Our understanding and the fundamental questions about turbulence and mixing have kept developing since O. Reynolds and Boussinesq made turbulence a subject in 1880s. Pioneers such as Taylor, Prandtl, Richardson (of King's College), Kolmogorov (his paper was published 75 years ago!) and others developed the dynamical and statistical approaches. Conceptual developments and advances in practical modelling and prediction during the past 75 years, have benefitted from 3-dimensional measurement techniques and computer simulations at very high Reynolds number (>10 5), so that for example patterns, organised eddy structures, particle trajectories and conditional analysis can be better quantified and applied in practice. Papers at the conference cover a wide swath of topics from large scale instabilities that generate turbulence to small scale eddies that dissipates turbulence. Research into the interactions between turbulence and waves in engineering and geophysics, which are equally interesting and controversial, are also included in the conference, such as advances in water waves, KdV, solitons, Tsunami and Air-Sea interactions. Papers will be accepted for the conference based on a 500 word abstract for oral presentation. Abstracts should be submitted by Friday 13 November 2015 to Easychair via https://easychair.org/conferences/?conf=imatwm2016.
