Calculating Water Wavelength using Dispersion Relation and Approximation

by Chantelle Lee

Submitted : Fall 2018

The dispersion relation equation is used to directly compute wave number and wave length to compliment water wave pressure sensor readings. Waves are measured to help coastal engineering to better mitigate coastal infrastructures. Various given wave periods and water depths are used, within this paper, to show how the dispersion relation equation could compute wave length. Also, shallow and deep-water approximations were formulated from the dispersion relation equation and results were compared.
