Show Hint
Interception: water caught by vegetation.
Throughfall: water that reaches the ground.
Return period: probability of occurrence.
Throughfall: water that reaches the ground.
Return period: probability of occurrence.

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Hydrological aspects of rainfall include various concepts and methods.
We need to identify the correct statements.
Step 2: Key Formula or Approach:
No specific formula.
Need to know each concept.
Step 3: Detailed Explanation:
A. Cetyl alcohol is used as an evaporation inhibitor - correct.
B. Isohyetal, Thiessen polygon, and arithmetic-mean methods are used for areal rainfall distribution - correct.
C. Falling raindrops intercepted by vegetation is called interception, not throughfall.
Throughfall is the water that reaches the ground after interception.
Thus, C is incorrect.
D. Return period is the probability of occurrence of an event - correct.
E. DAD (Depth-Area-Duration) curves are used to estimate severe floods - correct.
Thus, A, B, D, and E are correct.
Step 4: Final Answer:
The correct statements are A, B, D, and E.
Hence, the correct option is (D).
