Deep-Water Wavelength is the horizontal distance between two successive crests (or troughs) of the wave in deep water conditions. It's a fundamental parameter in wave behavior analysis and coastal engineering.
The calculator uses the formula:
Where:
Explanation: This formula calculates the deep-water wavelength based on the equivalent unrefracted deepwater wave height and the breaker height index, which is the ratio of wave height to still water depth at the shore face location where waves start breaking.
Details: Accurate calculation of deep-water wavelength is crucial for coastal engineering, wave energy conversion, navigation safety, and understanding wave transformation processes as waves approach the shore.
Tips: Enter the equivalent unrefracted deepwater wave height in meters and the breaker height index. Both values must be positive numbers greater than zero.
Q1: What is the Breaker Height Index?
A: Breaker Height Index is the ratio of wave height and still water depth at the shore face location where waves start breaking.
Q2: What is Equivalent Unrefracted Deepwater Wave Height?
A: Equivalent Unrefracted Deepwater Wave Height (EDWH) is a parameter used particularly in wave behaviour and breakwater design, defined in relation to the Breaker Height Index from Linear Wave Theory.
Q3: When is this calculation most applicable?
A: This calculation is most applicable in deep water conditions where water depth is greater than half the wavelength, and wave behavior follows linear wave theory assumptions.
Q4: Are there limitations to this formula?
A: This formula assumes ideal conditions and may have limitations in shallow water, complex bathymetry, or with nonlinear wave interactions.
Q5: How accurate is this calculation for real-world applications?
A: While providing good estimates for many engineering applications, field measurements and site-specific factors should be considered for critical projects.
