What is Return Period?
Extreme conditions in coastal engineering are often described in terms of return values and return periods. A Return Period, also known as a recurrence interval or repeat interval, is an average time or an estimated average time between events such as earthquakes, floods, landslides, or river discharge flows to occur.
How to Calculate Significant Wave Height for Free Long Waves?
Significant Wave Height for Free Long Waves calculator uses Significant Wave Height for Free Waves = (Constant for Free Long Waves*Significant Wave Height^1.11*Design Wave Period^1.25)/Water Depth^0.25 to calculate the Significant Wave Height for Free Waves, The Significant Wave Height for Free Long Waves formula is defined as to estimate a bound long wave Hs and empiricism to estimate a free long wave Hs including both edge waves and leaky waves. Bowers observed that bound long waves increasingly dominate free long waves as wind wave/swell Hs increases. Significant Wave Height for Free Waves is denoted by Hsf symbol.
How to calculate Significant Wave Height for Free Long Waves using this online calculator? To use this online calculator for Significant Wave Height for Free Long Waves, enter Constant for Free Long Waves (K), Significant Wave Height (Hs), Design Wave Period (Tp) & Water Depth (D) and hit the calculate button. Here is how the Significant Wave Height for Free Long Waves calculation can be explained with given input values -> 16.57771 = (0.0041*65^1.11*31^1.25)/12^0.25.
