Khosla's Formula:
| From: | To: |
Khosla's Formula is used to estimate rainfall depth in inches based on runoff depth and temperature. It provides a method to calculate rainfall intensity and distribution for hydrological studies and water resource management.
The calculator uses Khosla's Formula:
Where:
Explanation: The formula accounts for the relationship between runoff depth, temperature, and resulting rainfall depth, with temperature adjustment factor based on Fahrenheit scale.
Details: Accurate rainfall depth estimation is crucial for hydrological modeling, flood prediction, irrigation planning, and water resource management in agricultural and urban environments.
Tips: Enter runoff depth in inches and temperature in Fahrenheit. Ensure valid values are provided (runoff depth ≥ 0).
Q1: What is the practical application of Khosla's Formula?
A: Khosla's Formula is primarily used in hydrological studies to estimate rainfall patterns and intensity for watershed management and irrigation planning.
Q2: Why is temperature included in the rainfall calculation?
A: Temperature affects evaporation rates and water cycle dynamics, making it an important factor in rainfall-runoff relationships.
Q3: What are typical values for runoff depth?
A: Runoff depth values vary significantly based on soil type, land use, and precipitation intensity, typically ranging from 0 to several inches.
Q4: Are there limitations to this formula?
A: The formula provides an estimation and may not account for all local factors such as soil moisture, vegetation cover, or topography.
Q5: Can this formula be used for all climate conditions?
A: While generally applicable, the formula may require calibration for specific regional conditions and extreme climate scenarios.
