1. What is the Flood Coefficient?

The Flood Coefficient refers to a constant value which depends upon catchment and flood characteristics. It is used in hydrological calculations to relate flood discharge to catchment area and flood severity.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( CF \) — Flood Coefficient
• \( Qfe \) — Flood discharge (m³/s)
• \( Afd \) — Catchment area for flood discharge (m²)
• \( n \) — Flood Index

Explanation: The formula calculates the flood coefficient by dividing the flood discharge by the catchment area raised to the power of the flood index.

3. Importance of Flood Coefficient Calculation

Details: Accurate flood coefficient calculation is crucial for flood risk assessment, hydraulic engineering design, and watershed management planning.

4. Using the Calculator

Tips: Enter flood discharge in m³/s, catchment area in m², and flood index. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical range for flood coefficient values?
A: Flood coefficient values vary significantly depending on catchment characteristics, but typically range from 0.01 to 10.0.

Q2: How does the flood index affect the calculation?
A: The flood index represents the severity of flood events and significantly influences the flood coefficient calculation.

Q3: When should this calculation be used?
A: This calculation is used in hydrological studies, flood forecasting, and hydraulic structure design.

Q4: Are there limitations to this formula?

Q5: How accurate is this calculation?
A: Accuracy depends on the precision of input values and the appropriateness of the flood index for the specific catchment area.
