Inglis' Formula:
| From: | To: |
Inglis' Formula is used to calculate rainfall depth in inches for ghat areas based on runoff depth. It provides a method to estimate the total rainfall from the measured runoff in specific geographical regions.
The calculator uses Inglis' Formula:
Where:
Explanation: The formula calculates the total rainfall depth by adding 12 to the runoff depth and dividing the result by 0.85, providing an estimate of rainfall in ghat areas.
Details: Accurate rainfall depth estimation is crucial for hydrological studies, water resource management, flood prediction, and agricultural planning in ghat regions.
Tips: Enter runoff depth in inches. The value must be valid (non-negative).
Q1: What are ghat areas?
A: Ghat areas refer to mountainous or hilly regions, particularly the Western Ghats in India, known for their unique rainfall patterns and hydrological characteristics.
Q2: Why is this formula specific to ghat areas?
A: The formula accounts for the unique hydrological behavior and rainfall-runoff relationships observed in ghat regions, which differ from plain areas.
Q3: What units should be used for input?
A: Input should be in inches for runoff depth, and the result will be in inches for rainfall depth.
Q4: Are there limitations to this formula?
A: The formula is specifically calibrated for ghat areas and may not be accurate for other geographical regions with different rainfall-runoff characteristics.
Q5: How accurate is Inglis' Formula?
A: The formula provides reasonable estimates for ghat areas but should be used in conjunction with other hydrological methods for critical applications.
