As stated on the Governing Equations page, the

The governing equation of GenCade is

δy/δt + (1/(DB+DC)) * (δQ/δx - q) = 0

This equation is solved with the inputs of boundary conditions and values for Q, q, DB and DC given.

The sand transport rates, Q, is taken from the 'CERC' equation for calculating longshore sediment transport. As formulated in Komar (1969):

Q = (H2Cg)ba1sin(2ɑb)

where H is the wave height (meters), Cg is the group wave celerity (meters/second), ɑb is the angle of the breaking waves to the shoreline, with the subscript b indicating the wave breaker position. Lastly, a1 is a non-dimensional parameter:
