Analytical Solution

The analytical solution for wind setup over a constant depth is given by \begin{equation} \tag{1}

 \eta = \sqrt{2  \frac{\rho_a C_d  W^2}{\rho g} (x + C ) + h^2} - h

\end{equation}

where is the water surface elevation, is the water density, is the air density, is the gravitational acceleration, is the wind speed, is the water depth, and is a constant of integration.

Model Setup

A computational grid with constant water depth of 5 m and irregular boundaries is used in order to test the model performance. The computational grid has 60 columns and 70 rows and a constant resolution of 500 m.
