The Average Harbor Depth Given Portion Caused By Filling is a calculation used in harbor engineering to determine the average depth of a harbor based on tidal differences and filling factors. This measurement is crucial for harbor design and navigation safety.
The calculator uses the formula:
Where:
Explanation: This formula calculates the average harbor depth by dividing the tidal difference by the portion caused by filling, which represents the ratio of water volume entering the harbor per tide to the harbor volume.
Details: Accurate harbor depth calculation is essential for safe navigation, proper harbor design, dredging operations, and ensuring vessels can enter and exit the harbor safely during different tidal conditions.
Tips: Enter the difference between high and low tide levels in meters and the portion caused by filling (unitless). Both values must be positive numbers greater than zero.
Q1: What is the typical range for portion caused by filling?
A: The portion caused by filling typically ranges between 0.1 and 0.8, depending on harbor geometry and tidal characteristics.
Q2: How is tidal difference measured?
A: Tidal difference is measured as the vertical distance between high tide and low tide levels, typically using tide gauges or water level sensors.
Q3: Why is average harbor depth different from regular port depth?
A: Average harbor depth accounts for tidal variations and filling effects, providing a more comprehensive measurement for harbor operations and design.
Q4: What factors influence the portion caused by filling?
A: Harbor geometry, tidal range, basin shape, and entrance configuration all influence the portion caused by filling.
Q5: How accurate is this calculation for harbor design?
A: While this formula provides a good estimate, actual harbor design should consider additional factors such as sediment transport, wave action, and long-term morphological changes.
