Wave Characteristics Calculator

This calculator allows setting the following values:

  • Input Wave Characteristics
  • Period, T
  • Depth, h
  • Average Wave Height, H
  • Calculated Wave Characteristics
  • Wavelength, L
  • Wave Number, k
  • Celerity, C
  • Group Velocity, Cg
  • Angular Velocity
  • Maximum Wave Height
  • Steepness

To assist in the design of coastal structures, the interface includes a one-dimensional wave run-up and overtopping calculator. This utility runs a 1D simulation with BOUSS-1D based on user specified parameters. To access the 1D Run-up and Overtopping calculator select the Calculators menu item in the BOUSS2D menu to bring up the BOUSS-2D Calculators dialog. The 1D Run-up and Overtopping calculator is a tab in the BOUSS-2D Calculators dialog. The BOUSS-2D Calculators dialog is always in the BOUSS-2D interface.

Input to the 1D Run-up and Overtopping calculator is organized into a spreadsheet. The first row of the input parameters spreadsheet is fixed and will contain the column titles given in the table below. The remaining rows contain the input parameters as shown in the dialog. The names and units columns are read-only. The value column is editable.


Parameter Value Units
Wave Type

Choose between “Regular” and “Irregular”. Titles of the wave height & period change depending on wave type. Default is “Regular”

-

Wave Height(H)(regular) or Significant Wave Height (Hs) (irregular)

Must specify

(m)

Wave Period(T) (regular) or Peak Period (Tp) (irregular

Must specify

(sec)

Depth at Toe of Breakwater (ds)

Must specify

(m)

Crest Elevation above Still Water (Zc)

Must specify

(m)

Side Slope (m)

Must specify

-

Offshore Slope (p)

Must specify

-

Chezy Roughness Coefficient

Must specify

m1/2/sec

Output of the calculator is displayed on the bottom portion of the dialog after the calculate button is clicked. The output is organized into a spreadsheet. When the dialog first comes up, the values in the output parameters spreadsheet are blank. The output parameters calculated are:

  1. Run-up, R. This value corresponds to Rmax for regular waves and R2% for irregular waves. The units of run-up are in meters
  2. Overtopping, Q. A single overtopping value will be computed. The units for overtopping are (m3/s)/m.
