A plot between rainfall intensity versus time is called?

GPSC AE (CLASS 1 & 2) 2019

⭕ (a) Isohyet

⭕ (b) Mass curve

⭕ (c) Hyetograph

⭕ (d) Hydrograph

Explanation: A Hyetograph is a bar diagram that represents rainfall intensity versus time.

• Rainfall intensity is plotted on the ordinate (Y-axis).
• Time is plotted on the abscissa (X-axis).
• This is useful in hydrological studies and storm water analysis.

Rainfall Intensity vs Time Graph in Hydrology

This MCQ from GPSC AE 2019 asks about the name of the graph that shows rainfall intensity against time — a key concept in hydrology and environmental engineering.

Important Hydrological Graphs:

• Hyetograph: Rainfall intensity vs time
• Hydrograph: Discharge vs time
• Mass Curve: Cumulative rainfall vs time
• Isohyet: Contour of equal rainfall

Conclusion:

The correct answer is Hyetograph. It is a crucial tool used in rainfall analysis and water resources planning, often asked in AE, JE, and UPSC exams.
