Fresh Water River Flow is 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. It represents the net freshwater contribution to the estuarine system.
The calculator uses the formula:
Where:
Explanation: The formula calculates the freshwater river flow by subtracting the wedge inflow from the net outflow through the cross section.
Details: Accurate calculation of freshwater river flow is crucial for understanding estuarine dynamics, salinity distribution, and ecological processes in coastal environments.
Tips: Enter net outflow through cross section and inflow in the wedge in m³/s. Both values must be valid non-negative numbers.
Q1: What is the significance of freshwater river flow in estuaries?
A: Freshwater river flow determines the degree of stratification, salt intrusion length, and overall mixing characteristics in estuarine systems.
Q2: How does wedge inflow affect the net outflow calculation?
A: Wedge inflow represents additional water entering the system that must be accounted for when calculating the true freshwater contribution.
Q3: What are typical values for freshwater river flow?
A: Values vary significantly depending on river size, season, and geographical location, ranging from small streams to major river systems.
Q4: Are there limitations to this calculation method?
A: This method provides an approximation and may need adjustment for complex estuarine geometries or highly dynamic flow conditions.
Q5: How often should these measurements be taken?
A: Regular monitoring is recommended, especially during different tidal conditions and seasonal variations in river discharge.
