Estuary Number Formula:
| From: | To: |
The Estuary Number is used in the study of estuarine circulation, which refers to the residual flow pattern in an estuary induced by the density difference between seawater and river water.
The calculator uses the Estuary Number formula:
Where:
Explanation: The Estuary Number is calculated as the square of the Froude Number divided by the Mixing Parameter, providing insight into estuarine circulation patterns.
Details: Accurate Estuary Number calculation is crucial for understanding estuarine dynamics, predicting sediment transport, and managing coastal environments affected by river-sea interactions.
Tips: Enter Froude Number and Mixing Parameter values. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the Froude Number?
A: Froude Number is the measurement of bulk flow characteristics such as waves, sand bedforms, flow or depth interactions at a cross-section or between boulders.
Q2: What does the Mixing Parameter represent?
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.
Q3: What are typical values for Estuary Number?
A: Estuary Number values vary depending on specific estuary characteristics and flow conditions, with higher values indicating stronger estuarine circulation effects.
Q4: When is this calculation most useful?
A: This calculation is particularly useful in coastal engineering, environmental studies, and hydrological research involving estuarine systems.
Q5: Are there limitations to this formula?
A: The formula provides a simplified representation and may need adjustment for specific estuary geometries, tidal conditions, or complex mixing scenarios.
