Hey everyone,

I'm writing a FORTRAN Code for simulating the propagation of shallow water waves (1D). The case is pretty simple: I have a wave generator on one end of the pool and a Wall boundary condition on another. I'm using the Lax Wendroff Method. The equations have the form:
!
! dh/dt + dA/dx = 0
!
! dA/dt + dB/dx = C

The difficulty which I am facing is the implementation of the Boundary Conditions for the half time steps. For this reason, I haven't been able to initiate wave propagation over the surface. Anybody with experience is welcome to comment so that I may share more detail and/or code.
