| Abstract: | The nonlinear dispersion relations and Hedges have greater errors for small wave steep-nesses in shallow waters. To overcome this shortcoming, improved nonlinear dispersion relations are proposed by Li Ruijie. Based on summarization and comparison of the nonlinear dispersion relations given by Kirby, Hedges and Li, it can be found that the improved nonlinear dispersion relations given by Li not only retain the advantages of those by Hedges, Kirby and Dalrymple, but also significantly reduce relative errors in the range of relative water depth 1
