Lateral boundary conditions allow one to constrain the physics along boundaries in the model. They are similar to initial conditions, which specify the model state at start time. As an example, at the walls of a bathtub, the flow normal to the walls is zero since they are impermeable. For general information on the topic, see the Wikipedia article. Since ADCIRC solves for water elevations and velocities (fluxes), typically some aspect(s) of these two quantities is what is constrained at the lateral boundaries.
Flux Boundaries
By default ADCIRC weakly satisfies the no-flux boundary condition at mesh boundaries. See flux specified boundaries for details on fine-grained specification of the flux boundary conditions if required.
