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. It's a crucial parameter in coastal engineering and estuarine studies.
The calculator uses the formula:
Where:
Explanation: The mixing parameter represents the degree of mixing in an estuary and can be approximately related to the ratio between the volume of the tidal prism and the river flow.
Details: Accurate calculation of tidal prism volume is essential for understanding estuarine dynamics, sediment transport, water quality management, and designing coastal structures.
Tips: Enter fresh water river flow in m³/s, tidal period in seconds, and mixing parameter. All values must be positive numbers greater than zero.
Q1: What is the typical range for mixing parameter values?
A: Mixing parameter values typically range from 1 to 100, depending on the specific estuary characteristics and tidal conditions.
Q2: How is tidal period measured?
A: Tidal period is the time between successive high tides, typically approximately 12 hours and 25 minutes (44,700 seconds) for semi-diurnal tides.
Q3: What factors affect the mixing parameter?
A: The mixing parameter is influenced by estuary geometry, tidal range, river discharge, and stratification effects.
Q4: Can this formula be used for all types of estuaries?
A: While generally applicable, the formula may need adjustments for highly stratified or well-mixed estuaries with unique characteristics.
Q5: How accurate is this calculation method?
A: The method provides a good estimate for preliminary calculations, but for precise engineering applications, more detailed hydrodynamic modeling may be required.
