Sobey RJ, 2014, Phase-resolving integral wave evolution in a coastal environment, Proceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics, Vol: 167, Pages: 167-194, ISSN: 1755-0777

<jats:p> The many and diverse approaches to phase-resolving integral wave evolution have no verification standard. A minimum candidate must be the propagation of steep progressive waves at uniform depth, a context that also provides exact estimates for the challenging advection and especially dispersion terms in the momentum equation. Heuristic scaling provides realistic and phase-resolving approximations to these advection and dispersion terms and a new set of phase-resolving integral wave evolution equations. Their predictive capability is explored for four problems with analytical association. </jats:p>

Sobey RJ, 2012, Steep progressive waves in deep and shallow water, Proceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics, Vol: 165, Pages: 181-200, ISSN: 1755-0777

<jats:p> Analytical solutions for steady progressive waves in deep and shallow water are developed and explored. The solution presentations emphasise the significant overlap in their formulations. Each theory is numerically confirmed as correct to fifth order and details of the solutions are archived in a manner that anticipates application code. Finally, the limits of validity, separate and overlapping, of the respective analytical solutions are extensively examined. It is suggested that ω<jats:sup>2</jats:sup>h/g ≈ 0·65 separates the region of applicability of the shallow and deep water theories. </jats:p>

Sobey RJ, 2012, A cnoidal approximation wave theory, Proceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics, Vol: 165, Pages: 201-216, ISSN: 1755-0777

<jats:p> Periodic progressive waves in shallow to transitional water are described by a cnoidal approximation wave theory. The formulation is analytical and largely classical. Periodic waves are assumed, so that the theory does not extend to solitary waves. The solution is completed numerically, as a problem in non-linear optimisation. The suitability of the theory in shallow to transitional water is demonstrated to 88% of the limit wave height. </jats:p>

<jats:p> A Stokes-style analytical theory for standing waves is developed and explored. The theory is numerically confirmed as correct to fifth order, and details of the solution are archived in a manner that anticipates the confirmation demands of application code. The uniquely non-linear aspects of the predicted kinematics are demonstrated in parallel with the equivalent linear theory prediction. Finally, the limits of validity of the analytical solution are examined, and lead to a preliminary but pragmatic estimate of limit standing waves. </jats:p>
