1. What is Tidal Period?

Tidal Period is the time taken for a specific site on Earth to rotate from an exact point under moon to same point under moon, also known as "tidal day" and it's slightly longer than a solar day.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Tidal Period (seconds)
• \( M \) — Mixing Parameter
• \( P \) — Volume of Tidal Prism (m³)
• \( Q_r \) — Fresh Water River Flow (m³/s)

Explanation: This formula calculates the tidal period based on the mixing parameter, volume of tidal prism, and fresh water river flow rate.

3. Importance of Tidal Period Calculation

Details: Accurate tidal period calculation is crucial for coastal engineering, navigation, and understanding estuarine dynamics and mixing processes.

4. Using the Calculator

Tips: Enter mixing parameter, volume of tidal prism in cubic meters, and fresh water river flow in cubic meters per second. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the mixing parameter?
A: Mixing parameter is the degree of mixing in an estuary which can be approximately related to the ratio between the volume of the tidal prism and the river flow.

Q2: How is volume of tidal prism defined?
A: Volume of tidal prism is the volume of water in an estuary or inlet between mean high tide and mean low tide, or the volume of water leaving an estuary at ebb tide.

Q3: What units should be used for fresh water river flow?
A: Fresh water river flow should be measured in cubic meters per second (m³/s) for consistent calculations.

Q4: Are there limitations to this formula?
A: This formula provides an approximation and may not account for all complex hydrodynamic factors in specific estuarine environments.

Q5: How accurate is this calculation for real-world applications?
A: While useful for estimation purposes, field measurements and more complex hydrodynamic models may be needed for precise engineering applications.
