Trapped wave phenomena are challenging to analyse and predict, as they usually require the study of partial differential equations (PDEs) with one or more complications from complex boundaries, variable co-efficients or non-linearity.  

The workshop will bring together researchers whose expertise spans geophysical flows (internal waves in the atmosphere and ocean, and topographic and planetary vorticity waves), surface water waves, complex dynamics and experiments, and the underpinning theory of waves in
fluids. These specialists come from different fields: pure and applied mathematics, atmospheric and ocean scientists, experimentalists and industry representatives with common interests in these problems. This workshop is a perfect environment for them to exchange ideas, borrow approaches from different fields, and start inter-disciplinary collaborations.

The scientific objectives of the proposed workshop are:

  • to create opportunities for researchers working in the area from a variety perspectives to interact and understand each others' results,

  • to identify and outline outstanding mathematical problems underpinning wave trapping and wave radiation

  • to encourage inter-disciplinary efforts and collaboration by establishing contacts between international leaders and early career researchers in the areas of mathematics, sciences and industry.


In particular, topics that the workshop will address include:

Trapping
- Self trapping arising from non-linear effects such as the generation of a mean field
- Topographic trapping arising from beaches, mountains, and variations of coastal topography slope
- Equatorial trapping arising from the variation in Coriolis effect in the equatorial region
- Stratification trapping from either refraction of high frequencies or trapped modal structures
- Trapping by currents and large scale flows
- Trapping associated with the critical latitude for near-inertial internal waves


Radiation
- Wave generation by flows over mountains or ocean topography
- Leaking of trapped modes by transmission through boundaries and high contrast regions
- Inelastic nonlinear wave interaction and dispersive radiation
- Localised forcing in a trapped wave context
- Resonant and critical flows
- Radiation from oceanic coastal-trapped waves propagating over planetary scales

Arrangements

The event will begin with registration around  08:30 on Monday 18 July and close around lunchtime on  Friday 22 July.

Participation

INVITED SPEAKERS

  • Invitees/Speakers should have already received and replied to their invitation online. Anyone who has not yet done so please can you do so as soon as possible. The invitation contains a link to your individual registration form.    

Registration Fee:
A 70.00 GBP registration fee is payable for this workshop.

  • Payment can be made on arrival at ICMS - at Registration we will accept cash, credit/debit card payments and sterling cheques (payable to “Heriot-Watt University”).  Unfortunately, we do not yet have an on-line payment system at ICMS.   If you wish to pay by credit/debit card, please complete the form (available in the link below) and bring the completed form to Registration.  

Venue and Talks
The workshop will be held at 15 South College Street, Edinburgh.  You may also find this map useful for the workshop.  All lectures will be held in the Newhaven Lecture Theatre.  The Lecture Theatre is equipped with a data projector, computer, visualiser (the new generation of overhead projectors) and two blackboards.  The projector and one board may be used simultaneously.  It is best to bring your presentation on a memory stick to use in our ICMS computer.  Alternatively, it is possible for you to use your own laptop with our dataprojector, but please be aware that you may have to alter your laptop resolutions/settings.   

Travel
Information about travel to the UK and Edinburgh is available here.

Please note that it is your responsibility to have adequate travel insurance to cover medical and other emergencies (volcanic ash disruptions) that may occur on your trip.

A taxi directly from the airport will cost approximately 16.00 to 20.00 GBP to the city centre for a one-way journey.  There is also a bus service direct from the airport to the city centre which will cost 4.00 single or 7.00 GBP return - the Airlink 100.  This is a frequent service (every 10 minutes during peak times) and will bring you close to Waverley Railway Station, only a short walk to the accommodation and the workshop venue (see map in 'Venue' section above). 

Lothian buses charge £1.60 for a single, £4.00 for a day ticket.  Please note that the exact fare is required and no change is given.

If travelling by train, please note that Edinburgh has several railway stations - Waverley Railway Station being the main station and closest to the workshop venue at 15 South College Street. If you alight at Edinburgh Waverley, the workshop venue is an easy 10 minute walk over North and South Bridge.  The other railway stations are Haymarket and Edinburgh Park at the West End of the city centre.

UK Visas
If you are travelling from overseas you may require an entry visa.  A European visa does not guarantee entry to the UK. Please use this link to the UK Visas site to find out if you need a visa and if so how to apply for one.

Accommodation
You will receive details of your accommodation in due course.

Catering
The workshop grant will cover refreshments throughout the event, lunch on three days, an informal wine reception and a workshop dinner.

Dinner
There will be a workshop dinner on Thursday 21 July at Blonde Restaurant, 75  St. Leonard's Street, Edinburgh.

Public lecture

On Tuesday 19 July, Paul Milewski (University of Bath), will give a Public Lecture  (title and abstract below).  Doors will open to the Public at 17.30, with the Lecture beginning at 18.00.  The Public Lecture will be followed by an informal wine reception in the Chapterhouse, Level 1, at ICMS from 19.00-20.00.  Seats have been reserved in the Lecture Theatre for all the workshop participants so there is no need for you to book a seat. 

When water waves act up: hydrodynamic laser and quantum analogues

"Water waves have been studied for centuries and are an endless source of fascination and difficult mathematical problems. In this talk we discuss how some recent work has shown that water waves can mimic behaviour of wave phenomena at two ends of the physics spectrum: extremely high energy lasers and quantum phenomena. We expect this second analogue  to help discern what behaviours in quantum mechanics are truly unique to the quantum world".
