Inflow in the Wedge influencing the net outflow through the cross section is calculated as the difference between the net outflow through the cross section and the fresh water river flow. This calculation helps in understanding the volume flowing through that specific cross section.
The calculator uses the formula:
Where:
Explanation: The formula calculates the inflow in the wedge by subtracting the fresh water river flow from the net outflow through the cross section.
Details: Accurate inflow estimation is crucial for understanding the volume dynamics in estuaries and can be approximately related to the ratio between the volume of the tidal prism and the river flow.
Tips: Enter net outflow through the cross section and fresh water river flow in m³/s. All values must be valid (non-negative).
Q1: What is the significance of inflow in the wedge?
A: Inflow in the wedge helps in understanding the mixing degree in an estuary and the volume dynamics through specific cross sections.
Q2: How is fresh water river flow measured?
A: Fresh water river flow is typically measured using flow meters or calculated based on river cross-sectional area and flow velocity.
Q3: What units are used in this calculation?
A: The calculation uses cubic meters per second (m³/s) for all flow measurements.
Q4: Can this formula be used for any estuary?
A: This formula provides a general estimation and may need adjustments based on specific estuary characteristics and conditions.
Q5: What if the calculated inflow is negative?
A: A negative inflow value may indicate that the fresh water river flow exceeds the net outflow through the cross section, which should be interpreted in the context of the specific hydrological conditions.
