 rectional soliton gas</a>\nby Thibault Congy as part of Waves in One World
  (WOW) series\n\n\nAbstract\nThe soliton structure plays a fundamental rol
 e in many physical systems due to its fundamental feature: its shape remai
 ns unchanged after the collision with another soliton in the case of integ
 rable dynamics. Such particle-like behaviour has been at the origin of a n
 ew mathematical object: the soliton gas\, consisting of an incoherent coll
 ection of solitons for which phases (positions) and spectral parameters (e
 .g. amplitudes) are randomly distributed. The study of soliton gases invol
 ves the description of the gas dynamics as well as the corresponding modul
 ation of the nonlinear wave field statistics\, which makes the soliton gas
  a particularly interesting embodiment of the particle-wave duality of sol
 itons.\n\nMotivated by the recent realisation of bidirectional soliton gas
 es in a shallow water experiment\, we investigate two integrable models of
  bidirectional wave: the nonlinear Schrödinger equation and the Kaup-Bous
 sinesq equation. Using a physical approach\, we derive the so-called kinet
 ic equation that governs the gas dynamics for the two integrable systems. 
 We notably show that the structure of the kinetic equation depends on the 
 "isotropic" or the "anisotropic" nature of the solitons interaction.  Addi
 tionally we derive expressions for statistical moments of the physical fie
 lds (e.g. mean water level). As an illustration of the theory\, we solve n
 umerically the gas shock tube problem describing the collision of two "col
 d" soliton gases.  An excellent agreement with exact solutions of the kine
 tic equations is observed.\n

 ling dispersive water waves to shallow-water bores on a beach</a>\nby Onno
  Bokhove (University of Leeds) as part of Waves in One World (WOW) series\
 n\n\nAbstract\nPotential-flow water waves are coupled to a shallow-water m
 odel\, including hydraulic bores\, at a beach to deal with unidirectional 
 wave propagation in a finite domain. Such a set-up also matches wavetank c
 onditions used for testing and validation of model structures such as ship
 s in maritime engineering. Note that shorter\, non-breaking and dispersive
  waves in deeper water are thus damped by wave breaking at the beach. A su
 itable coupling point is chosen in sufficiently shallow water\, where the 
 two models are coupled by using variational techniques. Numerically\, a sp
 ace-time variational approach is followed for the potential-flow water wav
 es coupled to a classical finite-volume method for the shallow-water model
 . The entire approach has been validated numerically against bespoke wavet
 ank experiments undertaken at the TU Delft. The main work was performed by
  Floriane Gidel [1]\, in collaboration with Tim Bunnik and Geert Kapsenber

 d emission and irreversible dynamics during vortex reconnections in quantu
 m fluids</a>\nby Davide Proment (University of East Anglia) as part of Wav
 es in One World (WOW) series\n\n\nAbstract\nWe study the irreversible dyna
 mics of vortex reconnections in quantum fluids within the framework of the
  Gross–Pitaevskii model\, a nonlinear Schroedinger-type equation. We qua
 ntitatively explain the time-asymmetry characterising the reconnection pro
 cess by relating it to the emission of localised directional sound pulse. 
 Our theoretical results shed new light on energy transfer and turbulence i
 n fluid mechanics and have the prospect of being tested in quantum fluid e
 xperiments.\n

 ries\n\n\nAbstract\nIn this talk\, we will show how to reduce the problem 
 of analysing stability of solutions to nonlinear Hamiltonian PDEs\, to tha
 t of finding roots of polynomials. Using the Kawahara equation as an examp
 le\, it will be shown how to obtain explicit expressions for regions of st
 ability for different parameters in the equation. Finally\, we will illust
 rate how this can approach can easily be extended to more general PDEs.\n

 ge-amplitude solitary waves for the Whitham equation</a>\nby Erik Wahlen (
 Lund University) as part of Waves in One World (WOW) series\n\n\nAbstract\
 nIn the 1960’s G. B. Whitham suggested a non-local version of the KdV eq
 uation as a model for water waves. Unlike the KdV equation it is not integ
 rable\, but it has certain other advantages. In particular\, it has the sa
 me dispersion relation as the full water wave problem and it allows for wa
 ve breaking. The existence of a highest\, cusped periodic wave was recentl
 y proved using global bifurcation theory. I will discuss the same problem 
 for solitary waves. This presents several new challenges.\n\nJoint work wi
