Undular bores generated by fracture.
Hooper CG, Ruiz PD, Huntley JM, Khusnutdinova KR. Hooper CG, et al. Phys Rev E. 2021 Oct;104(4-1):044207. doi: 10.1103/PhysRevE.104.044207. Phys Rev E. 2021. PMID: 34781568
Undular bores, or dispersive shock waves, are nonstationary waves propagating as oscillatory transitions between two basic states, in which the oscillatory structure gradually expands and grows in amplitude with distance traveled. ...We demonstrate, using high-speed pointw …

Optical undular bores in Riemann problem of photon fluid with quintic nonlinearity.
Gao H, Wang DS. Gao H, et al. Phys Rev E. 2023 Aug;108(2-1):024222. doi: 10.1103/PhysRevE.108.024222. Phys Rev E. 2023. PMID: 37723744
Subsequently, the main basic wave structures arising from the discontinuous initial-value conditions are found by distinguishing the distributions of the Riemann invariants. Some exotic optical undular bores are observed by classifying the solutions of the Riemann problem …

Atmospheric undular bores.
Constantin A, Johnson RS. Constantin A, et al. Math Ann. 2024;388(4):4011-4036. doi: 10.1007/s00208-023-02624-8. Epub 2023 Apr 29. Math Ann. 2024. PMID: 38529401 Free PMC article.
We show that a recently-derived model for the propagation of nonlinear waves in the atmosphere admits undular bores as travelling-wave solutions. These solutions represent waves consisting of a damped oscillation behind a front that is preceded by a uniform breeze-type flo …

Undular Diffusion in Nonlinear Sigma Models.
Krajnik Ž, Ilievski E, Prosen T. Krajnik Ž, et al. Phys Rev Lett. 2020 Dec 11;125(24):240607. doi: 10.1103/PhysRevLett.125.240607. Phys Rev Lett. 2020. PMID: 33412011
Abyssal undular vortices in the Eastern Mediterranean basin.
Rubino A, Falcini F, Zanchettin D, Bouche V, Salusti E, Bensi M, Riccobene G, De Bonis G, Masullo R, Simeone F, Piattelli P, Sapienza P, Russo S, Platania G, Sedita M, Reina P, Avolio R, Randazzo N, Hainbucher D, Capone A. Rubino A, et al. Nat Commun. 2012 May 15;3:834. doi: 10.1038/ncomms1836. Nat Commun. 2012. PMID: 22588296 Free article.
Undular bore theory for the Gardner equation.
Kamchatnov AM, Kuo YH, Lin TC, Horng TL, Gou SC, Clift R, El GA, Grimshaw RH. Kamchatnov AM, et al. Phys Rev E Stat Nonlin Soft Matter Phys. 2012 Sep;86(3 Pt 2):036605. doi: 10.1103/PhysRevE.86.036605. Epub 2012 Sep 18. Phys Rev E Stat Nonlin Soft Matter Phys. 2012. PMID: 23031043
We develop modulation theory for undular bores (dispersive shock waves) in the framework of the Gardner, or extended Korteweg-de Vries (KdV), equation, which is a generic mathematical model for weakly nonlinear and weakly dispersive wave propagation, when effects of higher …

Generation of undular bores in the shelves of slowly-varying solitary waves.
El GA, Grimshaw RH. El GA, et al. Chaos. 2002 Dec;12(4):1015-1026. doi: 10.1063/1.1507381. Chaos. 2002. PMID: 12779625
We show that the nonlinear evolution of the shelf leads typically to the generation of an undular bore and an expansion fan, which form apart but start to overlap and nonlinearly interact after a certain time interval. ...

Undular bore solution of the Camassa-Holm equation.
Marchant TR, Smyth NF. Marchant TR, et al. Phys Rev E Stat Nonlin Soft Matter Phys. 2006 May;73(5 Pt 2):057602. doi: 10.1103/PhysRevE.73.057602. Epub 2006 May 4. Phys Rev E Stat Nonlin Soft Matter Phys. 2006. PMID: 16803084
An explicit simple wave solution of these modulation equations is then derived; this simple wave describing the evolution into an undular bore of an initial step. The characteristic on which the expansion fan occurs (propagating at a nonlinear group velocity) has a turning …

Numerical simulation of undular jumps on graveled bed using volume of fluid method.
Rostami F, Yazdi SR, Said MA, Shahrokhi M. Rostami F, et al. Water Sci Technol. 2012;66(5):909-17. doi: 10.2166/wst.2012.213. Water Sci Technol. 2012. PMID: 22797216
Undular hydraulic jumps are characterized by a smooth rise of the free surface, followed by a train of stationary waves. ...Furthermore, the free surface has a wavy shape, which may indicate the occurrence of several transitions from supercritical to subcritical states and …
