A 2d SWE - Linear Gravity Wave

  1. Aug 24, 2016 #1
    I have some questions about the 2D SWE (Shallow Water Equations).
    I would like to know if an exact (analytical) solution is available in the case of the (linear) surface "gravity" wave.
    Indeed, my example of interest is given by a square [0,L]2 with initial velocity field u = v = 0 and an initial Gaussian perturbation of the free surface elevation [math]h[/math] placed in the center of the domain:
    h(x,y,t=0) = H + η' exp [- (x - L/2)2 / (2 σx2 )] exp [- (y - L/2)^2 / (2 σy2) ]

    I know that, in 1D, a simple exact solution is available, which derives from a linearization of the Sain-Venant equations.

    Can you give me some references? (I am studying on Leveque, "Finite Volume methods for hyperbolic Problems" 2004)

    Thank you,
    Best regards,
