Formula For Runoff In Very Hilly, Steep And Hardly Any Cultivation Catchment With Light Rain:
| From: | To: |
This formula calculates runoff in very hilly, steep areas with hardly any cultivation during light rain conditions. It provides an estimate of water runoff based on rainfall measurements.
The calculator uses the formula:
Where:
Explanation: The formula applies a coefficient of 0.36 to estimate runoff in very hilly, steep terrain with minimal cultivation during light rain conditions.
Details: Accurate runoff estimation is crucial for water resource management, flood prediction, and agricultural planning in hilly terrain with specific land use characteristics.
Tips: Enter rainfall measurement in centimeters. The value must be valid (rainfall > 0).
Q1: When is this formula applicable?
A: This formula is specifically designed for very hilly, steep terrain with hardly any cultivation during light rain conditions.
Q2: How was the coefficient 0.36 determined?
A: The coefficient is derived from empirical studies of runoff patterns in hilly, steep terrain with minimal cultivation during light rainfall events.
Q3: Can this formula be used for heavy rainfall?
A: No, this formula is specifically calibrated for light rain conditions and may not be accurate for heavy rainfall events.
Q4: What factors affect runoff in hilly terrain?
A: Slope gradient, soil type, vegetation cover, rainfall intensity, and land use practices all significantly influence runoff in hilly areas.
Q5: How accurate is this estimation method?
A: While providing a reasonable estimate, actual runoff can vary based on specific local conditions not captured by this simplified formula.
