1. What is Maximum 30-Minutes Rainfall Intensity?

Maximum 30-Minutes Rainfall Intensity of the storm is the amount of maximum precipitation for a 30-minute duration in a day. It is a crucial parameter in hydrology and erosion studies.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( I_{30} \) — Maximum 30-Minutes Rainfall Intensity (m/s)
• \( EI_{30} \) — Rainfall Erosion Index Unit
• \( KE \) — Kinetic Energy of the Storm (Joule)

Explanation: This formula calculates the maximum rainfall intensity over a 30-minute period based on the rainfall erosion index and the kinetic energy of the storm.

3. Importance of Rainfall Intensity Calculation

Details: Accurate rainfall intensity calculation is crucial for flood prediction, drainage system design, soil erosion studies, and water resource management.

4. Using the Calculator

Tips: Enter Rainfall Erosion Index Unit and Kinetic Energy of the Storm. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is Rainfall Erosion Index Unit?
A: Rainfall Erosion Index Unit is a measure of the ability of rainfall to cause soil erosion. It is a numerical value that expresses the potential of rainfall to erode soil particles.

Q2: How is Kinetic Energy of the Storm measured?
A: Kinetic Energy of the Storm is typically measured in Joules and represents the energy that rainfall possesses due to its motion.

Q3: Why is 30-minute duration specifically used?
A: The 30-minute duration is a standard time interval used in hydrology for analyzing short-term rainfall intensity patterns and their impact on erosion and runoff.

Q4: What are typical values for Maximum 30-Minutes Rainfall Intensity?
A: Values vary by region and storm intensity, but typically range from 0.001 to 0.1 m/s depending on climatic conditions.

Q5: How accurate is this calculation method?
A: The formula provides a good estimate but actual measurements may vary due to local atmospheric conditions and measurement techniques.
