Authors Zhiling Liao, Shaowu Li, Ye Liu, and Qingping Zou have noted a graphic error with Fig. 4 and a typographical error with Eq. (10) in their article “An analytical spectral model for infragravity waves over topography in intermediate and shallow water under nonbreaking conditions” that appeared in the September 2021 issue of the Journal of Physical Oceanography, Vol. 51, No. 9, pages 2749–2765, https://doi.org/10.1175/JPO-D-20-0164.1 (Liao et al. 2021). The corrected Fig. 4 appears here.

Fig. 4.
Fig. 4.

Theory–data comparisons of the spatial evolution of the amplitude and phase lag with respect to group forcing of group-forced infragravity waves for bichromatic wave groups with radian frequencies ω1 and ω2 on a sloping beach of hx = −1/35: the series A cases, Case A-1 to Case A-4, of Van Noorloos’s (2003) physical experiment (Exp.; circles), the exact solution (ES; solid lines), off-resonant linear solution [OLS; Eqs. (12) and (17) in the original article; dashed lines], and nearly resonant linear solution [NRS; Eqs. (19) and (21) in the original article; dotted lines] are presented. Wave parameters are h0 = 0.7 m and a1(x0) = 5a2(x0) = 0.06 m.

The corrected Fig. 4 shows that the exact solution and the near-resonant solution agree with the experimental results better as the difference frequency of incident bichromatic waves decreases. The errors are graphic and do not change the conclusions of the paper.

The corrected Eq. (10) reads
FXX+[(2Λ1+δ1)β1+2i]FX+[(Λ11)β2+(Λ2Λ1+1)β12+(2Λ1+δ1)β1iμ]F[Λ1β2+Λ2β12+(2Λ1+δ)β1i1]=0,
where the coefficient of β12F should be Λ2 − Λ1 + 1. The error is typographical and the correct equation was indeed solved in the original paper.
