Weighted Mean Slope Formula:
| From: | To: |
Weighted Mean Slope derived for peak discharge is calculated by multiplying the weight (or probability) associated with a particular event or outcome. It is an important parameter in hydrological studies for understanding watershed characteristics.
The calculator uses the Weighted Mean Slope formula:
Where:
Explanation: The equation calculates the weighted mean slope based on the peak discharge and catchment area, providing insights into the watershed's hydrological characteristics.
Details: Accurate calculation of weighted mean slope is crucial for hydrological modeling, flood prediction, and watershed management. It helps in understanding the relationship between discharge and catchment characteristics.
Tips: Enter peak discharge in m³/s and catchment area in m². All values must be valid (greater than 0).
Q1: What is the significance of the 37.4 constant in the formula?
A: The constant 37.4 is derived from empirical studies and represents the relationship between discharge, area, and slope in hydrological systems.
Q2: How does catchment area affect the weighted mean slope?
A: Larger catchment areas generally result in smaller weighted mean slope values, as the discharge is distributed over a larger area.
Q3: What are typical values for weighted mean slope?
A: Values vary depending on watershed characteristics, but typically range from 0.001 to 0.1 for most hydrological applications.
Q4: Can this formula be used for all types of watersheds?
A: While generally applicable, the formula may need adjustments for extreme topography or unusual hydrological conditions.
Q5: How accurate is this calculation method?
A: The method provides good estimates for most practical applications, but field measurements may be needed for precise engineering designs.
