1. What is Depth of Flow?

Depth of Flow is the distance from the top or surface of the flow to the bottom of a channel or other waterway or Depth of Flow at the Vertical while measuring Sound Weights.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( d_f \) — Depth of Flow (m)
• \( A_{Para} \) — Wetted Surface Area of Parabola (m²)
• \( T \) — Top Width (m)

Explanation: This formula calculates the depth of flow in a parabolic channel section based on the wetted surface area and top width measurements.

3. Importance of Depth Calculation

Details: Accurate depth of flow calculation is crucial for hydraulic engineering, channel design, flood prediction, and water resource management. It helps determine flow characteristics and capacity of water channels.

4. Using the Calculator

Tips: Enter the wetted surface area of the parabola in square meters and the top width in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is wetted surface area in a parabolic channel?
A: Wetted surface area refers to the total area of the channel cross-section that is in contact with flowing water.

Q2: How is top width measured in parabolic channels?
A: Top width is measured as the horizontal distance across the water surface at the top of the flow section.

Q3: Why is the constant 1.5 used in this formula?
A: The constant 1.5 is derived from the geometric properties of parabolic sections and represents the relationship between area, width, and depth.

Q4: What are typical applications of this calculation?
A: This calculation is used in irrigation channel design, stormwater management, river engineering, and hydraulic structure design.

Q5: Are there limitations to this formula?
A: This formula is specific to parabolic channel sections and may not be accurate for other channel shapes such as rectangular, trapezoidal, or circular sections.
