1. What is Portion caused by Filling?

Portion caused by Filling influences the Ratio of Water Volume entering the Harbor per Tide to the Harbor Volume. It is an important parameter in harbor hydraulics and tidal analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \alpha_f \) — Portion caused by Filling
• \( \Delta h \) — Difference between High and Low Tide level (Meter)
• \( h' \) — Average Harbor Depth (Meter)

Explanation: The formula calculates the portion of harbor filling by comparing the tidal range with the average harbor depth.

3. Importance of Portion caused by Filling Calculation

Details: Accurate calculation of Portion caused by Filling is crucial for harbor design, tidal analysis, and understanding water exchange patterns in harbor basins.

4. Using the Calculator

Tips: Enter the difference between high and low tide level and average harbor depth in meters. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range of Portion caused by Filling values?
A: The value typically ranges between 0 and 1, but can exceed 1 in cases where tidal range is greater than harbor depth.

Q2: How does Portion caused by Filling affect harbor operations?
A: Higher values indicate greater water exchange during tidal cycles, which can affect sedimentation, water quality, and navigation conditions.

Q3: When should this calculation be used?
A: This calculation is essential during harbor design, expansion projects, and environmental impact assessments of harbor facilities.

Q4: Are there limitations to this formula?
A: The formula provides a simplified estimation and may not account for complex harbor geometries, wind effects, or other hydrodynamic factors.

Q5: How does this relate to tidal prism calculations?
A: Portion caused by Filling is directly related to tidal prism calculations and helps determine the volume of water entering and leaving the harbor during each tidal cycle.
