Surf Similarity Number or Iribarren Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Surf Similarity Number or Iribarren Number = tan(Angle Sloped Plane forms with the Horizontal)/sqrt(Incident Wave Height/Incident Wave Length in Deepwater)
I_r = tan(α)/sqrt(H_i/L_o)
This formula uses 2 Functions, 4 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Surf Similarity Number or Iribarren Number - Surf Similarity Number or Iribarren Number is a dimensionless parameter used to model several effects of (breaking) surface gravity waves on beaches and coastal structures.
Angle Sloped Plane forms with the Horizontal - (Measured in Radian) - Angle Sloped Plane forms with the Horizontal is the inclination or tilt of the plane relative to the level ground.
Incident Wave Height - (Measured in Meter) - Incident Wave Height is obtained as the arithmetic mean of the wave heights measured by two gauges separated by a quarter of a wavelength [length].
Incident Wave Length in Deepwater - (Measured in Meter) - Incident Wave Length in Deepwater is the wave length of the wave that travels from the generating source towards the load.

STEP 1: Convert Input(s) to Base Unit

Angle Sloped Plane forms with the Horizontal: 16.725 Degree --> 0.291906317395997 Radian (Check conversion here)
Incident Wave Height: 160 Meter --> 160 Meter No Conversion Required
Incident Wave Length in Deepwater: 16 Meter --> 16 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_r = tan(α)/sqrt(H_i/L_o) --> tan(0.291906317395997)/sqrt(160/16)

Evaluating ... ...
