sshi02 / wavenumber

wavenumber.py

CLI tool for quick evaluation of wavenumber, wavelength, and depth to wavelength ratio.
A recursive Newton-Raphson function and shallow-water approximation are used to calculate and output the above.

arguments

• -h water depth
• -T period
• -w angular frequency
• -e error

usage

At minimum, the tool needs depth (-h) and either period (-T) or angular frequency (-w) to run.

• The tool will not accept both a period and an angular frequency for clarity reasons.

The error (-e) is an optional argument, used for establishing the desired margin between guesses from the Newton-Raphson method.

• By default the error is e-5.

example 1

python3 wavenumber.py -h 5 -T 10

example 2

python3 wavenumber.py -w 0.63 -e 0.01 -h 8
