Inlet Current Wave Height Factor Equation:
| From: | To: |
The Inlet Current Wave Height Factor (Rh) is the ratio between the wave height and the wave height entering an inlet. It provides important information about wave transformation and energy dissipation as waves propagate through inlets and coastal structures.
The calculator uses the Inlet Current Wave Height Factor equation:
Where:
Explanation: This simple ratio indicates how much the wave height changes as it enters and propagates through an inlet, providing insights into wave energy transformation and coastal processes.
Details: Calculating the wave height factor is crucial for coastal engineering, navigation safety, sediment transport studies, and understanding how wave energy is modified as waves enter inlets, harbors, and other coastal features.
Tips: Enter both wave height values in meters. Ensure both values are positive and measured consistently. The result is a dimensionless ratio that indicates the relative change in wave height.
Q1: What does a Rh value greater than 1 indicate?
A: A value greater than 1 indicates wave amplification, where the wave height increases as it enters the inlet, which can occur due to wave focusing or other hydrodynamic processes.
Q2: What does a Rh value less than 1 indicate?
A: A value less than 1 indicates wave attenuation, where the wave height decreases due to energy dissipation, refraction, diffraction, or other wave transformation processes.
Q3: When is this calculation typically used?
A: This calculation is commonly used in coastal engineering, harbor design, navigation studies, and environmental impact assessments of coastal structures.
Q4: Are there limitations to this simple ratio?
A: While useful, this simple ratio doesn't account for wave period, direction, or complex bathymetric effects that may influence wave transformation in inlets.
Q5: How should wave measurements be taken for accurate results?
A: Wave measurements should be taken simultaneously at consistent locations using wave gauges or other reliable measurement techniques to ensure accurate comparison.
