The correct answer is option D: The distance between the rain gauge and the nearest object should be at least twice the height of the object.
Explanation:
When selecting a site for a rain gauge station, several factors need to be considered to ensure accurate measurement of rainfall. The distance between the rain gauge and the nearest object is an important criterion to keep in mind. Here's why this is the correct answer:
1. Minimize Obstruction:
The purpose of a rain gauge is to measure the amount of rainfall received at a particular location. To obtain accurate measurements, it is crucial to minimize any obstructions that could interfere with the collection of rainwater. Placing the rain gauge too close to an object, such as a tree or a building, might result in the obstruction of rainwater flow, leading to inaccurate measurements.
2. Avoid Splashing:
Rainfall measurements can be affected by splashing or rebounding of raindrops. Placing the rain gauge at a distance from the nearest object helps to minimize splashing caused by raindrops hitting the ground or other surfaces and bouncing into the gauge. This reduces the chances of measurement errors due to splashing.
3. Wind Effects:
Wind can also have an impact on rainfall measurements. Placing the rain gauge too close to an object can create a wind tunnel effect, where the wind is funneled between the object and the gauge. This can result in altered wind patterns and may cause rainfall to be deflected away from the gauge, leading to inaccurate measurements. By maintaining a distance of at least twice the height of the object, the impact of wind on rainfall measurements can be minimized.
4. Avoid Contamination:
Another important consideration is to prevent contamination of the rain gauge. Placing the gauge too close to objects such as trees, buildings, or other structures can lead to debris, bird droppings, or other contaminants falling into the gauge, affecting the accuracy of the measurements. By maintaining a sufficient distance, the risk of contamination can be reduced.
Conclusion:
In conclusion, when selecting a site for a rain gauge station, it is essential to consider the distance between the rain gauge and the nearest object. This criterion helps to minimize obstructions, avoid splashing, reduce wind effects, and prevent contamination, ultimately ensuring accurate measurements of rainfall.

While selecting the site for rain gauge stations the following points should be considered:
- The site should be on level ground and on open space. It should never be on sloping ground.
- The site should be such that the distance between the gauge station and the objects (like a tree, building, etc) should be at least twice the height of the objects.
- In the hilly area, where level ground is not available, the site should be so selected that the station may be well shielded from high wind.
- The site should be easily accessible to the observer.
- The site should be well protected from cattle by wire fencing.
