“…The conservation properties of the MRLW equation related to mass, momentum and energy are determined by finding the following three invariants [16,22]: We take a = 1, c = 0.03, h = 0.2, Dt = 0.025, l = 1, x 0 = 0, À40 6 x 6 60 to compare our results with [17]. In order to find error norms and the invariants C 1 , C 2 , C 3 at different times, the computations are carried out for times up to t = 10.…”
