Question:
The graph between intensity of precipitation and time is represented as:
The graph between intensity of precipitation and time is represented as:
Show Hint
Differentiate the two common rainfall graphs: Hyetograph = Intensity vs Time and Mass Curve = Cumulative Rainfall vs Time.
Updated On: Aug 24, 2026
- Bar chart
- Rainfall spectrum
- Mass curve
- Hyetograph
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
A hyetograph is the standard graphical representation of rainfall intensity over time and is widely used in hydrology for runoff estimation and storm analysis.
Step 2: Detailed Explanation:
A Hyetograph uses vertical bars to represent rainfall intensity during successive time intervals. It helps identify peak rainfall intensity and storm duration.
A Mass Curve represents cumulative rainfall rather than intensity.
A Bar chart is only a general plotting method and is not the technical hydrological term.
Therefore, the graph of precipitation intensity versus time is called a hyetograph.
Step 3: Final Answer:
The correct answer is (D) Hyetograph.
A hyetograph is the standard graphical representation of rainfall intensity over time and is widely used in hydrology for runoff estimation and storm analysis.
