Question

Given below are two statements:
Statement (I): Record from the tipping bucket gives data on the rainfall intensity.
Statement (II): Natural siphon-type recording raingauge gives a plot of the mass curve of rainfall.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

- Tipping Bucket = Best for digital rainfall intensity.
- Natural Siphon / Float Type = Traces the cumulative mass curve of rainfall.
Both statements are standard facts in hydrology.

Answer 1

The Correct Option is A

Step 1: Recall what a tipping bucket gauge physically records.
A tipping bucket rain gauge tips and sends a signal each time a fixed small volume of rain has collected, and the time interval between successive tips is logged. Since intensity is depth of rain divided by time, the tip timestamps directly give the rate at which rain is falling at any moment, so Statement I is correct.
Step 2: Recall what a natural siphon, float type gauge physically records.
This gauge uses a float that rises with the water level in a collection chamber and drives a pen across a rotating chart, producing a continuous trace of cumulative rainfall against time. That cumulative rainfall versus time trace is precisely the definition of a mass curve of rainfall, so Statement II is also correct.
Step 3: Cross check by contrast.
The two instruments are complementary rather than doing the same job, one reveals intensity peaks and the other reveals the running total, which confirms both descriptions are accurate rather than one being a misattributed feature of the other.
\[ \boxed{Both Statement (I) and Statement (II) are correct.} \]
