²
   • 1 per 190 km²
   • 1 per 400 km²

   Hint

   Think about how rainfall geography impacts the number of required gauges.

4. 4.

   True or False: The density of rain gauges is the same across all terrains in India.

   • True
   • False

   Hint

   Remember the different densities for plain vs. hilly areas.

5. 5.

   You are tasked to design a network of rain gauges for a newly discovered hilly area. Describe the factors you would consider and propose a specific density.

   Hint

   Use IMD's guidelines as a starting point.

6. 6.

   Analyze the risks associated with sparse rain gauge coverage in a region prone to climate variability.

   Hint

   Think about real-life implications for agriculture and urban planning.
